Abstract

:
This paper aims to understand better how attitudes towards the environment could influence preferences and willingness to pay for the development of sustainable tourism products on the Spanish island of Gran Canaria. A hybrid choice model is estimated to analyse how different latent constructs related to environmental concerns affect individuals’ preferences for a set of sustainable tourism activities. The data used in the analysis are obtained from a discrete choice experiment where different scenarios with nature-based tourism packages are created. A set of measurement indicators allowed us to gain insight into the underlying latent structure regarding the individuals’ attitudes towards the environment. The analysis consists of integrating these attitudes into a choice model, focusing on a market segment primarily composed of potential customers who are young residents and non-residents. The results reveal significant heterogeneity in preferences and willingness to pay for the various activities under study when attitudinal latent factors are incorporated into the model. Our findings provide valuable insights for researchers, policymakers, and practitioners promoting sustainable tourism products.

1. Introduction

According to the United Nations World Tourism Organization (UNWTO), around 1.45 billion people visited foreign countries in 2019. Global tourism spending was estimated at EUR 1468 billion, generating 334 million jobs, making it one of the world’s largest economic sectors [1]. As a consequence of the global COVID-19 pandemic, these figures plummeted over the next two years, and countries heavily reliant on tourism suffered a significant decline in economic activity, which also led to a reduction in the externalities generated by the overexploitation of tourism resources. In this sense, the post-pandemic scenario represents an opportunity for countries to undertake the required reforms to achieve more sustainable tourism development.
Global concern about the state of the environment and the need for sustainable practices in all aspects of life has grown in recent years. The tourism industry has witnessed an important transition towards sustainable tourism as visitors become more aware of their impact on the places they visit. In this regard, attitudes towards the environment are crucial in shaping preferences for sustainable tourism, influencing travellers’ behaviour and processes [2,3,4].
In particular, one of the most interesting trends observed in recent decades has been the shift from vacationing for relaxation and recreation to more health and quality-of-life-related vacation experiences, which include more sports and adventure activities. The UNWTO predicted that active and adventure travel related to nature and culture would be one of the primary sources of tourism revenue growth [5]. According to De Knop [6], “sports and active recreation during the holiday has become very successful, probably due to increased urbanization and of changing leisure time pursuit”. Sport’s significance in tourism can also be seen in the scientific context, where academics have increasingly integrated the two disciplines into a scientific theme. Sport & Tourism, a scientific journal founded in 1993, exemplifies this trend.
This article aims to contribute to the academic understanding of consumer behaviour and the environmental attitudes that underpin sustainable tourism choices. In particular, this study considers a hybrid choice model to analyse how attitudes towards the environment influence preferences and willingness to pay for sustainable tourism products on the Spanish island of Gran Canaria. The analysis consists of integrating these attitudes, represented by a set of latent variables, into a choice model and focuses on a market segment comprised primarily of potential customers who are young residents and non-residents with a strong interest in nature tourism. The sample ensures a certain homogeneity in the researched group in terms of common interests as well as similar budgetary constraints.
Although the island is best known for being a popular year-round mass tourism destination, it also offers many landscapes and microclimates. It is often referred to as a miniature continent. These features enable visitors to participate in a variety of tourism and sports activities that are more environmentally friendly. Beach activities, mountain and water sports, and cultural activities are among them. A year-round warm climate, with an average monthly temperature of 20 degrees Celsius, contributes to this [7].
Gran Canaria is dominated by hotel and mass tourism, which often has adverse effects on environmental and social issues, such as pollution and a decrease in the quality of life of the local residents. Therefore, a thorough understanding of consumer preferences in this context would be highly beneficial to promote active, more nature-based, eco-friendly and environmentally sustainable tourism activities. Thus, the main motivation of this study is to analyse whether Gran Canaria and other similar tourist destinations could promote alternative forms of tourism that benefit nature, culture, and the local population.
Nature-based tourism has the potential to offer sustainable tourism products that are different from the traditional mass tourism products based on sun, sea, and sand (3S). Gran Canaria is a famous destination in the EU for such mass tourism products, but it is essential to develop alternative sustainable tourism products. Nature-based tourism developments require specific environments where certain activities and attractions can be marketed to particular segments [8].
Tourists’ environmental attitudes significantly influence their preferences, but how these could impact nature-based tourist product development is under-researched, either by the use of proper scales measuring the environmental attitudes or by the characteristics of the tourist products developed. Therefore, this study aims to fill this gap by analysing how environmental attitudes, categorised into three latent variables—community support, nature interaction, and nature connection—shape nature-based tourists’ preferences. In addition, the WTP figures are indirectly obtained from model parameters for a group of activities, including diving/snorkelling, active hiking, cultural trails, and star gazing for tourists who could be accommodated in a tent or rural house.
Thus, our study contributes to the scarce research on understanding pro-sustainable behaviour and its influence on the economic implications [9]. To our knowledge, this is the first time the hybrid choice model has been applied using the environmental concern scale and the type of activities included in the analysis. This study also investigates the development of a potential commercial tourist area in Veneguera, a protected natural space located in the south of Gran Canaria that is rich in natural resources running along a beautiful ravine and pristine coastline.

2. Literature Review

Growing environmental concerns and increased ecological awareness have impacted consumer habits worldwide. Budeanu [10] contended that a limited understanding of the dynamics between different determinants of tourists’ sustainable behaviour could hinder the tourists’ choices of more sustainable alternatives. In addition, assessing tourist demand, motivations, preferences, and willingness to pay (WTP) an extra premium for more sustainable tourist alternatives is crucial for investors and operators interested in developing environmentally friendly tourist products that promote nature conservation and more sustainable tourist consumption [11,12].
Tourists’ choices are influenced by promoting their behaviour towards more sustainable options in the whole chain of the tourism industry [13]. Some previous studies found that biospheric values, positive attitudes towards sustainable tourism, and higher levels of affinity towards diversity can predict more sustainable tourism choices, while personality traits play a more indirect role [14]. Other studies also found connections between environmental attitudes and sustainable tourism choices. For example, Santos et al. [15] analysed attitudes towards more sustainable academic conferences depending on some sociodemographic variables. An extensive review of studies can be consulted in [16].
Different modelling approaches are used in the literature to analyse this connection from qualitative, quantitative, and triangulation methods; smart partial least squares; exploratory factor analysis; structural equation models; latent variable methods; and discrete choice methods. After reviewing fifty-nine papers that analyse this connection, we deduced that one of the methods that has been more used in the last decade is the smart partial least squares method. Nevertheless, hybrid choice models like the one used in this study have not been so commonly used.
For example, Sultana et al. [17] found, using a partial least square method (PLS), a significant positive influence of perceived green knowledge and green trust on customers’ intention to visit green hotels in Dhaka, Bangladesh. Nowacki et al. [18] used a similar PLS approach to find significant relationships between attitudes towards the environment, an eco-friendly destination, social and personal norms and behavioural control, with intentions to travel to eco-destinations. However, the same study also found a very weak relationship between positive attitudes towards environmentally friendly destinations and the willingness to pay a premium for a more environmentally conscious trip. Thus, the authors found that even though tourists have a positive attitude towards sustainable tourism, only some of them are willing to pay higher prices for sustainable tourism purchases, green transport choices, and responsible behaviour in the destinations.
Pinho and Gomes [19] also used a PLS model to demonstrate the existence of a dissonance between the tourists’ interest in the Sustainable Development Goals (SDGs) and their behaviour when they are travelling. Thus, the authors showed that most of the Portuguese participants were interested in choosing a sustainable destination, but on the other hand, they did not show the same interest in preserving the sustainability of the destinations or in demonstrating pro-environmental habits. Wahnschafft and Wolter [12] used a triangulation approach to find that a small extra willingness to pay existed for more sustainable excursions on environmentally friendly tourist boats in the context of solar-battery-electric boats cruising the Spree River in downtown Berlin. During interviews, several passengers expressed their desire for a more sustainable form of boat excursion, even if it meant paying a higher price. All customer groups were willing to pay the extra premium regardless of their preferences, motivations, consumption patterns, and interests.
Moreover, other studies are inconclusive and find different tourist segments that support sustainable tourism development. Puciato et al. [20] used a systematic literature review and found that tourists with higher levels of education and financial status, as well as younger travellers, are more likely to accept higher prices for sustainable services. Pulido-Fernández and López-Sánchez [9] also found different segments investigating if tourists are willing to pay extra premiums for sustainable destinations. To that aim, the authors used a logistic regression model to show that tourists with a greater level of commitment, attitude, knowledge, and behaviour regarding sustainability, named pro-sustainable tourists, are willing to pay more to visit sustainable destinations in the Costa del Sol, Spain. However, at the same time, there is also an important segment which is reluctant to pay the extra premium.
Sultana et al. [17] highlighted the need to study the young generation, because this segment will be the largest group of travellers in the future. The authors used a PLS model to find a significant positive influence of perceived green knowledge and trust on customers’ green hotel visit intention. Gan and Nuli [21] also studied young tourists’ sustainable choices, finding that environmental awareness was an important driver of millennials’ willingness to pay for green hotels. However, the Malaysian millennials’ green hotel demand must be viewed in the context of a relatively low environmental awareness compared to the current study.
Nowacki et al. [22] found that the perceived green image of a destination has the strongest impact on Gen Z’s intention to travel to a destination and that this perception has more impact than the pro-environmental attitudes towards green tourism and personal norms. They concluded that the WTP and extra premium are more significant for Gen Z than for other generations. The authors also showed the existence of intercultural differences among Indians and Poles and challenged other researchers to contribute to shedding more light on this topic using other destinations and cultural groups. Moreover, Gen Z is becoming a popular trait studied in tourism [23,24].
Campos-Soria et al. [25] used a hierarchical linear model to show that tourists’ environmental concerns are influenced by individual- and travel-related factors and their place of residence. The authors found that the different trends observed in European countries are mainly due to differences in economic, cultural, and environmental factors and that such between-country differences mainly explain the heterogeneous pattern. Frank et al. [26] also found some country differences in analysing the nature-based (surf) products in the Algarve, Portugal. Their study found that the WTP is related to nationality, with respondents from Germany, Austria, and Switzerland showing higher WTP figures. Nevertheless, contrary to the current study, WTP figures were directly obtained by the questionnaire, which usually offered biased and less-accurate results [27].
The section ends with studies that used latent variables and hybrid choice models that have been recently applied in tourism. As previously said, the literature is still scant. For example, Albadalejo and Díaz-Delfa [28] analysed the rural accommodation choice process using a hybrid discrete choice (HDC) that takes into account latent motivation variables through a multiple indicator multiple cause (MIMIC) model. The results showed that motivations affected the rural accommodation choice and interacted with other attributes that depend on the accommodation characteristics. In a similar fashion, Masiero and Hrankai [29] analysed the transport modal choice of some urban destinations, studying the less-visited, peripheral, uncongested areas. The authors provided a methodological framework based on tourist accessibility for peripheral urban attractions. A discrete choice experiment was designed to investigate latent variables according to different types and ratings of tourist attractions and the main characteristics of mass public and private transport alternatives. The authors estimated a hybrid choice model, finding that repeat visitation, length of stay, and public transport system perceptions were determinants of the tourists’ modal choice. Song et al. [30] also used a hybrid choice model to investigate low-carbon footprint travel choices, considering as latent variables both destinations and climate change perceptions. The authors also examined the impacts of nudging, altering tourists’ behaviour that mitigated the carbon footprint in destinations. Their study found that the destination type, carbon emissions, and travel cost had significant effects on tourists’ choices of destinations, and nudging was a great tool to reduce the tourists’ carbon footprint. Tourists who were more aware of climate change were more likely than others to select low-carbon destinations.

3. Methodology

3.1. Data and Choice Experiment

The dataset used in the analysis is obtained from a discrete choice experiment (DCE), which allowed us to determine individuals’ preferences and willingness to pay for various active tourism activities. The DCE was integrated into a questionnaire with attitudinal questions and a section for gathering socio-demographic data. Other sections of the questionnaire were not used in the present research.
DCEs represent an adequate data-collection tool that is very helpful in understanding how individuals make decisions. Since the method generates hypothetical choice scenarios, they are handy for analysing the demand for alternatives that have not yet been marketed [31]. Moreover, DCEs have a solid theoretical foundation anchored in the discrete choice theory [32] and have emerged as a vital instrument in various areas such as transportation, health, and environmental research.
Some popular outdoor activities are investigated in our experiment, where tourists can explore rural lifestyles and interact with rural communities. These activities will take place in Veneguera, Gran Canaria, declared a protected natural space in 2003, rich in natural resources, that runs along a stunning ravine and a pristine coastline. A map of the study area is included in the Annex (Figure A1).
When choosing activities, those that could be addressed to a large audience were considered, as well as those that could be implemented in the natural space under investigation. As a result, the tested attributes include active hiking trails that include visits to some natural spots, such as the “Blue Pools of Veneguera”, a more culturally oriented version of hiking, and guided group activities such as snorkelling/scuba diving and star gazing. The lodging type and the vacation package cost were also considered. The context of the experiment is designed to create a simulated tourist experience for a group of four individuals over a weekend, spanning two nights. The participants are provided with opportunities to engage in various activities that enable them to appreciate and enjoy the natural environment in a sustainable manner. The activities studied followed Pesonen’s categorisation of rural tourism clusters, which include active, passive, nature, and aquatic activities [33]. According to this author, activity segmentation is a more useful segmentation approach than using travel motivations to reach different market segments.
In the choice experiment, respondents answered twelve choice scenarios defined by two hypothetical active tourism packages and a non-choice alternative. The choice scenarios were obtained by combining the different levels of the attributes considered in the analysis through an efficient design built using the software Ngene 1.0 [34]. The definition of the attributes’ levels is shown in Table 1. Thus, the alternative chosen by the individual would be regarded during the modelling process as the one that maximises his utility based on the behavioural rule of utility maximisation.
The experiment consisted of 12 choice scenarios, so each participant provided 12 statistical observations. A total sample of 476 individuals was collected, generating 5712 valid observations for model estimation. The sample was evenly distributed by gender and between Gran Canaria residents and non-residents, with a slightly greater proportion of active workers (53.3%). Sampled individuals had an average age of 23.6 years and a monthly income of EUR 481. The non-resident sample was drawn from participants in a summer sports camp in a small village in the southwest of France and was primarily made up of Germans. The sample of residents was mainly obtained from university students randomly recruited in different campus locations. Trained interviewers completed all the questionnaires through face-to-face interviews to ensure the quality of the information obtained.
The attitudinal questionnaire included nine items or indicators related to the individuals’ environmental concerns in the context of an ecotourism trip. Answers were collected using a 5-point anchored semantic scale, where 1 means low importance, and 5 means high importance. Table 2 shows the description of the items included in the analysis as well as their justification after a literature review about nature-based ecotourism products.
There is no agreement in the literature regarding the sustainability of ecotourism activities. While Ruhanen et al. [35] argue that ecotourism and sustainable tourism are equivalent concepts, some authors contend that ecotourism is not always sustainable [36]. Weaver and Lawton [37] suggest that ecotourism attractions should be nature-based and focused on learning and education, with product management pursuing ecological, socio-cultural, and economic sustainability.
In order to gain insight into the underlying latent structure regarding the individuals’ concern for the environment, an exploratory factor analysis (EFA) was performed to determine the existence of latent factors that explain the variability of the scores obtained in the indicators used as a measurement instrument. These latent factors will be integrated a posteriori into the structure of the hybrid choice model.
The results of the EFA are presented in Table A1 in the Annex. Three latent factors are identified, namely, community support (CS), nature interaction (NI), and nature connection (NC) using the Varimax rotation method. The results obtained for Barlett’s sphericity test [38] suggest the existence of correlations between the indicators that allow the dimension to be reduced. In addition, the Kaiser–Olkin–Meyer test [39] was 0.828, confirming the adequacy of the sample to perform an EFA.
Community support tourism is also known as community-based tourism (CBT) [40], which is mainly defined as the ability to improve the quality of life of the local residents [41]. Developing such products improves the number of facilities, roads, parks, and other types of infrastructure, benefitting the residents’ quality of life without disrupting the local culture [42].
Environmental attitudes also interact with nature-based tourist products, and the activities developed in natural settings have also been influenced by tourists’ preferences. Nevertheless, the challenges imposed by nature-based tourist developments regarding environmental preservation have been controversial in the tourist literature [43]. Lee and Jan [44] contended that nature-based tourism is mainly based on the recreational feelings tourists experience from their contact with natural settings. For example, when tourists observe wildlife, they establish a close connection with them and consider protecting their environment and habitat important.
Nature connection is related to what other authors have denominated as a biospheric value representing personal moral norms about responsible behaviour towards the environment, nature, or non-human objects [45]. Thus, a biospheric attitude uniquely explains a more pro-environmental behaviour associated with green consumption in the whole value chain that agglutinates the tourist experience [46]. Van der Werff et al. [47] showed that tourists with a higher biospheric value are more personally connected to nature and the environment. For that reason, they are more naturally inclined towards protecting nature, ecosystems, and the environment.

3.2. The Hybrid Choice Model

Based on the assumptions of the Theory of Planned Behaviour [62], where attitudes and perceptions play an important role in determining individuals’ choice behaviour, this paper estimates an integrated choice and latent variable model (ICLVM) to analyse how different latent constructs related to environmental concern influence preferences for sustainable tourism activities. After the seminal work of McFadden [63] as well as posterior contributions of Ben-Akiva et al. [64,65], ICLVM, also referred to in the literature as hybrid choice models (HCM), are currently considered the appropriate tool to incorporate the effect of latent variables into discrete choice models [28,29].
Latent variables (LVs), such as attitudes and perceptions, represent intangible attributes not directly observed by the researcher but that may affect an individual’s decisions. These variables do not account for specific measurement scales, so they must be indirectly measured through indicators that manifest the underlying latent structure.
LVs are typically derived from a multiple indicator multiple causes (MIMIC) model, in which individuals’ socioeconomic characteristics explain these variables through structural equations. LVs, in turn, explain a collection of indicators through a set of measurement equations. LVs are then incorporated into the choice model as explanatory variables. In our case, LVs are specified by interacting with some of the attributes of the experiment. The parameters of the structural equation and the choice model are estimated simultaneously using the full information likelihood function.
The structure of the hybrid choice model is depicted in Figure 1, and the specification of the equations of the different model components are as follows:
(1)
The MIMIC model
(a) Structural equations
In the structural equations, the LVs are treated as random variables explained by a set of observed factors, such as socioeconomic data and a random term. In our model, the following structural equations for community support, nature interaction, and nature connection are considered:
C S = β 0 C S s + β G E N D E R C S s G E N D E R + β A G E C S s A G E + β W O R K C S s W O R K + β R E S I C S s R E S I + β I N C O M E C S s I N C O M E + σ S ε S N I = β 0 N I s + β G E N D E R N I s G E N D E R + β A G E N I s A G E + β W O R K N I s W O R K + β R E S I N I s R E S I + β I N C O M E N I s I N C O M E + σ S ε S N C = β 0 N C s + β G E N D E R N C s G E N D E R + β A G E N C s A G E + β W O R K N C s W O R K + β R E S I N C s R E S I + β I N C O M E N C s I N C O M E + σ S ε S
where GENDER is 1 for males, AGE is 1 if the individual is older than 22 years, WORK is 1 for active workers, RESI is 1 for residents in Gran Canaria, and INCOME represents the monthly income in thousands; the set of coefficients β i s and σ S are unknown parameters to estimate; and ε S is a random variable following the Standard Normal distribution.
For the sake of simplicity, the structural equations can be rewritten as
C S = C S ¯ + σ S ε S N I = N I ¯ + σ S ε S N C = N C ¯ + σ S ε S
where C S ¯ , N I ¯ , and N C ¯ represent the mean of the latent random variables.
(b) Measurement equations
As stated above, LVs are indirectly measured by a set of indicators. Thus, measurement equations represent the relationship between the LV and the measurement instrument. Considering the latent structure obtained in the previous EFA, the measurement equations represent the indicators as random variables through the following expressions:
I 3 = β 0 3 m + β C S 3 m C S ¯ + σ 3 * ε 3 * I 4 = β 0 4 m + β C S 4 m C S ¯ + σ 4 * ε 4 * I 5 = β 0 5 m + β C S 5 m C S ¯ + σ 5 * ε 5 * I 9 = β 0 9 m + β C S 9 m C S ¯ + σ 9 * ε 9 * I 6 = β 0 6 m + β N I 6 m N I ¯ + σ 6 * ε 6 * I 7 = β 0 7 m + β N I 7 m N I ¯ + σ 7 * ε 7 * I 8 = β 0 8 m + β N I 8 m N I ¯ + σ 8 * ε 8 * I 1 = β 0 1 m + β N C 1 m N C ¯ + σ 1 * ε 1 * I 2 = β 0 2 m + β N C 2 m N C ¯ + σ 2 * ε 2 *
where ε j * are random variables following the Standard Normal distribution, and coefficients β i m and σ j * are parameters to estimate. As not all the parameters are identifiable, the intercept coefficients β 0 3 m , β 0 6 m , and β 0 1 m are normalised to 0; the slope parameters β C S 3 m , β N I 6 m , and β N C 1 m are normalised to 1; and the standard deviations σ 3 * , σ 6 * , and σ 1 * are normalised to 1.
Depending on the nature of the indicators, they can be treated as continuous or discrete variables. In our case, we use a semantically ordered scale of importance as a measurement instrument. Therefore, indicators are represented by discrete ordered variables. Thus, each measurement equation represents a latent regression that can be modelled using an ordered Probit model, where each score is identified as pertaining to a category delimited by specific threshold values of the dependent variable. Four threshold values could be estimated for 5-point scales. However, the assumption of symmetry in the indicators could reduce the number of parameters to just two by considering   δ 1 > 0 and δ 2 > 0 so that the thresholds are defined as τ 1 = δ 1 δ 2 , τ 2 = δ 1 , τ 3 =   δ 1 and τ 4 = δ 1 + δ 2 (see Greene and Hensher [66] for a comprehensive revision of ordered choice models).
(2)
The choice model
The utility of the alternatives in the choice model is defined in terms of the attributes considered in the experiment and the LVs obtained from the MIMIC model. Incorporating these LVs variables into the choice model was in the form of interactions with the attributes of the alternatives. Different specifications were tested during the modelling process, and the one producing more consistent results was that considering the interactions of community support and the accommodation type and cultural trail; nature interaction and active hiking, diving/snorkelling, and stargazing; and nature connection and the alternative specific constant of the non-choice option. Thus, the utility of the alternatives is specified as follows:
U A l t   1 = β P P 1 + β A C + β A C _ C S C S A C 1 + β C T + β C T _ C S C S C T 1 + β A H + β A H _ N I N I A H 1 + β D S + β D S _ N I N I D S 1 + β S G + β S G _ N I N I S G 1 + ε 1 U A l t   2 = β P P 2 + β A C + β A C _ C S C S A C 2 + β C T + β C T _ C S C S C T 2 + β A H + β A H _ N I N I A H 2 + β D S + β D S _ N I N I D S 2 + β S G + β S G _ N I N I S G 2 + ε 2 U N o n c h o i c e = β A S C 3 + β A S C 3 _ N C N C + ε 3
where β i are parameters to be estimated, and the explanatory attributes are named as in Table 1.
Assuming the error terms ε j are iid Extreme Value Type I distributed, the choice probabilities for the multinomial Logit model can be derived [67]. It is worth noting that attribute coefficients are interpreted as marginal utilities; thus, calculating the ratio of these marginal utilities and the negative of the price coefficient, the willingness to pay figures (WTP) are obtained [32].
There are different approaches to estimating the parameters of the hybrid choice model. Sequential estimation entails first estimating the MIMIC model and then including the latent variables in the specification of the choice model in a subsequent stage. Although this is a relatively straightforward strategy, it yields inefficient estimates. In this sense, Bierlaire [68] suggests simultaneously estimating the parameters of the structural and choice models by considering the full information likelihood function obtained from indicators and choice data.

4. Results

Estimation results are presented in Table 3. Unknown parameters were estimated using the simulated maximum likelihood method with the software Pandas Biogeme 3.2.8. [68]. All the measurement model parameters were significant and estimated with the appropriate sign. All the slope parameters were positive, consistent with the measurement instrument used for the latent factors. Thus, a higher value of the corresponding LV would be compatible with a higher score obtained for the indicator. In this sense, we highlight that all the items included in the measurement model were positive; that is, a higher value of the indicator means a stronger environmental concern.
In the structural model, all parameters were significant at the 95% confidence level, with the only exceptions of income in community support and nature interaction and work in nature connection. Regarding the impact of socioeconomic characteristics on the different LVs, females, local residents, those not currently working, and those younger than 22 have stronger community support attitudes. Females, non-local residents, those not currently working, and those younger than 22 have stronger nature interaction attitudes. Finally, females, non-local residents, those younger than 22, and those with lower income present stronger nature connection attitudes. In addition, the intercept parameters were all positive, indicating that other unknown factors positively impacted the three LVs’ attitudes towards the environment.
In the choice model, our results support the hypothesis that attitudes related to environmental concerns affect choice behaviour. In this case, most of the parameters were significant at the 95% confidence level, except the reference coefficients for active hiking ( β A H ), cultural trail ( β C T ) and stargazing ( β S G ). These results indicate that including these activities in the package is preferred by those with positive and non-negligible attitudes towards nature interaction and community support. In contrast, accommodation in a rural house and diving/snorkelling activity would be preferred, even for individuals for whom these attitudes were represented by figures close to zero.
It is important to stress that negative attitudes may lead to a negative preference—i.e., a negative marginal utility—for the attribute in question. In our model, the majority of individuals presented positive attitudes towards community support (84.87%), nature interaction (97.18%), and nature connection (94.45%). Our findings show that individuals with stronger community support attitudes exhibit stronger preferences for rural house accommodation and cultural trail activities. In addition, individuals with stronger nature interaction attitudes have a stronger preference for active hiking, diving/snorkelling, and stargazing activities. On the contrary, individuals with a stronger attitude related to nature connection show a lower preference for active tourism packages; in other words, they have a stronger preference for the no-choice option. Figure 2 depicts the preference for the no-choice option regarding nature connection. The graphic shows that, for most individuals, the constant term of the no-choice alternative is negative, suggesting the existence of unobservable factors that indicate a clear preference for alternatives offering sustainable tourism packages when the effect of the characteristics of the package itself is considered negligible.
In monetary terms, the willingness to pay for improving an attribute (Xi) of alternative i represents the increases in the utility of the alternative V i produced by this improvement. They can be obtained from the choice model parameters using the following expression [67]:
W T P X = V i X i V i P r i c e i
where the partial derivatives are replaced by increments for discrete attributes.
In our model, the numerator in the former expression varies across individuals, as the explanatory attributes representing the activities considered in the package and the type of accommodation interact with some of the LVs considered in the analysis.
Figure 3 shows the WTP for the accommodation in a rural house and cultural trail activity regarding the LV community support. It is important to note that the WTP for cultural trails yields a negative figure (15.8%) for some individuals, indicating that they perceive a negative utility when this activity is included in the package. The result will have important managerial implications suggesting incorporating compensation mechanisms when designing the tourism packages to meet this market segment’s needs.
The WTP figure in terms of the LV nature interaction is depicted in Figure 4. The graphic shows that for all the individuals in the sample, diving/snorkelling is the most valued activity, followed by active hiking and stargazing. In this case, the proportion of individuals with negative WTP is substantially lower: 1.9% for active hiking, 0.02% for diving/snorkelling, and 8.9% for stargazing.
Table 4 presents the average WTP figures for the whole sample and the socioeconomic groups studied. Thus, on average, diving/snorkelling activities have the highest WTP (EUR 35.40), followed by active hiking (EUR 23.53). On the other hand, cultural trails and stargazing are the least valued, with EUR 13.87 and EUR 11.43, respectively. It is also worth pointing out that individuals are willing to pay EUR 11.72 to stay in a rural house rather than a tent. In general, females and those under 22 exhibit higher WTP figures for all the attributes. Similar figures are obtained for active and non-active workers, except in the case of the cultural trail, where non-active workers are willing to pay EUR 2.7 more. Residents in Gran Canaria are willing to pay more for being accommodated in a rural house and for having cultural trails in the packages. In contrast, non-residents value active hiking trails, diving/snorkelling, and stargazing activities more. These results are consistent with the parameter estimates obtained in the structural model and highlight the importance of incorporating latent variables into the choice model.

5. Discussion

Our findings are not easily comparable to previous studies because, to our knowledge, this empirical analysis is applied for the first time considering the environmental concern scale and the type of ecotourism development in Gran Canaria. Another important difficulty in comparing the results has its origin in the young sample of respondents used in the study. Nevertheless, the results have important managerial implications, providing interesting information for those designing nature-based tourism products. In this regard, knowing the amount different market segments are willing to pay for a particular activity is paramount in creating successful product packages that consider the normally hidden tourists’ preferences. This is especially relevant in the context of a mass tourism destination where young consumers could help in moving towards more sustainable tourism activities.
The community support dimension includes the following indicators: knowing and sharing the customs and traditions of the peoples, carrying out agricultural and livestock activities in a traditional way and with low impact, promoting the economic development of communities where ecotourism activities are carried out, and recovering trails and routes for ecotourism purposes. The study found that females, local residents, those not currently working, and those younger than 22 had stronger community support attitudes, and that 84.87 per cent of the sample presented positive attitudes towards community support. The results are similar to those found by Buffa [69], where the author contended, analysing a sample of 1156 young Italians, that “most young tourists say they prefer local food, adapt as much as they can to the traditions and customs of the place in which they are holidaying, try to learn about their destination before travelling, would be willing to be involved in events organised by the local community and to interact with it, demonstrate interest in the protection of the authenticity of the destination, even if this means going without certain comforts, find out how to protect the local environment and reduce waste, and are concerned to ensure that their spending benefits the local population (p. 14051)”.
The dimension of nature interaction was measured by enjoying the grandeur of the mountains and the landscape when walking on natural trails, observing birds and other species in their natural habitat, and getting to know the native flora. Similarly to the above dimension, females, non-local residents, those not currently working, and those younger than 22 had stronger nature interaction attitudes, and 97.18 per cent of the sample presented positive attitudes on this dimension. On this occasion, the German segment had a stronger nature interaction than the local Canarian segment. The results are only partly confirmed by Cakici and Harman [70] as the authors found that birdwatchers in Turkey were more likely to be young and male, educated but with quite low incomes, and concluded that the relative novelty of this tourism niche might explain this. In our case, females were more common, but our study is not only focused on bird watching.
The environmental concern scale also included the nature connection dimension, including the connection of the human being with nature and the preservation of nature. Results indicate that individuals who are female, non-local residents, under 22 years old, and have lower income exhibit stronger nature connection attitudes, and that 94.45 per cent of the sample presented a positive nature connection attitude. Related results are found in Cavagnaro et al. [71], who, when investigating young travellers in China and Italy, found that young tourists were a very heterogeneous market segment that depended on socio-economic conditions but more intensely on issues related to self-transcendence values connected to nature-related travel motivations such as to be in contact with nature, to experience beautiful natural landscapes, and to see the beauty of the place. The authors concluded that this type of tourist is more open to a sustainable tourism offer.
The obtained WTP figures for diving/snorkelling, cultural trails, active hiking, and stargazing included as activities in the tourist package as well as accommodation type are finally not compared to other WTP figures reported in previous studies, as we consider that these are highly context and methodology dependent. In addition, our WTP results are obtained in terms of the LVs included in the choice model as they are specified interacting with the attributes of the alternatives, and this also represents a significant contribution of this research.

6. Conclusions

This research addresses the role of sustainable tourism activities in Gran Canaria, which constitutes an exciting niche market on an island traditionally dominated by 3S hotel tourism. Like other tourist destinations, Gran Canaria must face the challenge of revitalising tourism activity following the collapse caused by the COVID-19 pandemic. In this sense, promoting nature-based tourism products represents a challenge to achieve more sustainable tourism development.

6.1. Practical Implications

The analysis results provide significant information about preferences and willingness to pay for diverse activities included in a typical active tourism package. In summary, it has been found that a majority of individuals prefer vacation packages that include sleeping in rural houses or tents, active hiking routes, visits to natural spots such as natural pools, and dive or snorkel activities. Despite having an a priori homogeneous sample composition of study participants, our findings reveal significant heterogeneity in preferences and willingness to pay for the various activities under consideration when attitudinal latent factors related to environmental concern are incorporated into the model. Our results reinforce the methodology’s potential for extracting valuable information from study participants while providing interesting managerial recipes that tourism entrepreneurs can use to promote active tourism products as an alternative to the less-sustainable 3S mass tourism.
Results are also valuable for the strategy of the Local Government of Gran Canaria island (Cabildo de Gran Canaria). The Councillor for Tourism of the Cabildo de Gran Canaria, Carlos Álamo, affirms that “at the Tourist Board we understand that it is important to provide Gran Canaria with all possible resources that allow for the sustainable development of the island and, at the same time, serve to promote and strengthen rural or inland tourism in accordance with the values proposed by the Cabildo”. He adds that “Gran Canaria has enormous potential and, with the participation of the business community and public institutions, we have a unique opportunity to promote our destination in a unique way and with the appeal of the attractions and sensations offered by active and sustainable tourism. All in all, ecotourism will be an excellent opportunity to attract those tourists who are looking for a respectful relationship with nature and who have in Gran Canaria an ideal destination to discover and enjoy” [72].

6.2. Limitations and Future Research

Our findings represent a first step towards understanding the demand for sustainable tourism products in a natural setting. As suggested by [16], careful attention was paid to the wording used in the questionnaire to analyse how the attitudes affect the complexity of ecotourism preferences. Nevertheless, this study is not exempt from some limitations, which can serve as areas for future research. First, our study includes two different subsamples of residents and non-residents of very young segments. Second, the context of the case study, represented by a very specific area of Gran Canaria, could be better understood by the segment of residents because they are more familiar with the rural and natural areas of the island. In addition, our results might not be easily transferable to other natural areas where ocean-based activities could not be developed.
Other objectives for future research could include determining preferences for other water and mountain-related activities for tourism product development in other areas of the Canary Islands archipelago. It might also be interesting to look into preferences for other potential customer groups, such as other age ranges and nationalities. Other attitudinal factors, such as the mitigation measures taken by tourists and climate change awareness, could also be worth investigating.
