The intersection of sports and natural forests and green spaces represents an emerging interdisciplinary field with implications for public health, environmental science, and sustainable land management and refers to the variety of cultural ecosystem services demanded by people from ecosystems. This manuscript presents a systematic bibliometric and thematic analysis of 148 publications for the period 1993–2024 identified through Web of Science and Scopus, aiming to evaluate the current state of research on sports activities conducted in natural forest environments. Findings indicated a marked increase in scientific interest of this topic over the past two decades, with key contributions from countries such as England, Germany, China, and the United States. Researchers most frequently examined sports such as hiking, trail running, mountain biking, and orienteering for their capacity to provide physiological and psychological benefits, reduce stress, and enhance mental well-being. The literature analysis highlights ecological concerns, particularly those associated with habitat disturbance, biodiversity loss, and conflicts between recreation and conservation. Six principal research themes were identified: sports in urban forests, sports tourism, hunting and fishing, recreational sports, health benefits, and environmental impacts. Keyword and co-authorship analyses revealed a multidisciplinary knowledge base with evolving thematic focuses. In conclusion, the need for integrated approaches that incorporate ecological impact assessment, stakeholder perspectives, and adaptive forest governance to ensure sustainable recreational use of natural forest ecosystems is underlined.

Although the topic of trampling of alpine vegetation has been addressed by many authors in recent years, many unanswered questions still remain. The generalization of vegetation response patterns to trampling would be valuable, especially for problematic alpine areas, which are unsuitable for large hiking loads. Such an area is the limestone Belianske Tatras, which has been closed to tourists since 1978. Only one trail has been accessible in the area since 1993 as a one-way trail, and since 2008 it has been used as an educational two-way trail. Since there is renewed discussion about making the Belianske Tatras accessible to tourists, we sought answers to the following questions: (1) regenerated communities are more resistant to trampling than the native ones; (2) individual species in different communities react to trampling in the same way; and (3) some species can disappear or become extinct after being trampled. We conducted research in the form of an experiment according to the standard Cole and Bayfield protocol. We trampled three plant communities in 2008, treating them as native, and in 2022, treating them as regenerated. The regenerated communities appeared to be more resistant, although this came at the expense of some species disappearing or becoming extinct as a delayed response. Re-opening the area could be considered. Full article

Trail erosion is a global issue, particularly in mountainous regions, that is largely driven by increased tourist flows and uncontrolled trampling. Our study was conducted in the Bucegi Mountains, Southern Carpathians, Romania, along three of the most frequented hiking trails, each with varying levels of difficulty. Two of these trails cross both the forest and alpine zones, and the other crosses only the alpine zone: Jepii Mici, connecting the Bușteni resort (960 m a.s.l.) to Babele Chalet (2200 m a.s.l.); Jepii Mari, linking Bușteni resort to the National Sports Complex Piatra Arsă (1960 m a.s.l.); and the trail between Babele Chalet and Omu Peak (2505 m a.s.l.). Our analysis focused on morphometric parameters, the volume of displaced soil, and associated geohazards, serving as indicators for assessing the degradation state of hiking trails and their suitability for mountain biking and tourist traffic. The findings reveal a high degree of trail degradation, highlighted by increased trail width, the development of parallel trail sections due to dispersed tourist traffic, areas with abrupt gradient changes, and sections severely affected by erosion, resulting in significant volumes of displaced soil. These factors hinder effective tourist traffic, including hiking and mountain biking, and degrade the mountainous landscape. Conversely, the results can be useful for both monitoring annual trail erosion rates and facilitating tourist access, tailored to individual and group interests, as well as the physical readiness of each tourist, to offer a more pleasurable and sustainable experience.

The accessibility of nature trails for people with motor disabilities and impairments stands as a significant challenge for inclusive tourism. In the present study, we would like to present a review of research, approaches, and solutions to enable people with motor impairments to enjoy nature trails independently or with assistance. The study is conducted from the perspective of public bodies that aim to reduce the accessibility barriers for People with Disabilities (PwDs) by adapting and improving the conditions of the trails and by providing clear and comprehensive information about the difficulties that hikers may encounter on a trail while using a specific aid. The paper initially presents the wide variety of aids for outdoor mobility, including both those to be used independently (i.e., self-propelled wheelchairs that can be equipped with additional small wheels, off-road wheels and/or auxiliary drives) and those that require assistance (e.g., single-wheeled wheelchairs). Then, we shift focus onto the difficulty classification of trails for PwDs, analysing papers and guidelines that tried to define objective evaluation criteria such as the slope, the trail surface, and the length of the sloping sections. Starting from these studies, the paper proposes a synthesis of the different classifications that consider, for the first time, all the aids available on the market, thus filling the gaps of the single studies. In the last sections, we present some national and international guidelines with tailored and practical solutions to improve the accessibility of nature trails and some studies about the inclusive planning that directly involves PwDs, as well as on the need for a better training of tourism service providers. The present work aims to stimulate a debate on the barriers and opportunities related to the accessibility of hiking trails, contributing to making nature a truly accessible experience for all.

Accurate information on trail difficulty is essential for ensuring safety and enhancing the effectiveness of forest-based health and recreational activities. This study examined the physiological responses of middle-aged adults to varying trail difficulty levels across both controlled indoor and natural outdoor walking environments. A total of ten healthy individuals aged 40–50 years participated in walking tasks across three designated trail difficulty levels: Moderate, Difficult, and Very Difficult. Physiological indicators assessed included step speed (SS), step count (SC), rate of perceived exertion (RPE), heart rate (HR), oxygen saturation (OS), energy expenditure (EE), metabolic equivalents (MET), and oxygen consumption (VO₂). As trail difficulty increased, HR, RPE, VO₂, EE, and MET consistently showed upward trends, whereas SS and SC demonstrated significant decreases. Additionally, the outdoor setting imposed generally greater physiological demands compared to the indoor condition, suggesting that terrain complexity and elevation changes amplify physical exertion during real-world trail use. The findings contribute valuable empirical evidence for the design of individualized exercise programs, improved trail difficulty classifications, and the advancement of forest-based health promotion policies.

This study evaluated the floristic characteristics and ecological conditions of disturbed sites within the Baekdudaegan Protected Area by analyzing species occurrence and ecological indices according to the region and disturbance type. A total of 515 vascular plant species were recorded, including rare species, alien species, and Korean endemic plants. To assess ecological patterns, the Naturalization Index (NI), Urbanization Index (UI), and Sørensen similarity index were applied. The results showed that Mt. Seoraksan, Mt. Deogyusan, and Mt. Taebaeksan had relatively high NI and UI values, while Mt. Jirisan showed a comparatively low UI value. Among disturbance types, the hiking trail (HT) type, located in a high-altitude area with limited accessibility, also recorded lower values. Floristic similarity with reference ecosystems was higher in Mt. Jirisan, Mt. Deogyusan, and Mt. Taebaeksan, whereas Mt. Seoraksan exhibited the lowest similarity. The overall similarity between disturbance types was low, and the composition of plant species varied across disturbance types. These results suggest that differences in disturbance intensity, driven by the disturbance type and topographic conditions, influences the floristic composition. The findings of this study can serve as baseline data for developing site-specific restoration strategies for disturbed sites in the future. Full article

Wilderness areas are declining worldwide. A major reason is large-scale forestry activities like logging. At the same time, wilderness offers unique opportunities for recreation in natural and remote environments, enabling communities to gather economic income based on wilderness tourism. An outstanding element of wilderness areas is primary forests. Wilderness is often understood as untouched nature, unchanged by human intervention. For visitors, wilderness resembles a counter-world, enabling them to escape from everyday life. The present study investigates whether forestry activities have an effect on the attractiveness of primary forests for wilderness tourism. This question is answered based on a case study in the Făgăraş Mountains (Southern Carpathians, Romania). The findings show that primary forests are a unique selling point in tourism. Forestry activities are associated with direct (loss of biodiversity) and indirect (change of target group) effects. Forestry activities not only cause changes in forests as a tourism attractor, but also change the attractor’s contexts, by rendering access difficult or by destroying hiking trails. This paper makes theoretical and practical contributions. From a theoretical point of view, it reflects the concept of wilderness tourism and highlights the importance of contexts (i.e., access paths) for the attractiveness of wild forests. From a practical point of view, it highlights the importance of distinguishing various target groups and different degrees of naturalness to maintain a nuanced portfolio of recreational opportunities in wild forests, for example by referring to established management tools like the recreation opportunity spectrum.

The U.S. National Scenic Trail system, encompassing over 12,000 km of hiking trails along the Appalachian Trail (AT), Continental Divide Trail (CDT), and Pacific Crest Trail (PCT), provides critical vegetation corridors that protect diverse forest, savannah, and grassland ecosystems. These ecosystems represent essential habitats facing increasing environmental pressures. This study offers a landscape-scale analysis of the vegetation dynamics across a 2 km wide conservation corridor (20,556 km²), utilizing multidecadal Landsat and MODIS satellite data via Google Earth Engine API to assess the vegetation health, forest disturbance recovery, and phenological shifts. The results reveal that forest loss, primarily driven by wildfire, impacted 1248 km² of land (9.5% in the AT, 39% in the CDT, and 51% in the PCT) from 2001 to 2023. Moderate and severe wildfires in the PCT (713 km² burn area) and CDT (350 km² burn area) corridors exacerbated the vegetation stress and facilitated the transition from forest to grassland. LandTrendr analysis at 15 sample sites revealed slow, multi-year vegetation recovery in the CDT and PCT corridors based on the temporal segmentation and vegetation spectral indices (NBR, NDVI, NDWI, Tasseled Cap). The post-disturbance NBR values remained significantly reduced, averaging 0.31 at five years post-event compared to 0.6 prior to the disturbance. Variations in the vegetation phenology were documented, with no significant trends in the seasonal advancement or delay. This study establishes a robust baseline for vegetation change across the trail system, highlighting the need for further research to explore localized trends. Given the accelerating impacts of climate change and wildfire frequency, the findings underscore the necessity of adaptive conservation strategies to guide vegetation management and ensure the long-term stability and sustainability of vegetation cover in these vital conservation areas.

In recent years, various scholars have called for the development of new forms of cultural tourism aimed at enhancing inland areas. Following this, this paper presents a method for semi-automatically constructing itineraries for cultural tourism, utilizing a geo-dataset of literary quotations, including quotes and itineraries that can offer ideas for new storytelling, envisioning landscapes and cultural references for territorial valorization. This pilot case study focuses on the Dolomite area of the Fiemme and Fassa valleys, a well-known tourist destination also famous for its historic wood production. This study is based on a dataset of geolocated travel reports from 11 different 19th-century authors. These descriptions are classified into Points of Interest (POIs), and the point layer is integrated with a linear layer of the road and path network. Variables such as bus stops and travel time are also considered. The entire process is automated through a script that generates maps of optimal routes for each author, along with corresponding tables of travel times. This method enables the use of this dataset to design and develop specific cultural routes considering different variables. As a result, a cartography of multiple itineraries is proposed, which can serve as a tool for promoting cultural, sustainable and slow tourism development in an alpine inland area. Full article

In human-dominated landscapes, human activities shape prey spatial behavior, creating complex landscapes of risks. We investigated habitat selection of roe deer using resource selection functions in a human-dominated mountain system located in the southwestern Alps, characterized by a high presence of wolves and human disturbance. Our study aimed to assess how the interplay of hunting, presence of infrastructures, and recreational activities in the presence of wolves influenced roe deer spatial responses inside and outside a protected area. We documented that during the hunting period, roe deer increased selection of high-wolf-density areas, with the strongest effect observed during wild boar drive hunts, supporting the risk enhancement hypothesis, where avoiding one predator increases exposure to another, and highlighting the temporary yet significant impact of hunting on predator–prey dynamics. During the period of the wild boar drive hunt, roe deer also showed stronger selection for proximity to buildings, supporting the human shield hypothesis. Protected areas had an increased effect on roe deer avoidance of trails, where hiking and recreational activities are more concentrated. Our findings revealed the complex trade-offs that roe deer face in navigating multiple risks within human-modified landscapes, important for the development of effective conservation and human sustainability strategies.

The expansion of the tourism industry has led to the development of various methods to find optimal tourism paths. However, planning tourism paths in hilly areas remains complex and has specific challenges. Different algorithms have been used to plan tourism paths in flat and hilly terrains, including the traditional Ant Colony Optimization (ACO). Although widely used, this algorithm faces a number of limitations due to its slow implementation and pheromone update rules. This paper introduces a new approach to overcome these limitations. It presents a method for efficiently optimizing tourism paths in hilly areas based on an improved version of the ACO algorithm. The limitations of the traditional ACO and the Genetic Algorithm (GA) are addressed by improving pheromone updating techniques and implementing new initialization parameters. This approach provides a comprehensive and efficient method for planning hiking trails in hilly regions, considering dynamic tourism objectives such as temperature, atmospheric pressure, and health status. The proposed method is implemented to develop tourist routes in the hilly Jebel Marra region in Western Sudan. A comparison is provided between the effectiveness of this approach and the GA and traditional ACO algorithms. The advantage of the proposed approach is illustrated by results showing an optimization time of 0 points and 27 s compared to 0 points and 45 s and 0 points and 40 s for GA and ACO, respectively.

Background and Objectives: Accurate hiking time estimate is crucial for outdoor activity planning, especially in mountainous terrains. Traditional mountain signage and online platforms provide generalized hiking time recommendations, often lacking personalization. This study aims to evaluate the variability in hiking time estimates from different methods and assess the potential of a novel algorithm, MOVE, to enhance accuracy and safety. Materials and Methods: A cross-sectional analysis was conducted using data from 25 Italian loop trails selected via the Wikiloc platform, considering user-uploaded GPS data from at least 20 users per trail. Real-world hiking times were compared with estimations from Komoot, Outdooractive, mountain signage, and the MOVE algorithm, which incorporates individualized biological and trail characteristics. Results: Significant discrepancies were observed between actual hiking times and estimates from Komoot (ΔWK: −48.92 ± 57.16 min), Outdooractive (ΔWO: −69.13 ± 58.23 min), and mountain signage (ΔWS: −29.59 ± 59.90 min; all p < 0.001). In contrast, MOVE showed no statistically significant difference (ΔWM: −0.27 ± 65.72 min; p = 0.278), providing the most accurate predictions. Conclusions: Current hiking time estimation methods show substantial variability and inaccuracy, which may pose safety risks. MOVE demonstrated superior accuracy, offering personalized hiking time predictions based on user-specific data and trail characteristics. Integrating such advanced tools into outdoor activity planning could enhance safety and accessibility, particularly for individuals with chronic conditions. Further studies should explore integrating real-time health data to refine these tools. Full article

The dynamics of territorial planning, the management of its tourism products, and the monitoring of demand flows and their impact on the territorial structure (social, economic and environmental) require tools that support the acquisition of reliable quantitative data, as far as possible in real time, that are easy to manage and allow immediate analysis. In the case of structures and equipment anchored in the nature tourism segment, in particular hiking trails, in addition to determining the demand indices in a network of hiking trails and understanding their territorial and temporal dynamics, the data collected through automatic counters is a crucial tool to support territorial management and evaluate the patterns and flows of tourist demand. Based on these assumptions, this research seeks to analyse demand data observed on eleven hiking trails in the Historic Villages of Portugal, collected through automatic monitoring systems (counters). In four years, between 2020 and 2023, the trails analysed generated a demand of almost 190,000 passages, which translates into an annual average of 47,500 passages in the tourism product “Historic Villages of Portugal” (more than 4800 passages for each trail), mostly in the spring and autumn months, mainly on weekends.

Tourism and recreation development in naturally valuable mountain areas is a complex issue. On the one hand, it has a positive impact on the physical and mental health of modern society, especially after the COVID-19 pandemic. It also contributes to the economic growth of local communities, for which financial revenues from tourism are important sources of income. However, exceeding the limits of tourist absorption and improper trail management can lead to natural environment and landscape degradation. The Carpathians are marked by a dense and diverse network of tourist trails that can have an impact on biodiversity, which is often unique in this European region. The aim of the study was to determine tourists’ preferences in terms of the attractiveness and development of the mountain trails of the Carpathian region. The research was conducted using a survey on 10 main hiking trails in the Beskids. The results were compared with the inventory carried out in the field based on tourist values. The results highlight the possibility of achieving a balance between the use of tourist trails and the protection of the natural and cultural environment. Our results can be useful for the sustainable tourist management of mountain landscapes, linking nature conservation and recreation requirements. Full article

Forest trail difficulty levels must be investigated to promote their safe usage. However, exercise-based physiological changes are difficult to estimate in a forest environment. Hence, studies comparing indoor and outdoor environmental activities are required. We aimed to investigate the physiological traits associated with different usage grades of national forest trails in the Republic of Korea. We conducted both field and indoor experiments to measure different variables of 20 healthy participants aged 40–50 years to evaluate the exercise intensity and physiological effects of hiking on these trails. Significant variations in physiological responses were observed based on trail difficulty, with the highest heart rate and energy expenditure recorded during the most challenging uphill segments. Specifically, the heart rate increased from 115.4 ± 13.7 bpm in easy segments to 140.3 ± 15.6 bpm in difficult segments, whereas energy expenditure ranged from 404.1 ± 112.2 kcal/h to 518.1 ± 131.0 kcal/h. This study highlights the importance of considering both objective trail difficulty and users’ physiological reactions, including perceived exertion, to enhance user safety and optimize the health benefits of national forest trails. These findings provide essential data for developing comprehensive exercise programs and improving the national forest trail usage grade system. Full article
