Various methodologies have been proposed to evaluate the suitability of forest trails to be constructed as hiking trails, but they can be costly and require relevant knowledge in analyzing digital information through a high-throughput dataset. Therefore, there is a need to come up with a simple method to obtain first-hand information on the trail condition, particularly considering the aspects of safety and suitability to hikers, using both on-ground and aerial observations. In this study, we introduce a new assessment approach to analyze and select old forest trails to be reconstructed as new hiking trails. This is useful for park managers who prioritize safety, comfort, and aesthetic features of the recreation site for their visitors. Trail condition assessment was carried out along the trail whereby a 2\u00d72 m sampling plot was constructed at every 100 m. Aerial drone survey was conducted to produce an ortho-mosaic that revealed the percentage of exposed trail from above. Potential phytotourism products and scenic spots were identified and recorded for their locations along the trail to promote the aesthetic value of the recreation site. A strength distribution plot was prepared based on the trail condition, canopy coverage, and aesthetic features along the trail that were categorized using three altitude ranges (n \u2264 150 m, 150 &lt; n &lt; 250 m, n \u2265 250 m a.s.l.). This is to assess the trade-offs in safety, comfort, and aesthetic features along the trail. The development of this methodology offers a direct and cost-effective, yet informative approach to evaluate the quality of a potential hiking trail, thus could effectively aid in the promotion of nature-based tourism.<\/jats:p>","DOI":"10.3390\/ijgi9040221","type":"journal-article","created":{"date-parts":[[2020,4,7]],"date-time":"2020-04-07T03:58:39Z","timestamp":1586231919000},"page":"221","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Assessing Safety and Suitability of Old Trails for Hiking Using Ground and Drone Surveys"],"prefix":"10.3390","volume":"9","author":[{"given":"Shiou Yih","family":"Lee","sequence":"first","affiliation":[{"name":"State Key Laboratory of Biocontrol and Guangdong Provincial Key Laboratory of Plant Resources, School of Life Sciences, Sun Yat-sen University, Guangzhou 510275, China"}]},{"given":"Chengju","family":"Du","sequence":"additional","affiliation":[{"name":"College of Forestry and Landscape Architecture, South China Agriculture University, Guangzhou 510642, China"}]},{"given":"Zhihui","family":"Chen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Biocontrol and Guangdong Provincial Key Laboratory of Plant Resources, School of Life Sciences, Sun Yat-sen University, Guangzhou 510275, China"}]},{"given":"Hao","family":"Wu","sequence":"additional","affiliation":[{"name":"Shenzhen Dapeng Peninsula National Geopark, Shenzhen 518121, China"}]},{"given":"Kailang","family":"Guan","sequence":"additional","affiliation":[{"name":"Pubang Landscape Architecture Co.
