Ecotourism has problems such as accidents caused by participants participating in tours that are not suitable for their physical fitness, and overtourism. Digital archiving of eco-tour route trails is considered useful for accident prevention by visualization of information on difficult spots along the trails, as well as for quantitative and continuous monitoring. In this study, we measured the trail to Kura Falls on Iriomote Island using LiDAR, and selected difficult spots based on the minimum height of each 5m section and the calculated difference of the 85th percentile value from the minimum. In addition, we calculated and visualized the difference between the two periods, and revealed changes in fallen trees, etc. of about 0.15m. The application of LiDAR to the digital archive of mountain trails showed that it is possible to select difficult areas and to conduct primary screening for natural environment monitoring surveys.
