Yanggu County strung this eco trail between its first sight, the arboretum, and its ninth, Gwangchi Valley. End to end it is 11.6 km, more than half a day on foot. Old signposts were replaced and safety ropes added on rough spots in 2025, so it works as a Daeamsan-flank walk when Yongneup slots are full. The Gwangchi end is a creek valley, best in summer for the sound of water.
