After passing Okgye Village from Yeoncheon Lohas Park and walking along the third course of Peace Trail, a forest hiking trail passing through Cheonghwasan Mountain and Manggoksan Mountain will emerge. The section is about 4.5-kilometers-long, and narrow paths of the hill are used. In particular, there is a small narrow path called a Path through Speculation (Sasaekui Osolgil) in Manggoksan Mountain and an octagonal pavilion at the top of the sports park, allowing you to easily escape from your daily thoughts.
