Chilseongyegok Valley is the most beautiful valley in Jirisan Mountain, and is one of the top three valleys in the nation, along with Cheonbuldonggyegok Valley in Seoraksan Mountain and Tamnagyegok Valley in Hallasan Mountain. The 16-kilometer valley stretching from Uitan of Macheon-myeon to Cheonwangbong Peak is characterized by very tough topography but beautiful scenery and is the only remaining primeval forest of Jirisan Mountain. It is also dotted with seven waterfalls and 33 ponds. The hike becomes more difficult as the trail enters the valley. Because the valley has taken many lives, some people call it "The Valley of Death." For that reason, visitors must apply in advance and hike with a guide. The trail in Chilseon Valley is a 9.4-kilometer course from Chuseong Village in Macheon-myeon to Cheonwangbong Peak, which does not follow the natural valley, due to the valley's steep and dangerous features. Starting from Chuseong Village, the trail passes Yongso Pond, Jujiteo Site, Chuseongmang Rock, Seonnyeotang Pond, Ongnyeotang Pond, Biseondam, Chilseonpokpo Falls, Daeryukpokpo Falls, Samcheungpokpo Falls and Mapokpo Falls, all before reaching Cheonwangbong Peak.
