Chilseon Valley (칠선계곡) of Hamyang is the longest and largest valley in Jirisan Mountain (지리산). It is one of the top three valleys along with Cheonbuldong Valley of Seoraksan Mountain and Tamna Valley of Hallasan Mountain. The 16-kilometer valley stretching from Uitang 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 deeper you walk into the valley, the tougher it becomes to hike. Because the valley has taken many lives some people call it ‘Death Valley’. For that reason you can hike Chilseon Valley only after obtaining permission and must first take a 9.4-kilometer course from Chuseong Village of Macheon-myeon to Cheonwangbong Peak, which lies far from the actual valley. If you begin in Chuseong you will run into all of Yongso Pond, Jujiteo, Chuseongmang Rock, Seonnyeotang Pond, Ongnyeotang Pond, Biseondam, Chilseon Falls, Daeryuk Falls, Samcheung Falls and Ma Falls, until you reach Cheonwangbong Peak.
