Dosolgyegok Valley is located in Seonunsan Mountain in the Gochang-gun district. Seonunsan Mountain, which is also called Dosolsan Mountain, is known for its thick forests and intriguing rock formations. Along the valley, there are many interesting sites such as Jinheungdonggul Cave, Yongmundonggul Cave, Nakjodae Overlook, and Cheonma peak. Dosolgyegok Valley is also famous for being very deep, where the mountain and water fight each other and whirl around in a yin & yang shape. The green forests in summer cover the valley beautifully, and the red leaves and white snow decorate the area in fall and winter.
