Jeollabuk-do(Gochang-gun)
Dosol valley is located in Mt. Seonunsan, Gochang-gun district. Seonunsan Mountain, which is also called Dosolsan Mountain, is known for its thick forests and intriguing rock formations. Traveling along the valley, one can come across many interesting sites such as Jinheung cave, Yongmun cave, Nakjodae, and Cheonma peak. Dosol 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 the summer cover the valley beautifully, and the red leaves and white snow decorate the area in the fall and winter.
