Geumdanggyegok Valley, located upstream of the Pyeongchanggang River, is a gorge between three different districts of Bongpyeong-myeon, Yongpyeong-myeon and Daehwa-myeon, just west of Geumdangsan Mountain (1,173 m). Geumdanggyegok Valley is an impressive site with sections of both gentle and fast flowing valley waters. From late March through April full-blown azalea covers the mountainsides and valleys providing visitors with a refreshing spring scent.

To reach Geumdanggyegok Valley, travel down along the Pyeongchanggang River from Jangpyeong or trek up the valley from Anmi Elementary School. Coming down to Pyeongchang-eup from Daehwa-myeon area, visitors will encounter an intersection called, “Saechugeori”. The intersection has two parts: Sanganmi and Haanmiri and a sign indicating the Geumdanggyegok Valley entrance. Across the valley, odd-shaped rock formations and cliffs appear one after another along the river. The area is a native habitat for a species of otter (Natural Treasure No. 330) and a favorite spot for catching catfish.
