Namcheongyegok Valley is located on the northern side of Sobaeksan National Park. The forest is preserved quite well because the valley is located deep within the mountain. Freshwater fishes can be found within the clear water of the valley. The lush plants and clear water in summer and the fall foliage in autumn present a beautiful view. Follow the small trails to find the Namcheon Campground, where one can enjoy camping deep in the forest.
