Dutayeon Valley is located north of the Civilian Control Line, requiring advance reservation through the Yanggu-gun Office website as well as filling out admission information at the Dutayeon Gallery before entering the area with a guide. The valley has a waterfall located along Sataecheon Stream where it merges with Suipcheon Stream. The water falls into a plunge pool, which has also carved out a deep cave in the bedrock at the base of the waterfall.
