Dutayeon Falls (두타연) is located on a branch of the Suip Stream (수입천) that flows through Geonsol-ri (건솔리), Bangsan-myeon (방산면), which is north of the Civilian Control Line. The amount of water that flows into the pond is limited, but the surrounding forest provides superb and almost primeval scenery, while the pollution-free waters offer a habitat for Korea’s largest lenok population. Lenok are a species of freshwater fish under the official monitoring and control of the Korean government.
A 20-meter screen of flat rocks surrounds the pond and the east wall features a 10-meter square cave, the floor of which is imprinted with the shape of a comb and horse harness.
