Dongmakgol (Naesan-ri) is a valley that spreads over a large area of 571,211 m2 with clear water flowing in twists and loops. The area surrounding the valley combines with strange rocks, bizarre stones, and natural forests, adding mystery to the natural scenery. As the water levels are low in most areas, there are almost no accidents involving children. It is gaining attention as a tourist destination for families. It is also fun to go bamboo fishing here.

In Yeoldugaeul Valley, a cliff with rocks of strange shapes that connects Choseong-ri, Cheongsan-myeon, Yeoncheon-gun with Deokdun-ri, Sinbuk-myeon, Pocheon-gun, and a clear valley join hands to create a scenic view. The attractions such as Seonnyeobawi Rock, Mujangso, Boanso, Manjangbawi Rock, Pyeongbawi Rock, Dorasso, Dolmukso, Bongbawi Rock, Ssangmuso, and Yongsugolso spread out over 4 km. In the old days, when there were no bridges, people had to cross 12 creeks (mountain creeks) to travel from Beopsu-dong to Deokdun-ri, giving it its name. The valley is now home to five bridges, making it convenient to travel. However, the name “Yeoldugaeul Valley” still remains. Sinbuk Hot Springs in Pocheon, which was designated as a hot spring district in December 1992, is located nearby.
