Yongchu Gyegok Valley is located in Mt. Daeyasan and it is the unique place where the water does not dry up throughout the year. Mt. Daeyasan, which is located in Wanjang-ri, Gaeun-eup, Mungyeong-si, Gyeongsangbuk-do, is formed of sharp peaks and all different types of Giamgoeseok, and the waters that flow through the valleys do so all year long. It borders Chungbuk Goesan-gun and Gyeongbuk Mungyeong-si, and is located in Mt. Daeyasan (931m). The three-tiered Yongchu Pokpo Waterfall, located in Yongchu Gyegok Valley, is a legendary pace where two female dragons flew up to the sky. Yongchu Gyegok Valley is divided into Upper Yongchu and Lower Yongchu. The place where the water falls out of the granite foundation down to where the heart-shaped pond is, is Upper Yongchu, and below that point is Lower Yongchu. On either side of Yongchu, there are two large markings on the granite boulders, which are said to be dragon scale markings, made as they rose up to the sky. Even when other places are suffering from droughts, water flows abundantly here. Above the Yongchu Waterfall, past the base rock about 20 minutes away, you will reach Wolyeongdae. It was named after its breathtaking view of the moon reflected on the water flowing through the rocks in the valley below. Near Yongchu Gyegok Valley there is the Seonyudong Gyegok Valley, also called Seonyu Gyegok (a place of 9 sceneries) where the Okgyesu River runs through two great rocks, which look as if it is artificially split.
