Duerin-bawi 드린바위 is 130m high and 100m wide. It was rst developed in 1975. In May 1998, it was redeveloped with the addition of ve routes, including a couple of aid routes. This crag looks a bit creepy. It is dark granite and the climbs vary from face, slab, crack, and overhanging routes. This is a good place to train for big-wall expeditions.
