Daegeumgul Cave is believed to be as old as Hwanseongul and Gwaneumgul Caves located nearby. The entrance to the cave was exposed during an excavation project, and after a long preparatory period, the cave was opened to the public. This newly opened, well-preserved cave is filled with limestone features such as stalactites, and a considerable amount of water flows through the cave, creating waterfalls, both large and small, along with numerous ponds.
