Daegeumgul Cave is believed to be as old as Hwanseongul and Gwaneumgul Caves located nearby. The entrance to the cave was not exposed until 2003 when an excavation project revealed the entrance, 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. You can also visit the ecological park, built in harmony with the natural environment of the cave and the surrounding area. Also, take Korea’s first cave monorail 140 meters deep into the cave, and be sure to stop by the Visitor Centre where you can learn about the significance of natural caves. Because of its fascinating features, Daegeumgul Cave is fast becoming a popular tourist attraction in the Donghae area.
