Daegeumgul Cave (대금굴) 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.Sections of Daegeumgul Cave● Artificial Tunnel Section: The 140-meter stretch from the entrance of the cave is a man-made tunnel and the route for the monorail.● Waterfall/Platform Section: There is an 8-meter high, natural waterfall and the platform for the cave monorail.● Stalactite Section: This section contains various subterranean features, such as rim pools, stalactite pillars, bacon sheets, cave shields, cave pearls, deformed stalactites, and helictites.
