온달동굴 (Ondaldong-gul, Ondal Cave) is located below Ondal Castle and named after it. On ancient maps, like Dongguk Yojiseoungram, the map of east nations, it is also called Nam-gul (South cave) or Sansung Gul (Castle cave).
The cave is entered through a portal which is 8 m high and 15 m wide. The tour includes the main branch, which is 312 m long, and a side branch which is 283 m long. Six chambers of various size contain an abundance of beautiful speleothems. The cave has a cave river, which springs from the cave and is said to be the underground drainage of nearby Dragon’s Lake (Yongso), located in the Kagok-myon.
Above the cave on top of the hill is the Ondalsanseong Fortress. It is said to be from the 7th century and is from the Goguryeo Era (37 BC-668 AD). Both cave and fortress are the place where every year in October the Ondal Culture Festival is held, in memory of the legendary love story between General Ondal and Princess Pyeonggang. If you do not intend to visit the festival, you should avoid the cave at that time because it is very crowded.
