These two caves are open to the public as part of the Hallim Park tourist complex which also includes gardens, aviaries and a recreated traditional village. The caves are roomy with paved walkways.
The caves were formed by the eruption of Mt. Halla, together with over 20 other caves in the area. Connected they were about 17 km long, which would make them one of the longest lava tubes in the world. However, the caves are not connected any more, as they are rather old. There is even a theory that they may have been once below sea level, as there are fossilized seashells, including abalone shells, found in the caves.
The most unusual feature are calcite speleothems, stalactites, stalagmites and soda straw, which are unusual in a lava cave. The lava does not contain limestone, soe there must be a different source. A possible solution is the nearby sea. If the cave once was below sea level, there might be limestone rich biogene sea sediments above.
A almost typical sight for a lava tube, still seldom tio see, are lava stalactites. When the lava still flows, molten rock which swashed at the ceiling drops back down and forms stalactite like structures. When it slowly solidifies, it keeps this form.
