Relatively newly discovered by native villagers, the cave is extensive and unaltered, full of narrow, maze-like passages, and countless stalagmites. It is not advised to go without a guide, a crash helmet and a flashlight. The entrance is accessible only by boat and the whole trip would take approximately 2 hours. Near the exit of the cave, there is a mud bath onsen. However, given that the cave is not fully explored, the absence of certain security measurement exists. Thus going in alone is not recommended especially after 16h.
