The caverns are lighted with special colored lighting, the designs and textures are pretty amazing for occuring naturally. It is kinda damp and cool in there, 58 degrees year round. You are guided along by a tour guide who explains different aspects of the cave, some areas are narrow and the celilings are low, but they do provide you with handrails at places that are difficult to get to. There is an underground lake that they've got no idea how deep it is or how wide it is but it is fresh spring water that seems to filter itself and continuously stay at the same level.
It is not too expensive, don't remember exactly how much but if you are looking for a way to kill some time this is as good as any.
