There is also a very nice campground and visitor center, while I have really enjoyed.
The original cave entrance was in a sinkhole and was very tiny. This opening was cut through for visitors. Most unusually, this is the only cave I have ever seen that is completely wheelchair accessible, which was quite a feat in its construction because they wanted to move and damage as little as possible.
This photo shows the walkway which has built-up sidewalls. You may not touch anything in the cave as well as the tops of these walls. The whole walkway is washed down every night to remove any dirt, skin cells, or other contaminants brought in by humans that could harm the cave.
These are called soda straws because they are so thin.
Hopefully, they have done things right when they opened this cave to the public and we will not destroy it as we enjoy it.
