Inside the cave, if you are in a small tour group, you may see a tiny, opaque, cave-adapted species of springtail, an insect that thrives in the cool, damp environment. It is recommended that most people stay for at least two days, to be able to leisurely experience all of the park. There is no park entrance fee Spring and fall weather are the most variable with cool, damp days alternating with dry, warm ones.
Summers are usually sunny, hot, and dry.
Winters are usually mild with little snow, but sub-zero temperatures can be expected.
