This place is great! The park rangers we so funny, knowledgeable and kind- of your follow the rules you will have a wonderful time! There is a lot of walking in the cave and most of it was pretty easy but if you are sensitive to walking wear good shoes and you will be fine. Right now it's a self guided tour which means you just walk and look, however they have rangers all over the place answering all of your questions (and they loved talking to us). Outside of the cave is beautiful hiking and some paved bike trails. Enjoy your time there!
