When you visit us you will find a wealth of fun and interesting things to do!

We have ample parking and free picnic grounds.

We welcome school groups and tour buses.

Experienced guides will escort you on the 55 minute tour of Mark Twain Cave where the walkways are level and smooth and there are no steps. Because of the natural state of our cave (narrow passages, etc.) it is not wheelchair accessible.

Our cave stays a constant 52 degrees year round! (A light jacket or sweater is recommended on the tours.)

Cameron Cave is a 1 hour and 20 minute tour and several people will carry lanterns as the cave is very nearly like it was first discovered in 1925.
