Ohio's Largest and Most Beautiful Cavern

Tours take guests through two different parts of the cavern. The Historic Tour begins at the site of discovery and includes the area that was originally explored from 1897 to 1925. The Natural Wonder Tour takes guests on a 1 mile walk through parts discovered after 1925. It includes the largest stalactite in Ohio, The Crystal King, along with many other marvelous formations and colors. The Winter Tour is the only tour offered from October 1st through April 30th. It is a hybrid tour, showing guests highlights from both the Natural Wonder and Historic tours.

What Are People Saying About Us?

Do the combo pack; it is the best way to see the entire cavern. One is mostly history and the other is mostly formations but each gives you a different perspective. This is one of the most colorful caverns I have ever been in; it really is neat. — Amie S.
Took the Natural wonder tour with a group on a 4H trip. Kids enjoyed the sites, staff was very friendly and tour guide was very good at keeping things interesting for the kids. Overall it was a good experience. — Daniel C.
