We took the Daily tour - an entertaining hour-and-a-half, three-quarter mile underground hike out and back.
However, the caverns offer some speciality tours that I would love to return and take. For children over 11, it has the Wild Cave Tour which goes into less accessible places and requires helmet, knee pads and flashlight. There is also an evening paranormal tour once a month. Supposedly the cavern is haunted, and the evening tours occur at night and sound pretty fun and spooky!
The tour fee is $12.99 for adults and $7.99 for children. In addition to the tour, the tour leaders do accept tips, so bring a few spare dollars to thank your tour guide when you leave.
No food or drink is allowed in the cavern, but you may bring in a water bottle.
If you are looking to make a whole day of it, Inks Lake is just a mile or so down the road, and a fun place to spend the rest of the afternoon!
