Tours run every 30 minutes 7 days a week from 9am-4pm. Our tour guide was friendly, enthusiastic, and well versed in the historical and geological features of the caverns. You could tell she really enjoyed teaching others about the caves and the really rubbed off on everyone else. (I wish for the life of me I could remember her name, I’ll do some research and get back to you!)
The cost is $10 for a tour that lasts about 30 minutes. Along the tour you will run across a mineral spring with running water. We were told that it was drinkable and I was one of the few who proved it. It’s probably some of the freshest natural water I’ll ever drink.
If you end up arriving between tours, there is a fairly large gift shop with crafts, books on being/cooking like a redneck, and a small fast food kitchen (all with lower than expected prices). You can take a look at some of my better pictures after the jump and the rest here.
