Crystal Onyx Cave

We're not Mammoth, but we are Spectacular!

View of the first landing.

Crystal Onyx Cave is one of the most beautiful caves in the USA. The lighting is exceptional and designed to show our beautiful formations. The cave was discovered by prehistoric people about 680 BCE.  Rediscovered by modern man in 1960.  Come visit us for a one hour tour.  We are under the cell phone towers on Prewitts Knob. We also have a gift and mineral shop stocked with neat stuff.

Don’t worry about storms, this cave won’t flood because we are at the top of the knob. We stay open.

Great News:  The cave will remain open until November 11th.
