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.

We are at the top of Prewitts Knob, so when there is ice or snow the road may be treacherous and we will be closed for your safety.  Please call (270)773-3377.

The Cave is closed until Dec. 5.

No tours will be conducted from Nov. 20 to Dec. 5. We’ll be conducting clean up and maintenance on the cave.

One of our reviews:  Beautiful Close-up Experience!

“This cave blew me away from my very first steps into the dramatic entry way. The walkways and lighting are beautifully done throughout the cave, with amazing features at every turn. Our small group was privileged to have one of the owners as guide. His commentary reflected the joy and pride he has in this special place. I’ve toured several caves, including the nearby bigger one, but none has captured my heart like this one. There’s so much bang for your buck to be enjoyed here!”
