Crystal Onyx is one of Kentucky’s premier show caves with spectacular beauty throughout. Our cave, located on Prewitts Knob is a living, growing cave. You will be walking among a vast and diversified array of formations up close throughout the cave on your one hour, one half mile tour. Tour group size is small with a comfortable pace and plenty of stops so you can see all of nature’s wonders, take pictures, relax and enjoy.
Your adventure begins outside with a short walk to one of the many sink holes and caves on our property. You will descend down safe concrete and steel steps into a well lit speleothem rich cave. The meandering trails have recently been renovated with groomed crushed limestone, new steps and handrails. The average temperature in the cave is 58 degrees F or 14.5 C. Crystal Onyx is family owned and operated with a laid back approach and unscripted tours.

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!”
