Drove by entrance a few times on our way to Glasgow and decided to stop. My wife and I enjoyed the tour and our guide did a fantastic job. It was educational and fun. Definitely worth checking out.

A smaller cave than Mammoth and Diamond, but just as beautiful. And the young man, who was our guide, was great !! Thank You !! Don't miss this cave, it is so worth it.

New owners are renovating. This cave is the most beautiful in the area, so any improvements for tours can only enhance the experience. When it reopens, I hope you will visit! Not to be confused with Onyx Cave nearby.
