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.

We looked into going here after reading about how beautiful it was. When speaking with guide at Onyx cave she said the "crystal Onyx cave" closed awhile ago and they still get people confusing the two.
