Would visit again--not a huge cave, but really interesting. Lots of drippy stalagmites/stalactites (?) and underground water system. We were the only ones there when we visited and had the cave to ourselves. It's supposed to be a self-guided tour with audio headphones, but we didn't use them. It's 54 degrees all year long, so take a jacket. Was $7.50... More

This was a nice experience sooooo much better than the mystic cavern in harrison where I had to climb over 100 FEET OUT OF THE CAVE!!! The manager and staff was so much nicer at the onyx I had such a better experience at the onyx if your coming from harrison this cave took me like 50 mins more and... More

self guided tour with headphones educating you about the cave and its history at various stops along the way. very reasonably priced,a bit of a walk and not handicap friendly,very cool in the summer,we enjoyed this place.I recommend this cave.

The cave is exhausted. It's nearly dead. Over commercialized through the years. I love caves but not this one.

Fun cave experience. It seems that with each corner or section of this cave brought oohhs and ahhhs from the entire crowd. I took many pictures to remind myself of the amazing wonders that exist because of our Creator.

As much as I wanted to love it, I was a little disappointed. The owners, staff and giftshop were delightful, but the actual cave was disappointing. It's neat that they have a self guided tour, but it has just been over traveled. All of the natural moisture has dried up, I assume thanks to all of the hands touching everything... More

Owned and ran by a sweet old lady. This place is open year round. Been twice and still very interesting. No guide so you can set your own pace. Watch your head!

We saw a sign for the Onyx cave and decided to give it a try! It was so cool and very informative. The owner was very nice and made us feel at home. The cave is gorgeous and informative.
