The guide walked us through pretty quickly. It was interesting information, but consider it a "been there, done that" experience now.

We took our Boy Scout Troop for the overnight cave experience. It was expensive and worth the money. While there were other groups, we hardly saw them. Our guide showed us through the different crawls around the rocks. We came out exhausted, dirty and covered with clay. We loved it.

Stopped here on a whim after a family reunion. We had never been on a guided cave tour before so it was all new to us. It is better than watching the discovery channel.

I've been on several cave tours around the country including mammoth caves but have to say this one is my favorite, the "sea" at the bottom were we rode a glass bottom boat which was awesome and the fish were biting. I highly recommend visiting the place if you are in the area.

This is one of those see it once and it is awesome - been there done that kind of attractions IMHO. I especially loved the glass bottom boats and the trout. Lots of history. Just a fun time. Worth the trip. I also think the admission is a bit pricey, but wasn't disappointed after spending it

I've been here a few times, always fascinating! They do a good presentation of a very interesting place. Caves are much the same but this one has a big lake in it. Quite enjoyable.

Yes, there was a cave (cavern). Poorly lit. Only a few highlights (where the guide points out a formation and tries to make it into some kind... More

The two boys with us seemed to enjoy this adventure. It is very awe inspiring and I could see they were imaginging finding this cave and exploring on their own. They need to invest in some mics for the staff because if you are with a large group you have no idea what the guide us saying. The guides need... More
