Brought my granddaughter there & she loved every minute of the experience. She asked so many questions, nobody else hardly could get a word in egdewise. Then of course, had to get some rocks & pretty stones at the store there. Great for children especially.

We did the basic level tour (guided, no serious climbing/caving) and had a fun experience. Our tour guide was knowledgable and funny, and gave great insight into the history of both Austin and the cavern itself.

This was the last stop of our family vacation. We had also visited the Natural Bridge Caverns earlier on vacation. The caverns seemed cooler than NBCs. This was a good visit, but if you were going to do one, I would do Natural Bridge. That...More
