We live right by these caverns but we don't tend to take visitors very often because the caverns are just average compared to some others in the state. They are also hot and way too expensive, again compared to other caverns in the state. The archeological finds in this cavern are unique and interesting and, last time we were there,... More

I have been taking my First Grade class to Inner Space for the last nine years and every year the kids say it's the highlight. There is so much th see and learn in the cave but also the mining above ground is so exciting as they uncover treasures in the bag of sand. It's a great time for all.

Enjoyed visiting Inner Space when we first moved to Georgetown. Have taken out-of-town visitors there several times. Our grandson was fasicnated when he had the opportunity to go "down under the interstate" to see such beautiful formations. A gift to our community.

Inner Space Caverns were very neat to see. I was highly disappointed that the wait time for a hidden passage tour was over an hour and a half so we were unable to do that tour. Other than that, I would definitely recommend going at least once if you are in the area.

What a beautiful cavern! My husband and I went on the Adventure Tour a few weeks ago and loved it. Our tour guide was fun and informative, she even turned the lights off for us so we could all experience complete darkness for a bit! We also saw a few tiny bats sleeping (they were adorable, by the way). I... More

I enjoy caves and have been in a few. However, this is the first cave I've been in that didn't set off my internal panic alarm, because there were no spiders or cave crickets (which are very spider-like to me). The only creatures I spotted were bats and when I asked the guide about others, the only other critters in... More

We visited about 1 PM and had just missed a tour, so were placed in line for the next your (tour 12). Our guide was Charles (I think?). He was so awesome! He saw that there were quite a few kids in our group and he made the tour more about him. We didn't mind as we wanted to just... More

We were lucky enough to get a great tour guide. She was fun, knowledgeable and friendly (Bailey?). The caverns were beautiful and full of cool photo ops. What an experience! This is great for the history buff, science geek or those just wanting to explore Texas!

We did the "adventure" tour - 2 adults and a 9-year-old. The tour was easy to do, and kept us all entertained. The cavern itself is pretty and you go into several "rooms" with different sizes and types of formations. This was an easy drive (about 3 hours) from the DFW area. It gave us chance to explore a new... More

We took our 13 and 8 year-old sons on the Hidden Passages tour and they absolutely loved it. Definitely worth the extra few bucks! They felt cool carrying their flashlights and "exploring" the caverns. We even got to see 5-6 bats hanging from the ceiling! There were a few places where you had to duck out a little, but it...
