Easy hike, really nice guides, our grandkids love going there. The cavern has some interesting formations and is right next to I-35, so very easy to access

Really great tour. There was more I wanted to see in an extended tour, but we had the little kids with us and it will have to wait til next time.

Beautiful formations and careful attention to lighting make this a special cave in central Texas. Discovered in the 60s by spelunkers lowered by road building equipment, this cave has a lot more of those delicate formations we expect to see.

Took the family here. 4 girls ages 5-14. Everyone enjoyed the tour. Enough history and science to keep adults interested and plenty of fun facts for the kids. Nice and cool underground, so it was a relief from the Texas heat. We would go back

We've visited Inner Space Caverns on several occasions over the last 15 years, often taking out-of-town guests for the experience. The caves are really a fascinating piece of local history and the tours provided are quite informative and educational. It's like a 'mini Mammoth Caves', right in our own backyard here in Georgetown. I highly recommend a visit!

Caverns are odd things with unique formations. The evolution of things like how "soda straws" are created is explained on this informative tour. Tour guides are young and energetic. They have names for many of the bizarre structures dotting the subterranean walking path. If you want to be adventurous sign up in advanced for the 4 hour off the beaten... More

Stopped here with the family, very interesting and beautiful. The cave has other more extensive adventures but you need to be at least 13 years old. Great place to visit

When it is 100 degrees plus, Inner Space Cavern is a great place to go! It is a small cavern, but has some beautiful formations. I have lived in Georgetown for 27 years, and it is a great place to take out of town company - especially in the summer when temperatures are so high - nice and cool in... More

If you're interested in caves or have never seen a cave then it's definitely worth a trip. The caves were big, easily accessible (at least in the Adventure Tour) and beautiful. Our guide Tony was very funny, patient and knowledgable. He had great stories about the cave formations. They show you total darkness. The caves are warm inside all year... More

If you've visited any of the east coast caves in Virginia or Kentucky you will be disappointed in this one. It was surprisingly drab inside - I suppose the colors underground reflect the palate on the surface- various shade of beige. The story behind the discovery and development of the cave is interesting and probably unique in the world of... More
