This is a GREAT activity for kids and adults every time. The caverns are beautiful. Don't skip the opportunity to sift sand for beautiful rocks.

Nice cave right off I-35 in Georgetown. The Cavern was discovered in the early 60's due to road work on 35. Seems like that never ends. Our tour guide was Lauren and she did a wonderful job explaining the formations and how the cave came...More

Our guide Dakota was excellent. We took the Adventure tour and enjoyed the beautiful formations. It took about an hour and a half and was not very strenuous. Nice and comfortable in the caves...natural air conditioning! A good value

I can say this place is definitely amazing we spend about 2 hours and our guys was very informative. We definitely will come back to do another tour, just keep in mind is very tight space and it get dark and muggy at times.

What can I say, this is a cavern. Mostly sandstone color, some color some areas. lots of neat stalagmites and stalactites. Interesting finds of prehistoric bones. This cave was found while building the IH 35.

Shouldn't be a problem. They have a special tour for cavers but the normal tour is down corridors of stone larger than most elevators and then into large rooms. At one point you get to experience total darkness. Don't know... More

I'd like to know why my review was altered. I used the words "stalagmites and stalactites" but find "statutes and statutes" in the review. This alteration makes me appear to be an idiot. I would rather remove the review than to publish a review that makes me appear entirely stupid.

Could it be possible that the auto correct did the alteration and you didn't notice before posting? I have never had any of my reviews altered.
Is the tour appropriate for children aged 4 & 5?
