I took my two grandkids here since they were studying rocks in school. They thought it was awesome. You do have some hard walking to do. Not all flat and level, some minor ramps to climb. The tour is worth the money.

My wife and I decided to go to the ISC even though we have been to many other caves and caverns in the past. The tour guide, Rick, was excellent with the kids in the group, he was very knowledgeable and informative. We did find that the tour was interesting but these caverns did not have as many formations as... More

This attraction is amazing inside...once you get over how incredibly expensive it is! Very cost prohibitive for families.

My kids and I enjoyed this place and it was a fun road side stop off for the afternoon. I would recommend this if you have time.

Visiting friend from Wisconsin, we thought it would be a good way to pass the time. The actual cave was very easy to manage and can be enjoyed by children as well as older active adults. The Cave temps is a little warmer than other caves in Texas, but still comfortable. The guide was informed but the presentation was a... More

We had a very small tour of 7 people in the afternoon on a Thursday. Our group of 5 was 3 adults and 2 kids and was $90. They don't offer a military discount. I avoided morning fieldtrips by checking their website before we visited. We were warned it would be hot and humid inside but I thought it was... More

Great guided tour, very interesting and pretty. Our guide Rick managed to keep the level of information interesting for all ages 7- 70. Nice gift shop with lots of rock items. Definitely worth a stop.

First off this cave has so much more to offer than what you can see and is a great way to teach your kids history and science. There are activities more than exploring the cave here and the time you spend are worth it.

We filled our New Year's Eve afternoon by taking the visitors here, including a 10-year-old. The place was overly crowded with endless busses of people, and our tour had to constantly move to the side for the other tours and their dawdlers to move through. Also because there were so many tours, ours was abbreviated. That said, it was a... More

We had two families with children ranging from 2-9. It was probably not all that fun for the two youngest, but our 7,8 and 9 year old kids had a great time. It says it takes about 1 and 15 minutes, but we were done in 50 minutes. Our guide, Jake, was hilarious and informative. I would highly recommend asking... More
