Inner Space Cavern Cavern & Cave

After being sealed for over 10,000 years, this cave was discovered in 1963 when a group of workers were digging to build a highway overpass. Daily tours are available and last just over an hour. The cave stays a comfortable 72 degrees Farenheit year-round, and features not only beautiful rock formations but also the remains of prehistoric mastodons, saber-tooth cats and other ice age animals. After your tour, enjoy the shaded picnic area with a playscape for children.

The cave was very interesting. We did this as the first stop on our 4 day tour of the Texas Cave Trail. Our guide (Breelee?) was knowledgeable, friendly, and funny. The cavern itself has an interesting history and lots of photo ops. Definitely recommend this one!

Although not one of the larger caves in the US, the tour isn’t bad for those who are interested in caves or have a couple hours to kill. It’s an easy walk and you cover about a mile in an ‘out-n-back’ or should I say and down and up tour. There are some interesting aspects to the cave, including how it was discovered and the plethora of dinosaur and other animal fossils that have been recovered. About 3/4 way through the cave several actual bones are displayed. Our guide was Mindy. She has been there for 4 years and was very knowledgeable about the cave. For those with more time or who are adventurous, there is a ‘flashlight’ tour held a few times during the day as well as a ‘wild caving’ tour. The latter is serious caving and only on the weekends and lasts approximately 4 hours.

Excellent tour with an informative guide. Narrowly avoided about 100 kids on a school trip! Actually their teachers did keep them pretty much under control. Note that the walkway through the cave is narrow, low, uneven and occasionally wet. Lots of handrails and floor mats to assist but if you have trouble walking you may want to reconsider. It’s about a mile in and out. Worst part is the exit about 200ft up a fairly steep incline. I was winded and had to stop but the guide was very understanding and waited for me. Thanks.

Very informative tour with a great touch of story telling along the way thru the cave. Our tour guide did a great job at taking care of his group and explaining things. Would highly recommend this tour for all especially families. There are many beautiful sites to see and if you like caves you will love this one.
