About Inner Space Cavern

Discovered by accident during highway drilling, this 10,000-year-old Texas cavern offers everything from a paved guided stroll to a crawl-and-climb wild cave trek.

Hidden underground for over 10,000 years until a highway crew drilled into it, Inner Space Cavern reveals vast chambers, dramatic formations, and traces of prehistoric animal life.

What you'll see and do - Take the Adventure Tour, a guided walk on paved, lit trails through the cave's largest and most decorated areas. - Go deeper on the Hidden Passages Tour, a rugged flashlight exploration (not advised for those with claustrophobia or physical limitations; ages 7 and up). - Tackle the Wild Cave Tour, a physically demanding journey through undeveloped sections for ages 13 and up. - Add a thrill above ground with the Saber Tooth Zip Ride.
