Inner Space Cavern
Discovered by a Texas Highway Department core drilling team in 1963, Inner Space Cavern still provides local and out-of-state visitors with a totally new form of exploration as they hike through and admire Nature's artwork that took millions of years to take form. From hour-long guided walking tours to more advanced all-day spelunking excursions, Inner Space isn't just another tourist stop; it's a chance to take in Texas's natural underground beauty free of the scorching summer heat.
