READY FOR ADVENTURE? Check out the Inner Space Cavern

Inner Space cavern was discovered by a Texas Highway Department core drilling team in the Spring of 1963. Six inch core samples were taken to determine if the ground was stable enough to support a large highway overpass. As they were drilling one of the test holes, the bit suddenly dropped 26ft. and the highway crew knew there was something down there besides rock.

Inner Space was opened to the public in the summer of 1966, and since that time hundreds of thousands of visitors have seen this beautiful cave. To learn more or plan a trip, click here.
