Descend beneath the Texas Hill Country and step into a world that has been forming for millions of years. Inner Space Cavern stretches beneath Georgetown along one of the most dramatic cave passages in the state, its ceilings draped in stalactites and its floors studded with glittering mineral formations. The cool underground air offers a welcome contrast to the Texas heat above. Inner Space Cavern rewards curious visitors with genuine geological wonder, from ancient flowstone curtains to fossils of mammoths and saber-toothed cats discovered when the cave was first uncovered in 1963.
