A one-of-a-kind Theme Park, known as the 1st show cave in Texas. Visitors have enjoyed touring the Balcones Fault Line Cave for over 105 years, and now, the park has many other attractions for family fun and entertainment.

Guided tours show the the nation?s only true example of an EARTHQUAKE-FORMED CAVE. Go deep underground and see up close the devastation of a major quake. Exit by the ?Stratavator? and ride high into the sky to the Tejas Observation Tower. Be amazed by the Topsy-Turvy World of the anti-gravity house where everything is backwards, even water flows up hill!

There is a train that tours the property and before crossing the street through a tunnel goes under a waterfall.
