Welcome to Wonder World Park, 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. Discover the nation’s only true example of an earthquake formed cave on a guided tour. 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 Observatory Tower. Be amazed by the Topsy-Turvy World of the Anti-Gravity House where everything is backwards, even water flows uphill! Board the train and splash through the waterfalls of Mystery Mountain on your way to the Texas Wildlife Petting Park.
