The First Show Cave in Texas


​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.

"My family enjoyed the cave tour (45 min), the ride up into the tower, a trip through the anti-gravity house, and a train ride through the animal park. Staff member all around were super! If you take children, the gift shop is like a gold mine!"

"Have been here several times, most recently with my grandson. He loved the cave excursion and then walking through the mirror maze."

"No, seriously, Wonder World is the most awesome 50/50 cool/cheesy roadside attraction that used to make family cross country travel so much fun. Wonder World is what the American Roadside used to be."
