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.
Enjoy a guided tour and discover 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! Board the train and splash through the waterfalls of MYSTERY MOUNTAIN on your way to the TEXAS WILDLIFE PETTING PARK.
Educational and fun for ALL ages, Wonder World Park Cave and Attractions is just minutes from I-35 in San Marcos between Austin and San Antonio. We are open year round. Gift shops, free picnic grounds, free parking and much more await your visit.
