Wonder World Cave

Wonder World Cave & Adventure Park is fun for the whole family and has been a San Marcos must-visit for more than 100 years! 

Cave Tours
Journey deep underground into the Balcones Fault Line Cave, the only real earthquake-formed cave open for viewing, on a guided tour. You’ll learn all about past geological eras, see fossilized prehistoric life, and see what damage an earthquake can do! People have been exploring this cave since 1903 when visitors were charged 10 cents for a candle-lit tour. Don’t worry, there are electric lights down there now… 

Texas Wildlife Petting Zoo
The whole family will love hopping aboard the train and going to see some friendly locals at the petting zoo. You can feed and pet deer, pigs, goats, emus, are more. Feed is available for purchase at the Train Station before your journey.  

Anti-Gravity House
The Anti-Gravity House always mystifies and makes for a great photo opportunity. You’ll notice the rules of nature don’t really apply in the topsy-turvy world of the Anti-Gravity House and things that go up do not always come back down and water even runs uphill. 

What To Know Before You Go
Tours leave every 20-30 minutes. The train ride takes is about a 30-minute adventure. 

It’s advised visitors wear comfortable walking shoes, as you will be exploring a cave with rocky terrain or potentially wet ground. The train is wheelchair accessible, but the cave and Anti-Gravity House are not. Strollers are not allowed for tours.
