Ever Explore an Earthquake From Deep Inside The Earth?


Let us lead you into the Balcones Fault Line Cave: The only real earthquake cave open for viewing and an eye-opener to Mother Nature’s devastating raw forces. Our guides are trained to reveal stories of past geological eras of the Earth’s history on this awe-inspiring tour.  Fossilized prehistoric life encased in the many strata formations and huge boulders suspended mid-air are just part of the spectacular and rare sites the cave offers. Wonder Cave is uniquely different from other show caves and is both fun and educational for all ages. Established in 1903, we are the first commercial Show Cave to open for public viewing in Texas. Wonder World Park Cave and Attractions can be enjoyed year-round without being affected by weather conditions.
  • Are there other rooms in Wonder Cave not seen during the tour?
  • Yes. Exploration of these rooms would require individual flashlights, hardhats and rope.

  • Are there any organisms indigenous to Wonder World Cave?
  • Although an occasional spider, cricket, or roach may come in through the elevator shaft, the only indigenous creature is a black and white salamander.

  • Are there bats in Wonder Cave?
  • No. They have no way to get in. San Marcos does have a colony though; the Mexican Freetail bats live in the parking garage at Comanche and Vista streets on the Texas State University campus. They migrate to Mexico for the winter.

  • What is the difference between a cave and a cavern?
  • There is no difference. The cavern just refers to an especially large cave.

  • Has there been seismic activity in the Balcones Fault zone in recent times?
  • Although the Balcones Fault Zone is generally considered to be inactive, some scientists suggest the earthquakes that occurred just east of Austin in 1873 and 1902 were caused by movement along the eastern part of the fault system (Swanson, 1995). The closest earthquake to San Marcos occurred in Seguin in 1847. All of the above mentioned earthquakes had an estimated intensity of less than 5 on the Richter scale. The Seguin quake was estimated at 3.5.
