Earthquake-formed Wonder World Cave in San Marcos
Photographer: Kevin Stillman

Wonder World

The only earthquake-formed cave in the nation open to the public offers a nature-tourism experience focused on Texas' geology and history. Unlike water-formed caves, this cave is not harmed by touch or light and visitors are encouraged to take photos and touch the cave. Highlight of tour is visit to dark room where minerals imbedded in the cave glow in various colors reflecting the properties of the rocks. The Tejas Observation Tower gives an aerial view of the Balcones fault line and the city of San Marcos, located on the edge of the Texas Hill Country. Also wildlife petting area, train ride, anti-gravity house and gift shop. Open daily. Closed Christmas Eve and Christmas Day. See website for hours. Admission charge. Exit 202 off I-35 to Wonder World Drive. 512/392-3760. www.wonderworldpark.com.
