The Natural Bridge Caverns were discovered on March 27, 1960 by four students of Saint Mary's University in San Antonio. It was named for the Rock Bridge that marks the entrance. Of early cretaceous age, the caverns are still forming site of artifacts from 5,000 B.C. and human remains at least 8,000 years old. Old Indian campsites were also found here.

We took the Discovery tour. The walking tour was 75 minutes, three quarters of a mile and took us 180 feet below the ground where we saw awe inspiring, ancient formations centuries in the making and still growing today, such as stalagmites, stalactites, and flowstones. Cavern temperature is 70 degrees with a relative humidity of 99%.
