History of Natural Bridge Caverns

The story of the Natural Bridge Caverns begins more than a half-century ago. In 1960, four college students from St. Mary's University in San Antonio obtained permission to explore the area, which was believed to hold caverns beneath the surface. Indeed, their intuition proved correct, as they discovered large underground passages filled with an array of geological formations.


The discovery was monumental because it unveiled a previously hidden part of Texas's natural heritage. The landowners, the Wuest family, developed the find into a show cave, which opened to the public in July 1964. Since then, it has been continuously developed and expanded with careful preservation to ensure its natural beauty remains intact while being accessible to visitors.

Since its opening, the Natural Bridge Caverns have fascinated millions of visitors. It's a testament to the sheer power of natural processes, as the caverns' formations have been slowly sculpted by water percolating through the earth over countless millennia. The caverns' development has also provided opportunities for geological research and education, contributing to our understanding of the region's natural history.
