Natural Bridge Caverns was discovered in 1960 by four college students from St. Mary’s University. These young explorers first identified a cool draft coming from a crawl space, where they then climbed and crawled through the passage for two miles to reach the cavern. After notifying the landowners of their discovery, the cave’s first half mile was developed to allow guests to view this Texas treasure in 1964.

Natural Bridge Caverns is now listed in the National Register of Historic Places due to its richness in cultural history. During its development in the early 60’s, many ancient artifacts, approximately dating back to 10,000 years ago, were discovered. Stone tools, projectile points and knives were some of the items found, along with fossils from species that went extinct nearly 12,000 years ago.
