January Coupon Code — $100 Natural Bridge Caverns Last Call

In March 1960, four students from St. Mary's university in SAN Antonio, Orion Knox Jr. , Preston Knodell, Al Brandt and Joe Cantu, received permission to explore the area, now known as Natural Bridge Caverns. The students were convinced of the existence of large subterranean passageways under the stunning 60-foot limestone bridge. On their fourth expedition, Orion gets a cool draught from a gravel filled crawl. Such airflow usually indicates the presence of other rooms or passageways. The explorers carefully climbed and crawled along two miles of cavernous passageways. After making this amazing discovery, they went back to the ground and told the landlord. The discoverers immediately knew what Natural Bridge Caverns had made a surprising discovery, and the landowner decided to develop the first 1/2 mile (the most spectacular part of the cave) for guests around the world to enjoy. Now the first 1/2 mile is the journey of discovery.
