Natural Bridge Caverns is the largest known commercial caverns in the U.S. state of Texas. Discovered in 1960, the caverns offer a variety of tours that take visitors 180 feet below ground to see massive chambers and intricate formations.
Beyond the walking tours, the park offers adventure tours where guests can crawl and climb through undeveloped sections. Above ground, visitors can test their agility on the Twisted Trails ropes course and zip rails.
The caverns are a living geological system, with water still shaping the formations. Highlights include the Castle of the White Giants and the Hall of the Mountain King, showcasing the beauty and power of nature.
