Natural Bridge Caverns has two world class caves for you to explore. On the Hidden Passages Tour, light and darkness combine to enhance your exploration of huge underground chambers decorated with some of our most rare and delicate formations. The Hidden Passages are highly decorated with unusually long soda straw stalactites, waves of cave ribbon and a profusion of intriguing welt and turnip shields. Another unique experience only offered on this tour occurs when all the lights are turned off and you experience total darkness. You havent seen all of Natural Bridge Caverns until you have experienced the Hidden Passages. Tours leave every 40 minutes and take approximately 70 minutes. Fee: 12 and older $19.99; ages 3-11 $17.99. Open daily except Thanksgiving; Christmas and New Years Day. Fee
