Seek out adventure with a spelunking experience at Natural Bridge Caverns. A new tour offers a physically demanding, but thrilling excursion into one of the world's premier caves.

You'll be outfitted with caving gear and lowered by rope through a 160-foot well shaft (or you can use the walk-in tunnel!) You climb, crawl, and rappel through undeveloped rooms and passages through the mile long tour that goes as deep as 230 feet below the surface, where you can see the longest soda straw formation in North America (14 feet!)

Special reservations are required and there are some stature limitations. Call 210/651-6101 for more information.
