Hidden Passage Adventure Tour February 28, 2011

Experience a thrilling and physically demanding 3 to 4 hour excursion into one of the world's premier caverns. Climb, crawl, rappel, explore - with only the light of your helmet to guide you. This is not for the weak of heart. Once outfitted with caving gear you'll be lowered by rope through a 160-foot well shaft. Travel approximately one mile, going down to 230 feet below surface level to the Fault Room which features one of the longest soda straw formations in North America - 14 feet in length. It's no wonder that these Caverns have become one of the most popular attractions in Texas.
