Guts 'n Giddyup Route (missing second half because text limits) - Trevor Roberts
The Guts 'n Giddyup Route is a self-guiding tour available to visitors with limited spelunking or diving experience and in good physical condition. This 4.75-mile tour follows the original explorers route, entering the sand gullet from the base of the Lower Visitor Center. This route descends over 750 feet into the pit, following slippery and narrow flesh tunnels through a large dorsal organ called the Trunk.
