It gets the name from a sound made when water drips from the ceiling into long tubes worn in the formation below, that combined with the shape of the cave, produce a sound at the entrance. Visitors can get into the cave via an over 100 foot spiral staircase or by rappelling. An average urinal at an above average spot."
