A narrow squeeze through boulders leads down to the deepest point on the tour, The Dining Room. A pit hidden in the corner is the jumping-off point for the wild cave tour. A steep climb along sand pathways leads to the base of the Devil s Staircase, the bottom of 50 foot deep pit used for rappelling classes. The chamber ceilings are very low in places, and the muted lightning makes tour stragglers feel like they re exploring a wild cave. From the base of the Grand Canyon, it s a steep climb up the hill.
Railings help the weary, and colored lights accentuate the ceiling.
You can t tell by looking that the gutter is on a downslope, but a level would prove it. Beyond, the Christmas Tree Grotto beckons. A labyrinth passage, dubbed Vallanoren, is lit by colorful sound-activated lights. If you don t make noise, the lights go out. At the top of the passage is the unique Pillar of Hercules formation.
