In 1924, National Geographic expedition members wrote about the wonders of Lower Cave. Visitors today can see the evidence left behind from these and other explorers. Highlights of this tour include The Rookery, with countless nests of cave pearls, the Colonel Boles Formation, and an incredible diversity of cave formations that compete for your attention almost everywhere you look. Ladders at the entrance to Lower Cave sometimes cause participants to back out. If you have a fear of heights or difficulties with ladders, you may wish to consider visiting
Left Hand Tunnel instead.
