A Glimpse into History
The caverns’ story begins millions of years ago when limestone formed under ancient seas. Human history entered the picture in 1927 when Walter Peck stumbled upon the cave, initially hoping to mine gold. Instead, he turned it into a tourist attraction, charging 25 cents for daring visitors to descend via ropes. During the Cold War, the caverns were designated as a fallout shelter, stocked with supplies that are still visible on some tours.

A Sacred Site
The Hualapai, whose ancestral lands encompass the area, consider the caverns a sacred site, tying their cultural heritage to the depths of the caverns. Revered by the Hualapai people as a sacred burial site, the caverns’ natural entrance remains sealed out of respect, with visitors descending 21 stories via elevator to explore its subterranean chambers, including the ‘Chapel of the Ages’ and ‘Halls of Gold.’ Nearby Peach Springs, a historic Hualapai community, remains a hub along Route 66, blending Native history with the road’s nostalgic charm.
