Discover more about Grand Canyon Caverns

Venture into the depths of the Grand Canyon Caverns, a natural wonder formed over millions of years. These caverns, situated a few miles east of Peach Springs, Arizona, offer a unique opportunity to explore one of the largest dry cave systems in the United States. The caverns' story began around 345 million years ago when the southwestern U.S. was submerged under an ancient sea. Over time, the skeletons and shells of sea creatures formed a lime-rich mud that eventually hardened into the limestone bedrock of the caverns. As the land rose and climate shifted, rainwater seeped through cracks, gradually carving out cavities and passageways. The lack of constant water flow resulted in a 'dry' cave system, where stalactites and stalagmites are rare. In more recent history, a woodcutter named Walter Peck stumbled upon the caverns in 1927 while on his way to a poker game. Initially believing he had struck gold, Peck soon realized his mistake but decided to capitalize on the discovery by offering tours. Early visitors were lowered into the caverns by rope, a practice known as 'dope on a rope'. During the Cold War era, the U.S. government designated the caverns as a fallout shelter, stocking them with supplies for 2,000 people. Some of these supplies remain on display today. Today, visitors can explore the caverns through a variety of guided tours. Descend 200 feet via elevator and wander through paved walkways, marveling at formations like the Chapel of the Ages, the Halls of Gold, and the Devil's Den. For the adventurous, off-trail 'Explorer Tours' offer a chance to crawl and climb through less-traveled sections of the caverns. The caverns maintain a constant temperature of 56 degrees Fahrenheit (13 degrees Celsius) year-round.
