Grand Canyon Caverns, Peach Springs

4.0
#57 of 184 in Nature in Arizona
The Grand Canyon Caverns (Havasupai: Ŧathiil Ñwaʼa or Ŧathiil Ñhaʼa, 35°31′44″N 113°13′54″W), located just a few miles east of Peach Springs, Arizona, lie 210 feet (64 m) below ground level. They are among the largest dry caverns in the United States. Dry caverns compose only 3% of caverns in the world. Because of the lack of water, stalagmites and stalactites are rare in the caverns.


During the Mississippian Period, 345 million years ago, the southwestern United States was covered by ocean. Skeletons of sea life settling to the depths, created a mud with a high percentage of calcium. This eventually hardened into the limestone bedrock seen in the caverns today. Over millions of years, the bedrock was pushed up to over 5,000 feet (1,500 m) above sea level.


Approximately 35 million years ago, rainfall flowed into the rock, and eroded passages that lead to the Colorado River and what is now the Grand Canyon. Millions of years later, the evaporating water left calcium deposits on the walls and floors, creating the formations that can be viewed today.

  • Good food. The cavern tour is interesting. I would say the walking is moderate due to the terrain and some areas are steep for non-fit folks. Temps inside the cavern is around 62 degrees so wear according based on your body. Staff is knowledgeable and fun.
  • Group of 8... had a fabulous time! The caves were much bigger than expected! Food looked amazing in restaurant. We have a slice of banana pie and cheesecake. Both absolutely delicious! Would highly recommend going!
