Old Caves Crater: An Ancient Pueblo Hiding on a Volcano Near Flagstaff

There is an archaeological site on top of a volcano just 15 minutes from downtown Flagstaff. Old Caves Crater is an extinct volcanic cinder cone with a collection of small caves that were once built into a Sinagua pueblo dating back to the 1300s. Archaeologists believe the settlement had roughly 70 to 80 rooms.

On the way up you get views of the San Francisco Peaks, Mount Elden and the surrounding volcanic landscape. It is a good workout with a little history and adventure thrown in.
