Chiricahua National Monument is a beautiful and unique off the beaten path pocket of wilderness in the southeast corner of Arizona. The area is known as a sky island - an isolated mountain range that rises above the vast surrounding sea of desert. As the elevation increases, the cacti and mesquite give way to sycamore, juniper and oak trees and eventually cypress, pines and fir. But what really stands out about Chiricahua National Monument are the amazing rock pinnacles found towering throughout the park.
