The Coronado National Forest is a United States National Forest that includes an area of about 1.78 million acres spread throughout mountain ranges in southeastern Arizona and southwestern New Mexico.
It is located in parts of Cochise, Graham, Santa Cruz, Pima, and Pinal Counties in Arizona, and Hidalgo County in New Mexico.
The national forest is divided into five ranger districts, which are not contiguous; each consists of multiple sky island mountain ranges.
The Santa Catalina Ranger District near the city of Tucson comprises the Santa Catalina and Rincon Mountains. Included in this area are the highest peak of the Santa Catalinas, Mount Lemmon, the rugged Pusch Ridge Wilderness Area, and the popular Sabino Canyon. Much of this district was part of Santa Catalina National Forest before its inclusion in Coronado.
The Safford Ranger District comprises the mountain ranges surrounding the city of Safford, Arizona. These five ranges are the Pinaleño, Galiuro, Santa Teresa, Winchester, and Greasewood Mountains. Included in this area is the highest peak of the Pinaleños, Mount Graham.
