The Huachuca Mountain range is part of the Sierra Vista Ranger District of the Coronado National Forest. The Huachuca Mountains are located in Cochise County, Arizona approximately 70 miles (110 km) south-southeast of Tucson and southwest of the city of Sierra Vista, Arizona. Included in this area is the highest peak in the Huachucas, Miller Peak, and the region of the Huachucas known as Canelo Hills in eastern Santa Cruz County. The mountains range in elevation from 3,934 feet (1,199 m) at the base to 9,466 feet (2,885 m) at the top of Miller Peak. The second highest peak in this range is Carr Peak, elevation 9,200 feet (2,804 m). The Huachuca Mountain area is owned principally by the USDA Forest Service (Coronado National Forest) (41%), the U.S. Army (Fort Huachuca) (20%), and private land (32%). Sierra Vista is the main population center (41,908 inhabitants as of 2005 Census).
Vegetation in the Huachucas varies from Chihuahua Whitethorn scrub and semi-desert mixed grass/mixed scrub, at the lower elevations, to Encinal mixed oak, and transitions to Ponderosa Pine and Apache Pine at the highest elevations.

Hiking the Mountains
The Huachucas present many hiking possibilities and scenic drives. Some entail narrow dirt roads with switchbacks and pull-outs. High summits, sheer cliffs, and deep canyons distinguish this rugged area of 20,190 acres (81.71 km2). Trails climb from all sides of the range to the Miller Peak Wilderness. Along the trails there are opportunities to see a number of rare butterflies of Arizona (see List of butterflies and moths of Arizona), as well as plants that are more commonly found in the Sierra Madre Occidental. Trails begin on the east side of Ash Canyon, Miller Canyon, Carr Canyon, and Ramsey Canyon Roads, from the south at Montezuma Pass in the Coronado National Memorial, and from the west via Oversite trail, Ida, Bear, and Sunnyside Canyons. The 11.5-mile (18.5 km) Crest Trail between Montezuma Pass and Fort Huachuca ties all of the trails together. There are some 50 trails altogether.  These mountain trails are also a main migration route for illegal immigrants from Mexico The mountains include the type locality for a number of plant species collected by the Lemmons and named by Asa Gray.
This area is appreciated for its birdwatching opportunities including some Arizona specialties such as hummingbirds, trogons, and tyrant flycatchers, including some rare birds such as the Blue-throated, White-eared, and Berylline Hummingbirds; also Buff-breasted Flycatchers; and Black-throated Gray, Red-faced, and Grace's Warblers; also Red Crossbills and numerous other bird species.
