Overview

This 21,000-acre wilderness lies 60 miles west of Phoenix in western Maricopa County. The precipitous 1,800-foot-high Big Horn Peak and neighboring desert plain escarpments give the wilderness exceptional scenic value, especially noticeable along Interstate Highway 10 south of the area. The Hummingbird Spring Wilderness, northeast of this area, is separated from the Big Horn Wilderness by a jeep trail.

Nine miles of the jumbled Big Horn Mountains ridgeline cross the wilderness. The central mountainous core is surrounded by smaller hills, fissures, chimneys, narrow canyons, and desert plains. This wilderness offers many recreation opportunities such as hiking, backpacking, rock climbing, photography and nature study. Rugged ridges challenge expert climbers, while side canyons and plains offer easier hiking.

This wilderness fosters habitat for many desert species, such as the desert bighorn sheep, Gila monster, kit fox and desert tortoise. Golden eagles, prairie falcons, barn owls and great horned owls nest in the cliffs.
