Woolsey Peak Wilderness

Congress added the Woolsey Peak portion of the Gila Bend Mountains to the National Wilderness Preservation System in 1990, citing the rugged topography, colorful scenic vistas, rich variety of wildlife and vegetation, and outstanding opportunities for solitude and unconfined recreation in both areas. This 64,000-acre wilderness area is a perfect example of pristine Sonoran Desert.

Rising 2,500 feet to an elevation of 3,270 feet, Woolsey Peak is a prominent and scenic landmark of southwestern Arizona. Large washes, lined by thick stands of paloverde and ironwood, wind through sparsely vegetated, rock-strewn hills and desert plains below the major peaks. 

Wildlife includes mule deer, bighorn sheep, javelina, and numerous varieties of birds, lizards, and snakes. This wilderness area offers outstanding opportunities for cross-country foot and horseback travel, route finding, and wildlife viewing. There are no marked trails, campsites, or other developed recreational amenities — this area is recommended only for experienced and prepared wilderness visitors!
