About this place
Congress added the Woolsey Peak part of the Gila Bend Mountains to the National Wilderness Preservation System in 1990.
It cited the rugged ground, the colorful views, the range of wildlife and plants, and the solitude.
The wilderness covers 64,000 acres. It is a perfect example of pristine Sonoran Desert.
Woolsey Peak rises 2,500 feet to an elevation of 3,270 feet, and it is a landmark of southwestern Arizona.
Large washes wind through sparsely vegetated, rock-strewn hills and desert plains below the main peaks, lined by thick stands of paloverde and ironwood.
Mule deer, bighorn sheep and javelina live here, along with a great many birds, lizards and snakes.
This is country for cross-country travel on foot or on horseback, for route finding, and for watching wildlife.
Nothing is laid on. There are no marked trails and no campsites. Come only if you are experienced and prepared.
Wilderness means hard walking and real solitude.
Follow the rules for the area, and leave no trace, so it stays that way.
Motors and machines are generally banned on any federal land designated as wilderness. That covers motor vehicles and off-highway vehicles, motorboats, bicycles, hang gliders, wagons, carts and portage wheels. Landing an aircraft or a helicopter counts too.
Ask the agency if you need more on the rules. The detail matters in a wilderness, and getting it wrong carries a penalty.
You need a high clearance vehicle, and four-wheel drive is better. The exception is parts of the Enterprise Road south of Gillespie Dam.
Some of the land around the wilderness, and inside it, is not federal. Do not cross it or use it without the owner’s permission.

Gila Bend is big enough that you’d normally expect fuel and somewhere to buy food. Nobody from here has been to check, so don’t count on it if you’re running low.
