About this place
The Big Horn Mountains Wilderness Area covers 21,000 acres, 60 miles west of Phoenix in western Maricopa County.
Big Horn Peak is steep. It rises 1,800 feet. That peak and the escarpments on the desert plain around it give the wilderness its scenery, and you can see it from Interstate 10.
The Hummingbird Springs Wilderness lies northeast of here. A jeep trail runs between them.
Nine miles of jumbled Big Horn Mountains ridgeline cross the wilderness.
Around the mountainous core there are smaller hills, fissures, chimneys, narrow canyons, and desert plains running out from them.
There is walking, backpacking, rock climbing, photography and nature study, and the rugged ridges will test even expert climbers. The side canyons and plains are easier going.
Desert species live here: the desert bighorn sheep, the Gila monster, the kit fox and the desert tortoise.
Golden eagles, prairie falcons, barn owls and great horned owls all have nests in the cliffs.
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.
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.

Every distance on this page is the driving distance. A short distance can still take a long time. The road may be closed for the season, covered in snow, or washed out. Many of these roads are dirt. Plan your route before you leave home. Out here there is often no phone signal to look it up on the way.
Nearest town and supplies

- Salome, AZ Directions
Salome 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.

Add road notes for this site
The thing we cannot get from any government record is what the drive in is actually like. If you have done it, this is the most useful thing you can leave behind. We read everything before it appears, and we print a first name with it if you give one.
Thank you. A person will read it before it goes on the page.
