Why Visit Wilderness?

Although you can certainly appreciate wilderness from afar—online, on television, or in books—first-hand experiences in nature such as campng or hunting enable you to enjoy the recreational, ecological, spiritual, and health benefits that wilderness areas provide. Wilderness areas provide “outstanding opportunities for solitude or a primitive and unconfined type of recreation,” opportunities to see wildlife, a chance to renew and refresh, and the health benefits of exercising outside. You can even bring your well-behaved dog to many wilderness areas.

Learn more about the diverse ways in which we benefit from wilderness and threats wilderness areas face today.

A thin four-wheel-drive road is all that separates Signal Mountain Wilderness from Woolsey Peak Wilderness to the south. Signal Mountain itself, rising just north of the center of the area, reaches a summit at 2,182 feet (1,200 feet above the surrounding desert floor). Here you'll find sharp volcanic peaks, steep-walled canyons, ragged ridgelines, arroyos (slim, usually dry riverways), and plains spreading out from the washes. Paloverde, saguaro, and creosote bushes are scattered throughout the bajadas and upland regions. Washes are lined with mesquite, ironwood, acacia, and more paloverde. Wildlife watchers may see desert bighorn sheep, desert tortoises, and several species of raptors. A large number of quail live here, and quail and mule deer hunters are frequent visitors. Rock climbers are beginning to flock to the valleys and canyons around Signal Mountain, where bold cracked faces offer a multitude of routes of varying difficulty.

Leave No Trace

Leave the area as you would like to find it. Pack out all trash; do not bury it as animals will dig it up after you leave. Dogs disturb wildlife and other visitors; if you bring a dog, keep it under control at all times. If you need a fire, keep it small and away from rock outcrops. If you build a fire ring, please dismantle it when you are through and bury the ashes before leaving the area. Cigarette butts, pull tabs, orange peels, etc. are all litter. PACK IT IN-PACK IT OUT.

Location

The 13,350-acre Signal Mountain Wilderness is in southwest Maricopa County, 18 miles northwest of Gila Bend, AZ and 35 miles southwest of Phoenix, AZ. This wilderness is adjacent to the 64,000-acre Woolsey Peak Wilderness, just to the southeast separated by a four-wheel drive road. The most frequently used access to Signal Mountain Wilderness and Woolsey Peak Wilderness is via Old U.S. 80, a paved highway, the Agua Caliente Road, an improved dirt road, and jeep trails. Travel to Signal Mountain Wilderness requires a high-clearance, four-wheel drive vehicle. The Signal Mountain Wilderness is bounded on the north by point-to-point, cross-country lines. The eastern and southern boundaries are primitive, two-track vehicle routes, and the western boundary is comprised of a grazing allotment boundary fence and ephemeral desert wash. For specifice access contact the Lower Sonoran Field Office.

Maps

Digital and paper maps are critical tools for wilderness visitors. Online maps can help you plan and prepare for your visit ahead of time. You can also carry digital maps with you on your GPS unit or other handheld GPS device. Having a paper map with you in the backcountry, as well as solid orienteering skills, however, ensures that you can still route-find in the event that your electronic device fails.
