Signal Mountain Wilderness
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.
