Signal Mountain Wilderness

Overview

The 13,350-acre Signal Mountain Wilderness is in southwest Maricopa County, 18 miles northwest of Gila Bend and 35 miles southwest of Phoenix. This wilderness is adjacent to the 64,000-acre Woolsey Peak Wilderness just to the southeast, separated by a four-wheel-drive road.

This wilderness offers a variety of scenery, including sharp volcanic peaks, steep-walled canyons, arroyos, craggy ridges and outwash plains. Signal Mountain, at the area's center, rises 1,200 feet above the desert floor to an elevation of 2,182 feet. Paloverde-saguaro and creosote bush bursage plant communities are found throughout bajada and upland areas, while washes are lined with mesquite, ironwood, acacia and paloverde..

This wilderness provides several primitive recreation opportunities, such as rock climbing in the canyons and valleys around Signal Mountain, day and overnight hiking, rock collecting, and deer and quail hunting. Fortunate visitors may observe desert bighorn sheep, desert tortoise, mule deer and various raptors.
