Signal Mountain Wilderness

General Location Maps Contacts Area Management Wilderness Laws Trip Planning


The United States Congress designated the Signal Mountain Wilderness (map) in 1990 and it now has a total of 13,350 acres. All of this wilderness is located in Arizona and is managed by the Bureau of Land Management.


Congress added the Signal Mountain and Woolsey Peak portions of the Gila Bend Mountains to the National Wilderness Preservation System in 1990. 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.

Planning to Visit the Signal Mountain Wilderness?

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.
