Tres Alamos Wilderness

General Location Maps Contacts Area Management Wilderness Laws Trip Planning Images


The United States Congress designated the Tres Alamos Wilderness (map) in 1990 and it now has a total of 8,300 acres. All of this wilderness is located in Arizona and is managed by the Bureau of Land Management. The Tres Alamos Wilderness is bordered by the Arrastra Mountain Wilderness to the north.


Columns of colorful stone are the most striking landscape features of Tres Alamos, a Wilderness in the southern Black Mountains. The landscape rises from about 2,300 feet and tops out at Sawyer Peak (4,293 feet), the highest point in the Black Mountains. The eastern portion of the area contains the Blacks' scenic ridgelines, canyons, and washes, while the western side consists of lower desert bajadas (slopes) and plains. On the bajadas and hills you'll find saguaro and paloverde. Joshua trees and creosote bushes dot the plains, and mesquite and acacia line the washes. The Gila monster lives here in seclusion, and prairie falcons and golden eagles rule the skies.

Although there are no established trails, the area is suitable for hiking and camping. Horsepackers sometimes journey through. Daytime temperatures during the summer months are over 100 degrees. Temperatures are more moderate between October 1 and April 30th.
