Saddle Peak Hills Wilderness, Protected wilderness area in San Bernardino County, California.

Saddle Peak Hills Wilderness is a protected area in San Bernardino County spanning thousands of acres with elevation changes from low desert valleys to rocky hilltops. The terrain shifts between open sandy flats and brush-covered slopes that create varied habitats across the landscape.

A 1980 Bureau of Land Management report judged the area unsuitable for wilderness designation because copper, lead, silver and talc deposits were considered commercially viable. It was nevertheless designated wilderness on 21 October 1994 under the California Desert Protection Act, making it the smallest wilderness area created by that law.

The wilderness area functions under the Leave No Trace principles, promoting environmental stewardship and responsible outdoor recreation practices for all visitors.

Visitors must travel on foot without motorized vehicles or machinery, as these are not permitted in the protected area. Sturdy footwear and plenty of water are necessary for moving through the hilly and sandy terrain.

The Mojave fringe-toed lizard, found in a sandy patch of about 3 square miles (1,920 acres), has fringed toes that let it run and burrow in loose sand. The 1980 BLM report had judged the area unfit for wilderness because of copper, lead, silver and talc deposits worked here historically.
