The Santa Rosa Mountains are a short mountain range in the Peninsular Ranges system, located east of the Los Angeles Basin and northeast of the San Diego metropolitan area of southern California, in the southwestern United States.
The Santa Rosa Mountains extend for approximately 30 miles (48 km) along the western side of the Coachella Valley within Riverside, San Diego, and Imperial Counties in Southern California. The range connects to the San Jacinto Mountains on its northern end, where the Pines to Palms Highway—California State Route 74, crosses them.
The highest peak in the range is Toro Peak (elevation 8,716 feet (2,657 m)), located approximately 22 miles (35 km) south of Palm Springs, just south of Route 74, and on the northeast side of Anza-Borrego's Upper Coyote Canyon. The Santa Rosa Mountains are also a Great Basin Divide landform for the Salton Sink Watershed on the east.
