Tucson Mountain Park is a 20,000 acre Sonoran Desert natural preserve located a few miles west of Tucson. Tucson Mountain Park contains one of the most magnificent saguaro forests in the world. Hiking, horseback riding, bicycling, picnicking, and camping are some of the recreational opportunities within this desert park.
