Recreation activities on the Coronado National Forest are nearly as diverse as the people who come to visit. The most popular ones are hiking, camping, birding, horseback riding, picnicking, sightseeing, and visiting historic areas. Fishing and boating are available but limited in this arid land, while opportunities for the fast-growing sport of mountain biking are growing. Winter sports are possible in the higher elevations; Mt. Lemmon Ski Valley in the Santa Catalina Mountains is the most southern ski area in the United States.
