Saguaro National Park is home to the saguaro cactus and many other plants and animals common to the Sonoran Desert. The ocotillo, creosote bush, mesquite, teddy bear cholla, prickly pear cactus, and barrel cactus all cover the slopes of this 91,445 acre park in southern Arizona, on the outskirts of Tucson.
The park consists of two districts on parcels on the east and west sides of Tucson. The Rincon District lies on the slopes of Rincon mountain on the east side of Tucson, while the Tuscon Mountain District occupies the mountain on the west side. The main roads in the latter were photographed in the spring of 2004.
The Tucson Mountain District occupies the northwest tip of the Tucson Mountains which separate the Santa Cruz Valley (where Tucson lies) from the Avra Valley. The highest point in the park is Watson Peak at 4,687 feet, which is some 2,500 feet higher than the surrounding valleys.
Saguaro National Park, being a more obscure park, was visited by 642,457 people in 2002. It became a national park in 1994, after being a national monument since 1933.
