3693 S. Old Spanish Trail, Tucson, Arizona
The giant saguaro cactus, with its huge upright arms extending from a sturdy trunk, may after some 200 years reach a height of 50 feet. Literally thousands of these giant saguaro cacti fill the Sonoran Desert here in the eastern section of the national park’s two units.
The plants and creatures of the desert can be studied closely on an 8-mile drive that loops through the saguaro forest and also on a 1-mile nature trail near a sheltered picnic area. Over 50 miles of hiking and horseback-riding trails traverse a 58,000-acre wilderness and ascend to the summits of the fir-forested Rincon Mountains at an altitude of 8,700 feet.
