OverviewWasson Peak is the high point of the west unit of Saguaro National Park. Located in the Tucson Mountain Range, Wasson Peak provides an excellent view of Tucson and several surrounding mountains, including Mts. Lemmon and Wrightson and Baboquivari, Kitt and Picacho Peaks. Because of its accessibility and outstanding views, Wasson Peak is a popular destination. It’s a great way to experience Saguaro National Park and the Sonoran Desert. There are several trails leading to the summit.
Saguaro National Park
As development in the Tucson area continues to spread, Saguaro National Park is an increasingly important refuge for many Sonoran Desert species. Originally established as a national monument to protect examples of the Sonoran Desert and several outstanding stands of saguaro cactus, it became a park in 1994.
The park has two units. The West Unit, where Wasson Peak is located, consists primarily of Sonoran Desert vegetation and contains part of the Tucson Mountain Range. The larger East Unit, which abuts the east side of Tucson, contains the higher Rincon Mountains and encompasses a wide variety of ecosystems, from Sonoran Desert to Douglas fir forest near the ridge tops.
Wasson Peak is located in the Arizona Upland subdivision of the Sonoran Desert, which is a relatively wet part of the Sonoran Desert. The Tucson Mountains receive fourteen inches of rain per year, mostly during the winter and summer.
This area contains many species of cacti. Most notably, the saguaro (pronounced “suh-wah-roe”) cactus dominates much of the area. To many, this tall cactus, with its long, upturned "arms," epitomizes the desert southwest. Saguaro cactus has a broad geographic range and is common in hilly areas of the Sonoran Desert. In addition, there are several other cactus species, including the south-leaning fishhook barrel, and several species of cholla (including teddy bear, pencil, staghorn, buckhorn, and hanging fruit), hedgehog, pincushion, and prickly pear cacti.
Besides cacti, there are several other distinctive Sonoran Desert plant and animal species. Foothill paloverde trees, mesquite, ocotillo, jojoba, several agave species, including sotol and shindagger, and other desert plants are quite common. There are also several animal species, including the pig-like javelina, bighorn sheep, coyotes, snakes (including several venomous species), lizards, cactus wrens, canyon wrens, Gila woodpeckers, phainopeplas, Harris’ hawks and northern mockingbirds.
The Arizona-Sonora Desert Museum, which is adjacent to the park on the way to the visitor center (see "Getting There" below), is a great place to learn about and appreciate the Sonoran Desert.
