Consisting mostly of the Santa Catalina and Rincon mountains north and east of Tucson, this unit is a well-known producer of mature Coues deer. A few good-sized mule deer live here, mainly at lower elevations in the foothills of larger mountain ranges.

Unit 33 is one of Arizona's best units for hunters looking for big Coues and mule deer. Being in shape and willing to work hard will improve your chances of success.

The Santa Catalina Mountains are rugged and steep, reaching as high as 9,157 feet at Mount Lemmon. The Rincon and Little Rincon Mountains on the southeast side of the unit, which are also rugged and high, also hold deer populations. Part of the Rincons are designated as a wilderness area. Most mountain ground is public, mostly in the Coronado National Forest. Private land at low elevations restricts access to some areas. Low elevations consist of flat desert plains with washes and canyons.

Low elevations are Sonoran Desert and Chihuahuan Desert, which are both ecosystems featuring various species of shrubs, cactus and grass. Chaparral gives way to pines, firs and spruces at high elevations. Several burns have eliminated some dense vegetation, creating open areas and openings in dense cover.

The vast majority of this unit is public, divided among the Coronado National Forest, Saguaro National Park, two wilderness areas, large expanses of state land, a bit of BLM property and some private property, which is mostly at low elevations. Private property restricts access to some places.

Camping is allowed on Coronado National Forest lands as well as on most BLM and state property. Lodging is in Tucson, Benson, Oracle, San Manuel and Mammoth. Developed campgrounds include:
