The Mexican border crossing of Sasabe is at the southern tip of Unit 36C, whose high point is 7,734-foot Baboquivari Peak. Some high-quality Coues deer inhabit hills and mountains, and several bucks have qualified for entry in Boone and Crockett Club records. Mule deer are found in the flat lowlands.

Hunters find some big Coues deer in this unit but also encounter U.S. Border Patrol agents, drug smugglers and illegal immigrants. Bring a shotgun for a quality Gambel and scaled quail hunt.

Low country is mostly flat with ravines, while higher terrain features mild foothills, rocky hillsides, canyons and steep, rocky mountains. Hiking can be difficult, especially in hot weather.

Mesquite and grasslands along with Sonoran desert scrub and cactus are at low elevations. Oak, chaparral and ocotillo cactus dominate the land at high elevations.

Some roads are closed on private ranches, so hunters must hike to reach some good hunting areas. State trust land, BLM property and Buenos Aires Wildlife Refuge are open to big game hunters. Most land is open to hunting because of stewardship agreements that state officials have negotiated with various ranches. Several mandatory sign-in stations are situated throughout the unit. Each one is independent of the others, meaning you must sign in to hunt each ranch. Hunters who fail to sign for access are subject to prosecution for trespassing. Some private landowners allow access across property to public lands.

Camping is allowed on Buenos Aires Wildlife Refuge as well as state land and the Coronado National Forest. Lodging is in Tucson, Three Points, Sasabe and Arivaca. There are no developed campgrounds.
