The Canelo Hills are a long low ridge of rounded hills extending about 20 miles from northeast to southwest. The hills connect the Santa Rita Mountains to the northwest, Patagonia Mountains to the southwest and Huachuca Mountains to the southeast. Although the Canelo Hills rise relatively little above the desert floor when compared to many Sky Island mountain ranges, there is still enough elevation change to create a dramatic change in vegetation. The Canelo Hills support some of the best evergreen oak woodlands (encinal) and grasslands in the Sky Islands region.
- State Highway 83 Scenic Drive: Arizona State Highway 83 is a paved route that winds through the Canelo Hills from Sonoita to Parker Canyon Lake. This is an area of rolling hills and shallow canyons vegetated with evergreen oak woodlands and grasslands. In years with a wet winter, the spring wildflowers (late February to early April) can be spectacular.
- Cienega Wetlands: A cienega is a desert wetland that forms where a spring spreads out and flows slowly creating a broad marsh. Cienegas attract all sorts of wildlife and support numerous rare plants. Because sources of surface water are scarce, cienegas were usually homesteaded and many of them are now privately owned. Some privately owned cienegas in the Canelo Hills are now being managed as nature preserves.
