Just north of Phoenix, right along N Cave Creek Rd. at the Desert Hills Trailhead, there is a parking area for the Phoenix Sonoran Preserve, and access to 9,600 acres of underdeveloped land. This portion of property is one of the newest additions to the Sonoran Preserve. The city of Phoenix has a master plan, their mission is to protect the plants and animals of the Sonoran Desert while creating access to the land that people love. These facilities include a large shaded fan for cooling off after spending time in the desert heat.
