San Diego County, California, has a varied topography. On its western side is 70 miles (110 km) of coastline. Most of San Diego between the coast and the Laguna Mountains consists of hills, mesas, and small canyons. Snow-capped (in winter) mountains rise to the northeast, with the Sonoran Desert to the far east. Cleveland National Forest is spread across the central portion of the county, while the Anza-Borrego Desert State Park occupies most of the northeast. Although the western third of the county is primarily urban, the mountains and deserts in the eastern two-thirds of the county consist primarily of a native plant community known as chaparral. San Diego County contains more than a million acres (4,000 km²) of chaparral, twice as much as any other California county. Other locations include Cabrillo National Monument, San Diego National Wildlife Management Complex, and numerous birding hotspots.
