Lucerne Valley is a census-designated place (CDP) and valley landform in the southern Mojave Desert, in western San Bernardino County, California. Geography The geographic valley is defined by the surrounding Granite Mountains, Ord Mountains, and San Bernardino Mountains. Lucerne Valley lies east of the Victor Valley, whose population nexus includes Victorville, Apple Valley, Adelanto and Hesperia. It is east of Apple Valley, and north of Big Bear Lake. Distant surrounding communities include Yucca Valley which lies east via State Route 247/Old Woman Springs Road, and Barstow, which is north via State Route 247/Barstow Road. The transportation nexus of Lucerne Valley is where State Route 247 and State Route 18 are connected by Old Woman Springs and Barstow Roads. The two highways do not have a direct junction. In San Bernardino County, Lucerne Valley's area is also identified as County Service Area (CSA) 29. While Lucerne Valley's "town limit" signs are within two miles of each other, the County Service Area Limits are much larger: in the west to Joshua Road (unpaved road east of Milpas Rd. on Hwy. 18), to the north at the height of Ord Mountain on Highway 247, to the south at the entrance to Cushenbury Canyon on Highway 18, and at Old Woman Springs Ranch as the eastern boundary.
