Santa Monica Mountains - Roads and Access

Roads and Access

Cahuenga Pass, present-day site of U.S. Route 101, is the easiest pass through the range connecting the Los Angeles Basin to the San Fernando Valley. In the 1800s, two battles were fought there, and the Treaty of Cahuenga was signed nearby. In the heyday of Hollywood movie studios clustered on both sides of it. Sepulveda Pass is the main north-south pass to the west, connecting the Westside to Sherman Oaks via the San Diego Freeway (I-405). Further west are Topanga Canyon Boulevard (SR 27), Laurel Canyon Boulevard, Malibu Canyon Road, and Kanan Dume Road. Mulholland Drive runs much of the length of the Santa Monica Mountains, from Cahuenga Pass to Woodland Hills while the Mulholland Highway runs from Woodland Hills to Sequit Point at the Pacific Ocean. The eastern end of the range, located in the City of Los Angeles, is more intensively developed than the western end of the range. The city of Malibu runs between the coast and the leading mountain ridge, from Topanga Canyon in the east to Leo Carrillo State Park in the west. The term Malibu Ozarks is sometimes used derogatorily (or ironically) for the unincorporated part of Malibu beyond the leading mountain ridge and lacking an ocean view; the term is often used synonymously with "818 Malibu" (referring to the less desirable San Fernando Valley telephone area code prefix).
