The Hollywood Hills form the north barrier of the Los Angeles Basin. There has been extensive residential development in the Hollywood Hills since the 1920s. The area includes Mulholland Drive, Laurel Canyon, and Nichols Canyon and is dotted with the mansions of the rich and famous.
Traditionally, the designation “Hollywood Hills” comprised the hill neighborhoods north of West Hollywood and Hollywood proper and excluding the more westerly neighborhoods. However, in recent years the meaning has expanded to include areas such as Benedict and Coldwater Canyons.
