East Gate Old Bel Air: one of the two main entrances, the East Gate is located at Beverly Glen and Sunset Boulevard. At its southernmost edge (where Copa de Oro Road meets Sunset Boulevard), East Gate Old Bel Air borders the campus of UCLA. At its easternmost edge, it borders Holmby Hills.
The second of the two main entrances, the West Gate is located at Bellagio Drive and Sunset Boulevard, opposite an entrance to UCLA
In general, the further one moves west from Saint Pierre Road to West Gate Lower Bel Air and north from Sunset Boulevard up the Santa Monica Mountains to Upper Bel Air, the smaller and the less flat the building lots and the more varied the styles and price ranges of the homes (with development fueled largely by postwar demand in the 1950s).
