Bel Air is an affluent residential community in the hills of the Westside of Los Angeles. Together with Beverly Hills and Holmby Hills, it forms the "Platinum Triangle" of Los Angeles neighborhoods. Residences in Bel Air tend to be private and hidden from the winding roads of the community by dense foliage and gates. Properties range from modest ranch-style houses, to oppulant mansions on magnificent estates. Lower Bel Air boasts some of the most expensive homes in the community, and is a very exclusive zip code.
