Westlake Village is a planned community that straddles the Los Angeles and Ventura county line. The city, located in the Conejo Valley, encompasses half of the area surrounding Westlake Lake. Much of Westlake Village is surrounded by open space, including hiking and horse trails, as well as the vast Santa Monica Mountains National Recreation Area. The town borders the Malibu hills, and is nine miles inland from the Pacific Ocean. Coastal breezes seep through canyons to allow Westlake to stay up to 10 degrees cooler and considerably less smoggy than nearby San Fernando Valley during the summer months.
Westlake Village is known for its affluence and secluded character, and is considered one of the wealthiest communities in the Greater Los Angeles Area. Other communities in the surrounding area include Thousand Oaks, Oak Park, Agoura Hills, Calabasas, Newbury Park, and Malibu.
