Hidden Hills is an incorporated city and fully gated residential community in the Santa Monica Mountains of western Los Angeles County, immediately adjacent to Calabasas and the western edge of the San Fernando Valley. With a population of about 1,700, it is one of the smallest and most deliberately exclusive municipalities in the Los Angeles area, known nationally as a retreat for entertainment figures and others seeking privacy and acreage. The community was planned and developed in the 1950s by landscape architect A. E. Hanson, who laid out a pastoral neighborhood of winding roads, large lots, and abundant open space. It incorporated as a city in 1961 specifically to preserve its rural, low-density, and equestrian-oriented character against the suburban development pressure that was transforming the surrounding valley. That founding intent remains visible today: bridle paths and dirt walking trails run alongside many streets in place of sidewalks, and the community is enclosed by gates that limit access to residents and their guests. Hidden Hills is defined by its horse culture. Many properties include barns, paddocks, and riding arenas, and residents make use of an extensive network of community bridle trails and equestrian facilities. The streetscape is one of sprawling ranch-style homes, Mediterranean villas, and contemporary estates set far back on lots that typically range from one to three acres. The city is served by the Las Virgenes Unified School District, which ranks among the most highly regarded districts in the region and serves the neighboring communities of Calabasas, Agoura Hills, and Westlake Village. For homebuyers, Hidden Hills offers an unusual combination of acreage, equestrian lifestyle, gated privacy, and strong schools within commuting distance of the greater Los Angeles economy.
