Oak Park is an unincorporated community in southeastern Ventura County, California, set in the Simi Hills at the eastern edge of the Conejo Valley. It was developed beginning in the late 1960s, when a single road from Agoura Hills in neighboring Los Angeles County provided the only access, and it has grown into a community of roughly 14,000 residents within about 5.3 square miles. Oak Park's residents chose to remain unincorporated rather than annex to Thousand Oaks or incorporate as a separate city, a decision that continues to shape the community's governance and identity. Services are provided by Ventura County, while a strong community association and the local school district anchor civic life. The community is best known for its schools and its natural setting. Oak Park Unified School District is widely regarded as one of the higher-performing districts in the region, a major draw for families. The surrounding hillsides and open space are threaded with hiking and equestrian trails, and the community's master-planned neighborhoods are set among oak-dotted hillsides and preserved open land. Oak Park's location is a central asset. It borders Agoura Hills, Westlake Village, and Thousand Oaks, placing the community minutes from the 101 Freeway corridor and the employment, shopping, and cultural amenities of the Conejo Valley. This position also offers access to the western San Fernando Valley and, via the 23 Freeway, the broader Ventura County coast. The community's low-density, hillside character and carefully preserved open space give it a distinctive, scenic quality among Conejo Valley communities, and recreational access to the Santa Monica Mountains and nearby regional parks further defines its appeal. Oak Park suits families and professionals seeking top-rated schools, a quiet suburban setting, and proximity to the region's major job centers.
