Chatsworth is a suburban neighborhood in the northwestern San Fernando Valley, within the city of Los Angeles, California. Bordered by Porter Ranch to the north, Northridge to the east, and West Hills and Canoga Park to the south, it runs up to the Santa Susana Pass at the Ventura County line, where the San Fernando Valley meets the Simi Hills. Covering about 15 square miles, it is one of Los Angeles's larger and lower-density neighborhoods, with roughly 37,000 residents. The neighborhood's defining feature is its dramatic landscape. Stoney Point, a cluster of ancient sandstone boulders that rises abruptly from the valley floor, is a local landmark and a popular spot for bouldering and rock climbing; its caves and alcoves hold a long history, and the formations have served as a backdrop for countless film and television productions. Chatsworth's Western-movie heritage runs deep, rooted in the old Iverson Movie Ranch and the area's ranch-and-film era. Chatsworth retains a distinctly equestrian and outdoors-oriented character rare in Los Angeles. Many homes sit on larger lots with horse-keeping zoning, and a network of bridle paths and trails connects neighborhoods to Chatsworth Park South and the adjacent Santa Susana Pass State Historic Park, a 680-acre preserve straddling the county line that is popular with hikers and equestrians. The Chatsworth Nature Preserve and nearby parks add open space. Transportation links are strong. The Chatsworth Transportation Center is served by Metrolink's Ventura County Line and Amtrak's Pacific Surfliner, offering rail access to downtown Los Angeles, Ventura County, and beyond, with a planned connection to Metro's D Line. The 118 Freeway runs along the neighborhood's northern edge, and Topanga Canyon Boulevard provides a north-south route. Schools are part of the Los Angeles Unified School District, with local campuses including Big Springs Elementary, and private options such as Sierra Canyon School in neighboring Porter Ranch are nearby. The neighborhood's mix of open space, rail access, and a semi-rural feel makes it a distinctive corner of the city, appealing to those who want room, trails, and a quieter pace without leaving Los Angeles.
