Where legacy properties, open land, and unparalleled privacy come together to create one of Southern California's most extraordinary ways of life. Treasure Hill is set on approx. +20 Acres in the prestigious, private community of Hidden Valley, this exceptional upgraded ranch estate offers one of the area's most iconic settings. Sweeping, unobstructed views of the Santa Monica Mountains, rolling hills, open pastureland, and endless California sky. Privately gated and graced by mature oak trees and an abundance of open +20 Acre space, Treasure Hill Ranch is a private oasis that combines the character and scale of a legacy ranch estate with the comfort, wellness, and functionality of a modern private compound.The main residence is thoughtfully positioned to bring the surrounding landscape into everyday life. A separate guest house provides additional accommodations for family or visitors. The grounds include an expansive pool & spa overlooking the entire valley, a built-in BBQ, a pool house, a horse arena and turn outs, all creating a beautiful setting for gathering, restoring, and watching spectacular sunsets give way to star-filled evenings. The well-equipped barn is far more than equestrian infrastructure. It offers a tack room and offices, plus full living space with a bedroom, a full kitchen, and a sauna, ideal for staff, guests, extended stays, or a private wellness retreat of its own. Together, the residences, barn, and outdoor spaces form a self-contained compound shaped for how you actually want to live.

Continue the equestrian lifestyle, establish gardens and agricultural spaces, raise animals, pursue a more self-sufficient way of living, or simply hold the land as a private family legacy. This is a property that can be shaped around wellness, creativity, and connection to nature, without sacrificing comfort or scale. Beyond the property, miles of trails and open space lead into the Santa Monica Mountains. Despite its secluded setting, the estate is conveniently near Sherwood Country Club, Camarillo Airport, and the Conejo Valley, with Beverly Hills approximately 45 minutes away.
