Property Description
The Summit is a world entirely of its own, offering an unmatched level of privacy, seclusion, and self-sufficiency in one of Northern California's most breathtaking natural settings. Surrounded by panoramic views stretching from Mt. Tamalpais and Mt. Diablo to San Pablo Bay and the San Francisco skyline, the estate was designed as a private retreat for those seeking space, independence, and complete escape from the outside world. Rolling meadows, lakes, canyon systems, swimming holes, native oak groves, and millions of seasonal daffodils create an environment that feels both expansive and deeply serene. The property includes multiple residences, a 12-car garage, barns, and three state-of-the-art greenhouses, allowing for multi-generational living, private events, agricultural use, or wellness retreats. Extensive infrastructure, water resources, backup power systems, and fire mitigation measures provide a rare sense of security and long-term sustainability. The Summit presents a once-in-a-generation opportunity to own a sovereign estate where privacy, natural beauty, and self-reliance exist in complete harmony.
