Perched atop one of Marin County's most spectacular private ridgelines, this once-in-a-generation legacy estate offers an extraordinary opportunity to own over 54 acres of unparalleled beauty just minutes from San Francisco. Behind private gates, the property commands breathtaking panoramic views spanning the San Francisco Bay, city skylines, rolling hills, bridges, and unforgettable sunsets. The estate features three exceptional residences thoughtfully positioned for maximum privacy, including an impressive main residence, an elegant guest home, a detached studio, private fitness pavilion, multiple garages, and an array of ancillary structures including a pool house ready for a pool to be built. Designed for those who value privacy, prestige, and possibility, the property offers a rare combination of luxury living, multigenerational flexibility, executive retreat potential, and expansive grounds unlike anything else available in Marin. The three legal parcels provide exceptional long-term value and future opportunities, while the park-like setting creates a peaceful sanctuary only moments from world-class dining, yachting, hiking, and the cultural amenities of Marin and San Francisco. Whether envisioned as a private family compound, luxury retreat, or one of Northern California's most iconic estates, 300 Margarita Drive represents an irreplaceable offering where scale, privacy, and extraordinary natural beauty converge. A truly rare opportunity to own one of Marin County's landmark estates.
