About 128 Ridgecrest Rd

The King Mountain Estate is a rare gem nestled in Marin County, offering 140+ acres of unparalleled privacy, breathtaking panoramic views, and endless opportunities to create a legacy estate property like no other in the San Francisco Bay Area. Imagine building your dream compound, adjoining hundreds of thousands of acres of open space, yet just minutes from urban conveniences. The 30+ acre building envelope is on the ridgeline atop King Mountain, enjoying 360-degree views of the city of San Francisco, the East Bay, and Marin, as well as unobstructed views of the Bay, Bridges, and of course, Mt. Tamalpais. With approvals for a 27,500+ SqFt estate, this secluded paradise is more than just a piece of land-it's a canvas for visionaries to craft something extraordinary. And while King Mountain Estate enjoys access to public utilities, it also has its own source of water and is perfectly suited to create sufficient levels of solar energy to comfortably power the future compound, allowing for an off-the-grid lifestyle that simply cannot be replicated anywhere else in the Bay Area. In addition to Redwood Groves, Madrones, Oaks, and other native Flora and Fauna, the land enjoys direct access to hundreds of miles of hiking and riding trails. It truly is the Bay Area's ultimate Unicorn.
