About This Home
Luxury Live Auction – Bidding to start at $3,300,000. Final price subject to competitive bidding. Hidden Ridge Ranch spans ±20 contiguous acres across two parcels in the coastal foothills of North San Diego County, offering a rare combination of a private hilltop estate, productive agriculture, and equestrian infrastructure. The property features established avocado, citrus, olive, and pomegranate groves, along with a boutique vineyard planted with Cabernet Sauvignon, Petite Sirah, and Primitivo/Zinfandel. Cross-fenced pastures, paddocks, turnouts, a riding arena, and dual gated entrances support a wide range of equestrian and agricultural uses. At the center of the estate sits a ±6,000 sq ft Mediterranean-inspired residence with guest accommodations, expansive entertaining terraces, and an infinity-edge pool oriented toward sweeping 222-degree mountain and valley views, capturing dramatic sunrises and sunsets across the surrounding river valley. The adjoining ±10.55-acre parcel offers independent road access and additional flexibility for residential buildings, equestrian facilities, or expansion of agricultural operations, creating a contiguous estate-scale landholding rarely available in coastal North San Diego County. Properties offering this combination of privacy, acreage, agricultural production, and estate infrastructure are increasingly rare and often held for generations. Hidden Ridge Ranch is being marketed as a private estate landholding. Offered for sale at Harcourts Luxury Auction on March 26th. Historical photos online
