Willow Lake Ranch presents a rare opportunity to acquire approximately 174 acres across two separate legal parcels in the highly regarded Los Carneros region of Napa Valley. Offering scale, privacy, agricultural history, water resources, and significant estate potential, the property represents an increasingly hard-to-find combination in one of Napa Valley's most recognized wine-growing areas. Approximately 135.8 acres were previously planted to vineyard, providing a substantial agricultural footprint and strong potential for future vineyard redevelopment and replanting. Two reservoirs provide valuable water-storage infrastructure and further support the ranch's long-term agricultural use. An original farmhouse still stands on the property, marking an established residential setting and offering a compelling opportunity to create a new custom residence in its place. The homesite enjoys incredible views across the ranch and surrounding Carneros countryside, creating an exceptional setting for a private Napa Valley estate. One of the property's most significant attributes is its configuration across two separate legal parcels. Each parcel offers the opportunity for a residence, creating flexibility for a primary estate with a second home, a multi-generational family compound, or two distinct estate properties. The separate parcels also provide added flexibility for long-term ownership, estate planning, investment, or future disposition. Located in the Los Carneros region, Willow Lake Ranch combines substantial acreage, vineyard history, water resources, expansive views, and exceptional residential potential. Whether the vision is to establish a significant vineyard operation, create a private Napa Valley estate, or hold an irreplaceable agricultural property for the future, Willow Lake Ranch offers the setting and flexibility to bring that vision to life.
