Once in a lifetime, an opportunity emerges that transcends the ordinary definition of real estate. Glendale Ranch, a property spanning over 2,000 acres just 3 miles from Main Street, St. Helena, is one of Napa Valley’s last great private estates, a self-contained world of rolling oak woodlands, ancient Douglas fir forests, cascading waterways, and heritage vineyards that have produced legendary Napa wine for over a century. Glendale offers absolute seclusion and world-class accessibility. A sanctuary that has sheltered visionary stewards from the Younts to the Rutherfords. Astounding ecological diversity rivals any protected parkland in the region, making Glendale one of the most biodiverse private landholdings remaining in the Napa Valley. At the center of it all is the historic White House, built in the 1880s, perched atop a grassy knoll with soaring ceilings, wrap-around porches, and timeless grandeur. Three additional homes across 17 parcels make this an extraordinary opportunity for a private family compound. Water is among Glendale’s most extraordinary assets. A 7-acre private lake, ponds, wells, and the year-round Conn Creek with secured water rights collectively form one of the most robust water systems in Napa. Infrastructure, from 1.5 miles of paved roads to 5.5 miles of improved dirt roads and an extensive network of utilities and water, offers countless possibilities bound only by imagination. You are invited to become the next steward of Napa Valley’s largest and most irreplaceable estate.
