About Howell

Mountain

Howell Mountain, located between Angwin and St. Helena, is a rural and wine-country Angwin neighborhood with forested ridgelines and vineyard roads. The character concentrates along Howell Mountain Road near the Angwin Plaza area, where tasting rooms, a market counter, and porch-side conversations set the pace. Homes range from secluded cabins and ranch-style properties to contemporary vineyard estates tucked behind oaks and madrone. The landscape shifts from sunlit vine rows to shaded trailheads, with long views toward the Napa Valley floor. Landmark wineries such as Dunn Vineyards, O'Shaughnessy Estate Winery, and Robert Craig Winery act as cultural anchors for the mountain.
