Directions: If you are heading north on Highway 29, continue through the town of St. Helena, past the Post Office to the last stop light in town. If you reach Beringer, you have gone too far. Turn left onto Madrona Ave. Go three blocks, and turn right onto Spring Mountain Road. Follow Spring Mountain Road to the very top (approx. 15min). Turn right at the Napa County Line, which is painted on the road. Then follow the small yellow signs to the winery.
