Getting Oriented

The Napa and Sonoma valleys run roughly parallel, northwest to southeast, and are separated by the Mayacamas Mountains. Northwest of the Sonoma Valley are several more important viticultural areas in Sonoma County, including the Dry Creek, Alexander, and Russian River valleys. The Carneros region, which spans southern Sonoma and Napa counties, is just north of San Pablo Bay, and the closest of all these wine regions to San Francisco.
