Sonoma is a county, a city, and a valley, which can be confusing for visitors who aren't yet aware of the distinctions. Laid-back Sonoma Valley, California—with its focus on small family-owned wineries and farms that produce olives and other crops—is just over the hill from the more traditionally elegant Napa Valley. The main cities and towns in the valley are Sonoma, Glen Ellen, and Kenwood. The valley carries the most weight in the popular imagination of Sonoma wine country, but the county has a number of other grape-growing American Viticulture Areas (AVAs) as well. In all, there are more than a dozen AVAs in Sonoma County.
