Napa Valley

To the west is the Sonoma Valley, to the east is Lake Berryessa and Yolo and Solano Counties, and to the north Lake County. Napa Valley is actually just one of many valleys in Napa County, but it's by far the largest and best known. The valley itself is about 30 miles long and ranges from one to five miles wide.

Napa County has a population of about 110,000 people, and five incorporated cities. North to south, they are: Calistoga, St. Helena, Yountville, Napa and, at the southern end, American Canyon. Angwin, Deer Park, Lake Berryessa, Rutherford and Oakville are communities with post offices but aren't actual towns.
