Visit California’s first wine country. Wine Country doesn’t get more real than Sonoma Valley, whose rich soils mark the birthplace of California’s wine industry. It’s also the closest wine region to San Francisco, just 45 miles north of the Golden Gate Bridge. Sonoma Valley encompasses a rolling patchwork of vineyards, quaint farms and 13,000 acres of scenic parkland. In the center of town, the eight-acre Sonoma Plaza is a National Historic Landmark, strewn with spawling shade trees and bordered by carefully preserved adobe buildings.
