The Dry Creek Valley west of Healdsburg centers is named for a willow-shrouded tributary of the Russian River that flows through the vineyards that blanket this valley. Dry Creek Valley is especially known for Sauvignon Blanc and Zinfandel, the latter produced by very old vines planted by Italian immigrants at the beginning of the 20th century. While many vineyards converted to fruit production during Prohibion, a few vineyards survived and their zinfandel vines produce even today. This region is a little off the beaten path, providing less expensive tastings and more interaction with winery staff at its many wineries. Cyclists also loop around Dry Creek Valley, taking advantage of the quieter country roads on the west side. A number of small family farms, orchards and produce stands are also located in Dry Creek Valley, and many of the wineries offer picnic areas with spectacular views of the vineyards.
