Quick Overview

Napa is the gateway city to California's most famous wine region, sitting at the southern end of the Napa Valley about 50 miles north of San Francisco. The area has several motorhome dump stations, with some offering free access. You'll find service point facilities at local motorhome parks and campgrounds that cater to wine country visitors. Napa Valley draws RVers from all over the country who want to tour the renowned wineries while keeping their rig as a mobile base camp. Highway 29 runs the length of the valley through St. Helena and Calistoga, while Highway 12/121 connects to Sonoma and the south. The valley roads are manageable for RVs on the main routes, though some winery back roads get narrow. Having a reliable sanitary service point in the Napa area is essential for anyone spending a few days exploring the valley's world-class wines, acclaimed dining scene, and beautiful vineyard landscapes. Without a local dump option, you'd be driving all the way to Vallejo or Fairfield just to handle your tanks, which eats into your wine tasting time.

Sep - Oct

50-88°F

Crowds: High

Harvest season is the most exciting and most crowded time in the valley. Crush events and grape picking everywhere. Reserve early and plan dump visits for weekday mornings.

Explore the Napa Area

Wine country gets crowded on weekends, especially during harvest season from September through October, so plan your dump runs and driving for mid-week when traffic is lighter. Many Napa wineries have limited parking that won't accommodate larger rigs -- consider leaving your motorhome at camp and using a smaller vehicle for winery visits along the narrow valley roads. Fill your water tanks in town since options thin out as you head north through the valley. The Napa Valley Wine Train is a unique experience, and the Oxbow Public Market downtown has excellent food vendors and local produce worth checking out.
