The length of the valley (Napa to Calistoga) is serviced by two roads running parallel: Highway 29 and, 2 miles away to the East, the Silverado Trail. During commute times and on weekends, Highway 29 is often bumper-to-bumper. However, the Silverado Trail is not as crowded. The Silverado Trail also has many charming wineries. It is on higher ground and you can often catch a glimpse of a favorite winery in the valley. Don't worry, this is a narrow valley; therefore, a quick trip to Highway 29 attractions is possible on the many short roads crossing between the two highways (Trancas, Oak Knoll, Yountville Rd., Oakville Rd., Zinfandel Lane, Bale Lane, etc.).

I have a suggestion for a day trip to the ocean. Travel north on 29/128 to big highway 101; back to 128 in Booneville and a scenic ride all the way up to Albion. This is a long ride. There are other shorter routes available to the north coast through Santa Rosa. If you get to the coast: the farther north above Bodega Bay you travel on Highway 1, the better the scenery. Take a warm jacket/or layer some clothes as the north coast is chilly (cold wind daily and night and evening fog) in the summer. Have a wonderful trip.
