A rented car or a hired driver is the most convenient way to get around Yountville, Calistoga, and Napa Valley. It is also advisable to book a flight to San Francisco International Airport, then rent a car and drive across the Golden Gate Bridge to Napa Valley. Estimate a total of 2 hours to reach your destination from the airport, costing between $100-$150 for a rental car.
Spend an extra day exploring the lesser-known side of Napa Valley or add another day to explore the city of San Francisco. Another option is to cut short the winery tours or omit visiting the Petrified Forest. If you have more time to spare, consider taking a hot air balloon ride over the vineyards or hike the Mount St. Helena for an unbeatable mountain view of the valley.
