Vines, wines and the people who love them are central to the economy of Napa Valley. Other treats for taste buds are in store, too, in the form of local olive oils, tomatoes, cheeses and mustard. The other senses are catered for with a vibrant visual arts scene. Rent a car or book a taxi or limousine to get between sights safely. The Napa Valley Wine Train offers an unusual way to experience the views and vintages. A relaxing array of spas and mud baths and the Old Faithful geyser are attractions in Calistoga.
