The Napa valley is just about an hour north of San Francisco. It's a ideal place for a weekend getaway --food, wine, and sunshine. There are fun segway and bicycle tours that take you through the various vineyards in the area. If you are a big foodie, then you should not miss Yountville. All the restaurants here serve fresh local products. To dine at the world famous French Laundry, you'll need to book way in advance, sometimes, upwards of 3 months.
