Enjoy a day of exploring Napa Valley or Sonoma Valley on a private tour for just you and your group. You can admire the vineyard scenery as a driver takes you to local wineries, which can be chosen for you or you can choose based on your interests. Learn about the winemaking process from grape to glass, and enjoy tastings of different varietals, if you wish. Tours typically consist of three to four wineries, plus time for lunch (own expense). Please note, wine-tasting fees are not included.
