Robert Mondavi Winery, Napa
When you live in San Francisco or Silicon Valley, a trip to Napa is a must. We have been to this winery thrice. There is also a tour which ends with wine tasting. If you are here, then plan a day trip to Napa. There are tons of wineries to check out. You can also visit a spa or do hot air balloon ride. You can also read my other post on Napa here.
