Reviews: Napa + Sonoma Plaza 1-Day Tour [Premium Small Group of 12]

Guest User2025-11-21

Our guide, Jamesli, was professional and funny. The itinerary was very fun and comfortable, allowing us to fully enjoy the beautiful scenery and fine wines. In one day, we visited two wineries with completely different styles, saw the Golden Gate Bridge from different perspectives, beautiful vineyards, and lovely rolling hills. We also received various sharing sessions full of history and interesting stories. Welcome to San Francisco! I hope you'll have the chance to visit a winery sometime. Choosing this tour added a wonderful chapter to my San Francisco travel memories. I'm so happy!!
