Beautiful area and great choices of wine farms. It was clear that the tour guide knows area and history, but unfortunately he could not make it flow, jumping stories/history, repeating them and often we were lost with what he was talking about. Its worth sometimes not to have somebody talking all the time.
Excellent wine tour, city tours, and sightseeing of the areas. We highly recommend this tour if you want to see the areas, taste wine, and experience Sonoma.
