Having done the wine trolley tour in Napa, I also booked the trolley tour in Sonoma. Dillon was a terrific driver/guide - very knowledgeable, experienced and friendly. We visited 4 wineries, all quite different but Berringer was my stand out favourite, definitely a winery tour to remember ! Again, the lunch provided was delicious. Like Napa, touring wineries on your own is not easy, save yourself the hassle and go with Dillon, money well spent !
