It was a wonderful experience! We had a great and friendly guide, Frieda. She took us to 2 wineries. We enjoyed wine tasting and chatting there. During biking, Frieda explained some history of wine which is very interesting for me. The trail was not hard, but perfect for enjoying nature and view. If you join this tour, you can enjoy the beautiful view of Sonoma county, delicious wine, and conversation with Frieda! Hopefully, I can join another tour again in the near future ;D!
