We will be visiting Sonoma/Napa next weekend staying at MacArthur Place in Sonoma. This is our 2nd trip to wine country. We have never been to Calistoga before and saw a picture of the Castello di Amorosa Winery and it looked beautiful. Thinking about going and wondered what would be the most scenic route to take and if anyone has any other must see stops along the way. While we do love wine what is even more important are beautiful wineries and picturesque scenery. Any opinions or suggestions will be greatly appreciated. Thanks in advance!!
