I highly recommend this tour. Riding Segways is a very fun way to see the beautiful Sonoma countryside. Even if you've never ridden one, it is easy and intuitive to quickly learn.
We visited two excellent wineries and a local cheese factory. Our guide, Hunt, is a life-long resident of Sonoma, and it was obvious how much he loves the town and enjoys sharing it with visitors. His deep knowledge and personal connections in town really enhanced the experience. If I ever make it back to Sonoma, I will gladly do the exact same tour again.
