A wonderful day trip from the Inn is to visit Sonoma County. It has a slightly more laid back vibe then Napa but still is home to some of the best wineries in the Country.
We are happy to provide you with some discounted tasting cards when you check in as well as suggestions on where to go. We also love this Sunset Magazine guide:
