While driving around Napa, we saw this Chateau from the road and decided to investigate. While we did not take any formal tours or try out the food at the Domaine Carneros Winery, we got to look around the beautiful grounds(of course every winery you find in the Napa Valley area will mostly have beautiful grounds). We never got a chance to go back to the Chateau, but I recommend you check it out if you have the time.
