Napa valley is consider one of primer wine region in the world! Today at Napa there are over 500 winery/vineyard.
I highly recommend to stop by the visit center first to get a valley map which will show you which winery is at which location. Also the map will show you which winery is open to the public.
My first stop was alpha omega. It’s pretty view of the grape vine right in front of you while you can enjoy a glass of wine.
Castello di Amorosa
Very pretty castle and can wine taste inside
Great tasting experience
