The Douro Valley is the origin of the famous port wine and the oldest demarcated wine region in the world.
Here, the wine grows on dramatic terraces leading to the Douro River and, due to how steep the terraces are, the grapes are still harvested by hand.
On a day trip to the Douro Valley from Porto, you’ll have time to take in a few mesmerizing viewpoints, attend a port tasting, take a cruise along the Douro River, and visit a town or two such as Amarante and its history.
