The country’s oldest roots are said to be found in its northernmost region, and this place is indeed a diverse snapshot of Portugal’s cultures and history. The Douro River carves through wine country and the cliffs and hills of Douro Valley to end up in Porto, a vibrant port city with a proud cultural heritage. Douro Valley is the hotbed for Portuguese wine production and is most famous for its variety of port wines, all pairing perfectly with hearty meals of meats and fish.
