Marvel at Porto's beauty, history and charms with a coach tour, photo stops and a cruise down the Douro River. A brief panoramic drive brings you into central Porto, a UNESCO World Heritage Site noted for its architecture and many important ecclesiastical buildings. One such building is the Cathedral of Porto; built between the 12th and 13th centuries, it features a variety of architectural styles, including Romanesque, Baroque and Gothic. You'll pause for photos then proceed to the Church of Clerigos, a Baroque and Rococo building from the 18th century. For a different perspective of Porto, you'll board a boat and cruise down the Douro River to the city of Vila Nova de Gaia, the same route wine traders used for hundreds of years. Here, you'll disembark and visit a well-known port wine cellar, learn about the winemaking process and sample this regional specialty before returning to the ship.
