Porto River Cruises
Porto's sea port is located in Leixoes at the mouth of the River Douro and five miles north of the city, whilst river cruise vessels can access Oporto directly. Oporto is the hub of the port wine trade, and vineyards line the shores of the river upstream. Old Oporto is a World Heritage Site with houses dating back to the 15th-century, a grand cathedral, a train station decorated with fine examples of Portugal's blue and white tiles and the remains of Roman city walls.
