The Águeda (pronounced as /pt-PT/) is a river tributary of the Douro River, that springs from the Serra das Mesas in Spain, in the autonomous community of Castile and León. It flows 130km (80miles) until it reaches the Douro River near Barca de Alva, Portugal. The Portugal–Spain border follows the Águeda for much of its course.
