The Douro River is one of the most important rivers on the Iberian Peninsula. It rises in northern Spain and flows in a generally westward direction, emptying into the Atlantic Ocean at the Portuguese city of Porto. In this drone video by contributor Psantos02, you'll get a look at the waterway as it begins its journey across Portugal. The video was shot in the area of Foz Côa, which is part of the Guarda district of northeastern Portugal. The Guardal District is part of the country's Norte region.
