View of the Douro river. Near Freixo de Espada a Cinta, a town in Portugal, if you go towards Poiares, you'll find Penedo Durao viewpoint. There you will enjoy yourself with a stunning view of the river and "Arribes del Duero" natural park.
This side, where the panorama was taken from, is Portugal. The opposite bank is Spain, and in the middle, down in the river -natural border-, Saucelle Dam.
