Arribes del Duero Natural Park

Arribes del Duero Natural Park is a protected area in western Spain, covering 106.105 ha in the autonomous community of Castile and León. In this area the river Duero forms the national boundary between Spain and Portugal, and the Portuguese side is also protected under the Douro International Natural Park. The most notable characteristics of this natural space are its biodiversity and range of watercourses, which have eroded deep valleys and vertiginous precipices. This landscape is known as Arribes, which is where the reserve name comes from.

Fauna
The park is a Special Protection Area, recognised by European Union for birds such as the black stork.
