DOURO INTERNACIONAL NATURAL PARK
This Natural Park includes the natural border between Portugal and Spain, formed by the Douro and Agueda rivers, along 130km and within an area of 85.150ha. In this section, the valley of the river shapes a deep canyon with steep slopes, mainly cliffs.
In terms of fauna and especially birds, the Douro Internacional Natural Park is one of the most important areas in the national and even Iberian context. The bird fauna is the most representative group in this area, due to the great diversity and the occurrence of several endangered species, which hold here an important percentage of their nesting populations at national and Iberian level, of the 170 species recorded, 126 are nesting.
