Clinging to the northern border of Spain, the park, known simply as Gerês, is a sight not to be missed. Created in 1971, the area is the only natural reserve of this kind in Portugal. Just put on a pair of comfy hiking boots and let yourself be delighted in its turquoise waters, oak-clothed mountains and murmuring winding rivers. The reserve provides shelter for the endangered species of the Iberian wolf and has also helped preserve unique sets of ecosystems. Trekking the moorlands and lush pine forests you shall also feed your hunger for archeology for there are some Iron Age archaeological sites on the way. For some idyllic rural atmosphere and local peculiarities, head for the northwest!
