The deep, verdant valleys of Gerês, desolate landscapes of the Serra da Peneda, jagged peaks, this grandiose region in the far north of Portugal is all about contrasts. The purpose of this national park is to protect these leading landscapes and archaeological sites, as well as its highly diverse flora and fauna (stags, wild ponies, golden eagles). Its farming population, whose traditions remain very much alive, live here in harmony with the environment. See it all on foot.
