Portugal's oldest national park where Atlantic and Mediterranean ecosystems meet beneath dramatic granite peaks
Peneda-Gerês National Park
Peneda-Gerês National Park is Portugal's oldest and only national park, established in 1971 to protect a spectacular mountainous landscape in the country's northern highlands. The park occupies approximately 696 square kilometres spanning the districts of Viana do Castelo, Braga, and Vila Real, forming a natural amphitheatre of granite peaks, deep valleys, and pristine rivers along the border with Spain. Its name derives from the two dominant mountain ranges—Serra da Peneda and Serra do Gerês—that anchor the protected area, complemented by the lesser but equally striking Serra Amarela and Serra do Soajo.
The park occupies a remarkable biogeographical crossroads where Atlantic and Mediterranean climate systems converge, creating a zone of exceptional ecological richness. The granitic mountain massifs, formed during the Variscan orogeny between 380 and 275 million years ago, have been sculpted by subsequent glacial activity into the dramatic U-shaped valleys, polished rock surfaces, and moraines visible throughout the highlands. These ancient rocks host a complex of watersheds including the Lima, Cávado, and Homem rivers, whose tributaries cascade through steep valleys creating numerous waterfalls that rank among the park's most beloved features.
Beyond its natural significance, the park encompasses a living cultural landscape where approximately 9,000 residents continue traditional agro-pastoral practices in scattered villages that have shaped the terrain for millennia. The region bears traces of human presence dating to 6000 BCE, including remarkable megalithic tombs and the well-preserved Roman road known as the Geira, which once connected the Roman cities of Astorga and Braga across these mountain passes.
