The PGNP is characterized by the constant presence of water and can be crossed (in part) by road or through its numerous pedestrian rails. With an area of about 72,000 ha, it is spread over five municipalities: Melgaço, Arcos de Valdevez and Ponte da Barca in the district of Viana do Castelo, Terras do Bouro (where it occupies 55.7% of the total park) Braga and Montalegre in the district of Vila Real.
GERÊS-XURÉS TRANSBOUNDARY PARK
On the other side of the Portuguese border, in Galicia, PGNP has continuity. On July 31, 1997, the Cooperation Agreement between the PGNP and the Baixa Limia-Serra do Xurés Natural Park, Lóbios Municipality, in Spain, was ratified. The two parks constitute the Gerês-Xurés Transboundary Park with a combined area of approximately 91,000 hectares.
The creation of this Gerês-Xurés Transboundary Park reveals the work that has been developed in order to join efforts to safeguard the natural and landscape values, since the fauna and flora knows no frontiers.
