Mountain landscape presided by Monte Perdido.

The National Park is part of the Pyrenees and Monte Perdido National Park which was declared a World Heritage site in 1997 by the UNESCO. Since 1977, a part of the park has also been inside the Ordesa-Viñamala Biosphere Reserve.

This is an area of spectacular scenery with a landscape of towering summits. It has a wide variety of ecosystems with both an Atlantic and Mediterranean influence, which is what gives it such a rich and diverse flora and fauna. The scenery is dominated by the great massif of Monte Perdido (3,355 m), with the peaks of the Tres Sorores branching out into the valleys of Ordesa, Pineta, Añisclo and Escuain. This is a landscape of great contrasts: from the extreme aridity of the upper areas, where rainwater and thawed runoff waters filter through crevices and chasms, and green valleys with woods and pastures, where the water forms waterfalls and rushes through canyons and gorges.
