The Ordesa and Monte Perdido National Park is located in the Oscense Pyrenees, entirely in the region of Sobrarbe, Aragon (Spain). It is divided between the municipalities of Bielsa, Fanlo, Puértolas, Tella-Sin, Torla and Broto. It receives an average of more than 600 000 visitors per year.
It covers 15,608 ha and the peripheral protection area has 19,679 ha. Its altitude ranges from 700 m in the Vellós River to 3,355 m in the Monte Perdido.
Without doubt, this park is a treasure of nature, with a remarkable geomorphology resulting from the action of the glacier, its vertical walls, its beech forests and its varied fauna.
La Brecha de Rolando (Breca Roldán in Aragonese, Brèche de Roland in French) is a narrow pass 40 metres wide and 100 metres high, located at an altitude of 2,804 metres in the Monte Perdido massif. According to a local legend, it was opened by Roland, Charlemagne’s nephew, while he was trying to destroy his Durandal sword by hitting it against the rock at the end of the battle of Roncesvalles.
The Monte Perdido (in Aragonese As Tres Serols) is the highest limestone massif in Europe. Its highest peak is the Monte Perdido at 3,355 metres above sea level.
