It was founded in 1918 and comprises 15,608 hectares of park territory and almost 20,000 hectares of peripheral land, in which valleys, mountains and nature sites have become the last safe spot for a number of animal and vegetable species. The park’s four areas (Añisclo, Escuaín, Ordesa and Pineta) offer never-ending possibilities in terms of routes and hikes.
A wild 18 metre rocky canyon formed by an ancient glacier in its upper reaches and subsequently by the waters of the River Bellos. A narrow shear zone or fault, where one can see the inversion of the vegetative floor due to thermal inversion. The bearded vulture stands out as an example of the area’s fauna.
A glacial valley, which starts in the high plateau of Marbore from where the River Cinca descends forming the impressive Pineta waterfalls which give life to the great plains which form the valley floor. Also worthy of mention is the Pineta hermitage.
A tremendous rift of up to 1200 m of glacial origin subsequently shaped by the River Arazas, forming multiple waterfalls. Luxuriant beech forests give way to enormous alpine meadows at the top.
The least known of the park’s valleys, and birthplace of the last stronghold of the Bearded Vulture. An enormous limestone canyon with innumerable caverns, the fruit of karstic phenomenon. Worth mentioning is the emergence of Escuain with an 1100 metre drop.
