Ordesa y Monte Perdido National Park.

Escuaín Gorge

The Escuaín Valley, or Gorge, is the less known and smallest valley of those comprised in the National Park. Nevertheless, its dramatic scenery is worth to be mentioned, especially its gorges and narrow passes.



Large meadows and fields were open amid the ancient forest. Escuaín is home to a rich nature: an awesome group of caves and pit cave, especially in the Gurrundué area, a large mixed forest on the northern slope of the Castillo Mayor and an exceptionally diverse fauna, especially in the case of the bearded vulture.

As in other areas of the National Park, the area around Tella and Revilla is constituted by limestone bedrock of Cretaceous origin, which caused the formation of several caves, pit cave and gorges.

The Yaga River, fed by several springs, streams and gorges, drains the Tella Valley, also known as the Puértolas Valley, shaping a winding gorge full of rocks and vegetation. A natural paradise for the bearded vulture, which is easy to be sighted in this area.



The Gorge hides at its bottom the upper course of the river, constituting a deep cleft in the limestone bedrock. Its head comprises a group of hanging cirques, full of cracks and pit caves where vegetation is substituted by stone and water spraying down from gorges which seem to have been carved by a skilful artist; or it is drained into the ground, shaping a subterranean world of caves, wells, galleries and springs, before flowing, later, into the Yaga River.



It is a karstic paradise, so awesome on its surface as underground. Cave explorers consider Escuaín as one of their sanctuaries, with cave systems among the most important ones in the World. On the other hand, people looking for open spaces will find a traditional and colourful valley, full of surprises.
