The beauty and the natural wealth of the Ordesa Valley originated the creation on August 16, 1918 of the National Park, the second oldest in Spain. After its extension, it was declared World Heritage by the UNESCO, as well as Special Protection Area, Site of Community Importance and Biosphere Reserve. It is a valley with spectacular landscapes, special structure and forms determined by its calcareous nature.
In the Ordesa Valley floor, between walls of more than a thousand metres, the Arazas River flows down some beautiful waterfalls surrounded by dense and colourful forests: the waterfalls of the Estrecho and the Cueva, the Gradas de Soaso and the famous Cola de Caballo. In the vertical walls there are “bands”, horizontal ledges where narrow and vertiginous paths run, that allow us to go down the high valley and access to the high areas of the National Park. In this place stands out the Path of Hunters, Faja Pelay, the Cirque of Carriata, the Tozal del Mallo, the Cascada de Cotatuero and the Clavijas de Cotatuero.
