Ordesa National Park was created in 1918 and covers an area of 15,608 acres of high mountains. It runs entirely along the Ordesa Canyon, a glacier whose walls rise more than 800 meters from the valley floor. Access to Pradera de Ordesa (1,301 m) is open until the last day of June, by bus from Torla. At the bottom of the prairie, you take the path on the left. On the right, you cross through a forest of firs, beeches and pines. We also spotted Arripas cascade (1,400 m) and a fountain.
