Posets-Maladeta Nature Reserve

The Posets-Maladeta Natural Park is a mountain range located in the northeasternmost part of the Aragonese Pyrenees. This area is home to some of the highest peaks on the Iberian Peninsula. It is one of the most representative areas of the high Pyrenean mountains and boasts a high level of ecological, landscape and natural diversity.

The natural park extends across the municipalities of Benasque, Gistaín, Montanuy, Sahún and San Juan de Plan. It is located at a high altitude, between 1,500 meters at the bottom of the valley and 3,404 meters at the summit of Aneto (the highest point in the park and the second highest in mainland Spain), making this sector of the Pyrenees Mountains one of the most important representatives of the high mountain ecosystems of the Iberian Peninsula. The valleys of glacial origin (Estós, Eriste, Vallibierna, Gistaín) are very humid, rich in timber (pine, fir) and wildlife. These lands are inhabited by bears, otters, chamois, deer, roe deer, wild boar and birds of prey (golden eagle, vulture, bearded vulture).
