Posets-Maladeta Natural Park Nature · Benasque, La Ribagorza, Huesca The Posets-Maladeta Natural Park extends across the north of the Ribagorza comarca and the northeast of Sobrarbe, in the province of Huesca, covering the municipalities of Benasque, Gistaín, Montanuy, Sahún and San Juan de Plan. Declared in 1994, it occupies more than 33,000 hectares between 1,500 and the 3,404 metres of the Aneto, the highest peak in the Pyrenees, along with other summits such as the Posets, the Punta de Astorg or the Pico Maldito. It is home to the main Pyrenean glaciers, as well as moraines and glacial lakes such as those of Vallibierna, Cregüeña or Batisielles. At lower altitude grow rowans, hazels and birches, and higher up beeches, firs and mountain pine, among marmots, chamois, bearded vultures and golden eagles.
