The highest peak in the Pyrenees and the one everyone wants to climb. Its demands are more physical than technical, with the exception of the Mahoma Pass, not suitable for those with vertigo, and the Aneto Glacier, which is recommended to avoid in the middle of summer when the hard centuries-old ice is exposed and landslides increase due to melting. At the top you will find a gigantic metal cross, a statue of the Virgen del Pilar and a small bust of San Marsial, patron saint of Benasque. Each of them installed by different groups that want to make their own a piece of this colossus that, although it is difficult to believe, went unnoticed for centuries in the shadow of the apparently more prominent Tuca de la Maladeta (from the Occitan "Mall Hita", the 'high peak').

Aneto is the highest peak in the Pyrenees and the second highest in the Iberian Peninsula, with an altitude of 3,404 meters above sea level. It is located in the Posets-Maladeta Natural Park, in the Spanish municipality of Benasque, province of Huesca, autonomous community of Aragon. It is part of the Maladeta massif and, located in the Benasque valley, is made up of Paleozoic terrain of granitic nature and Mesozoic materials. On its northern face, starting at approximately 2810 m, is the largest glacier in the Pyrenees, with about 100 hectares of surface, which is, like many in the world, in clear regression as a consequence of climate change (it is estimates that in the last 100 years it has lost more than half of its surface, and that in 30 or 40 years it may disappear).
