If instead of staying at the waterfall you go two more minutes you will have a spectacular photo of the Aneto glacier.

The highest peak in the Pyrenees mountaineering region.

Very nice steep transition from F to E. The path is laid out in tight bends and hardly exposed (just steep). Coming from France, the gap looks insurmountable. In mid-June there may be some old snow fields that can be hard in the morning. Caution is advised; very light crampons, such as those available for trail running shoes, may be helpful.

This mesmerizing plain is an ancient filled lake from the immense glacier that occupied the entire valley thousands of years ago. A special place with a particular sound, as if silence occupied the space in a tangible way.

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').
