From La Renclusa via the Portillón Superior, the Aneto glacier and the Paso de Mahoma. A high-mountain itinerary with a glacier crossing.

The first documented ascent took place on 20 July 1842 by an expedition led by Platon de Tchihatcheff and Albert de Franqueville with local guides Pierre Sanio, Bernard Ursule and Pierre Redonnet.

El valle de Benasque está excavado en el batolito granítico de la Maladeta y en materiales paleozoicos (pizarras, calizas y esquistos). El modelado actual es glaciar: circos, cubetas de sobreexcavación ocupadas por ibones, morrenas, valles en artesa y umbrales rocosos pulidos. En el macizo de la Maladeta se conservan los últimos glaciares del Pirineo, en fuerte retroceso.

High granite mountains with glacial cirques, hanging mountain lakes, permanent snowfields and sharp ridges above the Ésera valley.
