The summit of Monte Perdido (3355 m), located in Spain, lies hidden from France by the seemingly impenetrable peaks of the Cirques of Gavarnie and Estaubé.

The mountain forms part of the Monte Perdido Range and is located in the Ordesa y Monte Perdido National Park, in the western part of the Pyrenees, in the community of Aragon, Spain.

The route starts near the village of Torla, Aragon, at the Ordesa Valley and ascends the Cirque de Soaso towards the Refuge of Góriz before the stiff climb to the summit.

In the 1970s work began to build a dam in the nearby Añisclo Canyon with the objective of creating hydroelectric energy but institutions and citizens demonstrated against this and succeeded in stopping it.
