The cirque de Gavarnie is one of the biggest sites in the Pyrenees and one of the most frequented. The well-known brèche de Roland gives access to the summits of the circus, to the Monte Perdido, to the Taillon, to the Aragonese valleys aso. Excursionists who used to bivouac in the sector contentaient de l'abri Gaurier ou Villa Gaurier : a cave located in the wall, near la Fausse brèche, at the foot of pic Bazillac, discovered and arranged by abbot Ludovic Gaurier in 1906, who gave it its name and which was later arranged in 1911 by le Club alpin français, but which remained a stark comfort.
