The first, most direct and most frequented, runs along the impressive north face, in the vast cirque de Troumouse. The starting point is located at the Troumouse car park, at about 2,100 m. The ascent is a bit technical (PD), with two delicate passages : a first small wall (III-) that one needs to climb before arriving at the col de la Munia, then the cat's footstep (II) shortly before the summit ~ all this achieved in a spectacular high mountain landscape. After having reached the col de la Munia (at 2,853 m), the route leading to the summit is clear-cut, leading straight east, by a sharp ridge.
