Be careful, if in summer it is a fairly easy passage, in winter, as the surrounding slopes are steep, it is more prudent to have crampons

Ascent accessible to all but requiring sure steps in the mountains. May be a little more difficult for people prone to vertigo. It may be necessary to secure the little ones with a lanyard (ledges). Some passages require help with your hands (semi-climbing) but the holds are beautiful and accessible to all. The descent by the same path is undoubtedly less easy and should be reserved for those in the know.
