You better be comfortable with bobby pins. Incredibly technical and exposed line with rocky and technical hairpins until the trail becomes more gradual. The difference in height and the exposure make this area a place where any fall is to be absolutely avoided. It is definitely a route for experienced cyclists. This section of the trail is also a popular hiking route, so expect some hikers to use it. Be kind to them, share the path and respect it.

Hillside area under the Bec de Lachat and the Becs Rouges. In this peaceful sector, you will discover winding paths, native flora and fauna, as well as fantastic views of the valley and the Argentière and Le Tour glaciers. The trails here are shared, so respect other users.

The main focal point of the Grands Montets ski area, with restaurant services, and the base of many ski lifts. The area offers a superb view of the Aiguilles Rouges, as well as the Argentière glacier. In the past, the area was connected to the valley by a cable car to Argentière, but following the fire in recent years, it can now only be accessed by putting in the effort yourself, or from the Plan gondola Joran.

Let's not be afraid of words, the Col des Posettes is a trail-running paradise. It is not for nothing that the runners of the UTMB (Ultra Trail du Mont-Blanc) like this passage so much. You are on a short rolling section with unforgettable panoramas.
