From the top of the Charmillon-Balme chairlift, traverse over to the Col de Balme. Climb up the ridge heading south-west which leads to the Grandes Autannes. The climb is a bootpack which gains 500 meters and follows the ridge line. The ridge is technically easy, however there are a few somewhat exposed steps and crampons may be useful. The summit of the Grande Autannes is a fantastic spot from which to take in the views over the Le Tour Glacier and the Aiguille du Chardonnet and out across the expanse of the Swiss Valais.

Ski down rolling and open terrain into the Trient valley. There are many possible variations depending on snow quality and cover. The steeper trees on skiers’ right can hold good snow. Once in the valley it is low angle and easy to ski. However, be aware that it can be a major terrain trap and is exposed to avalanches releasing from above. From the village of Trient it is possible to get public transport back to Vallorcine or eventually Chamonix.
