This easygoing trail skirts the western side of the valley at an altitude of around 2000m, commanding terrific views across the valley to Mont Blanc. To avoid hoofing it 900m up the slope, take the Téléphérique de la Flégère from Les Praz or the Télécabine de Planpraz from Chamonix; walking between the two takes about two hours.

The trail links Col des Montets (12km northeast of Chamonix) with Les Houches (8km southwest of Chamonix).

A variety of other great trails begins at the top of the Planpraz and Flégère lifts.
