Three powder fields at the Grands Montets often untouched by the masses, which connect the top and the bottom of the mountain so you can ride/ski for 12km (2km vertical) non-stop; nice! See how many you can do in a day.
From the Les Grands Montets Cable Car, the Hearse Chair, or by traversing from the Bochard Bubble, drop towards Argentiere high on the glacier wall (stay high at all costs). Keep left at the little restaurant/hotel, and then drop towards the trees keeping your direction (if not go left), and then connect back to the home run.
Is this your business?
