Do a double vertical kilometer on this route between the valley and the summit of the Grand Coin! 2200m of positive vertical drop await you, crossing all the strata of the Alps.
This itinerary offers a wide range of landscapes, from valley floor forests to alpine pastures and high altitude mineral areas. It's a superbly demanding itinerary, but ideal for challenging yourself or for training with an elevation gain. Once at the top, you can continue on the Grande Boucle back to the starting point.
