This loop takes you from the foothills of the Ecrins massif to the shores of Lake Serre-Ponçon, in a riot of colours.
Bold ascents and fast descents await you. Panoramic views, landscapes of grey marl, torrents and larch forests follow one another along this demanding route. You won’t have much time to catch your breath, so make sure you manage your efforts well.
