One of my favourite things of this program includes the magnificent views we get over the Belledonne during day 1. Then, on day 2 we discover some beautiful summits: Etendard, the Pic Bayle and the Pic Blanc de l’Alpe d’Huez. There are even more stunning sceneries, including the emblematic Grand Pic de la Meije.
