Description of the route

From the square in the municipal capital, follow the dirt track that goes up to the hamlet of Crépin and continue towards Alpe Foresus (itinerary 4). A few dozen metres before this pasture, at the crossroad with the road from Alpe Charavellessaz, take route 4 which goes right, then left, and cross a wide plateau heading towards Alpe Cleyva Bella. From here, continue up until you come to a crossroad with Alta Via 1. Take the right branch and go up a small valley at the top of which you find Col de Nana.
