FATMAP difficulty grade
Description: It runs through the entire valley floor - first on a paved road and then on a dirt road.
At the bottom go up - push - following the TMB signs for the ref.
Bonatti. Arrived at a mountain pasture - also visible from the valley bottom - the path becomes a long ups and downs that first leads to the ref.
Bonatti and then to ref.
once arrived at Bertone, you can go down to Courmayeur from the path that starts from the refuge itself (attention: initially sooooo steep).
Needless to say, it is to do absolutely in good weather © because the view is BREATHTAKING! Â
