You leave the main track the Colle del Lys on the left and you go to the right, along a valley with a moderate slope towards the Vincent Pass (4088 m). Just before reaching it you turn again to the and then up the northwest side of Vincent consisting of a uniform snow slope, not difficult and is usually well marked.
Only in the last part the slope becomes steeper (depending on snow conditions, it can sometimes be advantageous to turn around the last ramp on the left), but once you overcome the last meters of the slope you are finally on the top (2-3 hours). To go down you can follow the same way of ascent, you can go down along the east-southeast or the southeast ridge.
Difficulty: easy (limiting gradient: 35°)
Difference of level: 750 m
