Starting point: Park in the car park at the Gresse en Vercors ski lifts.
Markings: Yellow-Green
(S) From the car park, take the path that passes under the Blayet ski lift. When you reach the first crossroads, turn right until you reach the top of the Blayet lift with its hut.
(1) From there, take the small path opposite that climbs into the woods. This is the first difficult part of the day, but the advantage is that you are in the shade for most of the climb. The last part is exposed to the sun and ends at the top of the Brisou ridge (beautiful view).
(2) From this point, descend towards the Col de l'Allimas and Serre Girardet until you reach the latter, which is indicated by a sign (crossroads).
(3) From there, do not follow the direction of Col de l'Allimas, but take the path on the right towards Tiolache and continue to this point (marked by a sign). This section runs through the woods without any difficulty.
(4) Head towards the Veymont hut. After 5 minutes, you will reach a crossroads with a path on the left marked with a yellow-green cross.
(5) Leave the yellow-green markings and take the path on the left. Cross the Barri and Chalanches ravines in succession. Follow the yellow markings to find the right path through the ravines. You will then reach the Ravin des Chauvines.
(6) Here you will find the path leading to Pas des Bachassons and Fontaine des Bachassons. Turn right. The slope is as steep as the first big hill of the day (Crête du Brisou) but longer. Be careful of sun exposure.
(7) Look for a place to camp (E).
