Park in the lower car park at Col du Coq on the Saint-Pierre-de-Chartreuse side.
(S/E) From the car park, look for a path that climbs alongside the old ski run (meadow) and follow it to the ridge.
(1) Take the path on the right that follows the ridge. Follow it to the edge of the forest.
(2) Turn left onto the path that winds through the forest and follow it. Ignore the path branching off to the left and continue straight on the same track until you reach the summit of Bec Charvet.
(3) Take the path to the west which descends into the meadow towards the ridges. Follow it until about fifty metres before the Col de la Faïta.
(4) Take the path on the right and follow the yellow and red markings ofthe GRP® Tour de Chartreuse.
You will then reach a junction with a forest track.
(5) Follow it for about a hundred metres, then turn right onto theGRP® trail. Stay on this trail, following the yellow and red markings, until you reach the car park at the start of the Col du Coq (S/E).
