1
Du Carri Pass (alt. 1202m), leave to the left of the cross-country ski center following the yellow and red GRP markings and take the track which rises towards Plumed Greenhouse. After a steady climb, the path reaches the fork of L'Estouble (alt. 1360m).
2
Continue on the track on a slight uphill slope, direction Plumed Greenhouse. She soon makes a hairpin turn.
3
About 100m further on, watch out to the left for the start of a very small path that climbs quite steeply, still marked in yellow and red. Reach the wooded shoulder of the Serre Plumé mountain. Continue to climb, following the markings carefully (the path is poorly marked on the ground). If in doubt, don't hesitate to reach the top of the ridge; the path is never far away. At times, the route invites you to descend a little by turning left at the bottom of a hole, but this is to better climb back up, always following the ridge line.
4
Finally reach the summit of Plumé Greenhouse (alt. 1573m)This summit offers a magnificent panorama to the east over the Grand Veymont (highest point of the Vercors, 2341m) and over all the high plateaus. Start the descent, always keeping the same direction until the Pass of the Mure (alt. 1435m).
5
Leave the GRP to go right and take the track marked in yellow and green. It runs along the lawns of Darbounouse on the right before joining, after a small climb, the White Hare Lawn (alt. 1455m). Continue on this same track, straight ahead, due north until a fork. Choose to go down towards the Fauchier plain. Pass in front of the Crobache hut, continue on the track until the crossroads of Pré Bellet (alt. 1400m).
6
Prefer the descent to the left to reach the crossroads of L'Estouble then return to the Col de Carri by the path taken on the way there.
