Access
In the Grésivaudan valley, go to the Col du Barioz (south of Saint Pierre D'Allevard) and take the D281B to the cross-country ski centre (car park).
(S/E) From the car park at the Barrioz cross-country ski centre, walk back down a few metres and take the path on the right (north). This path winds gently through the forest. One of the bends can be cut by taking the GR®.
(1) Follow theGR® to the Refuge du Crêt du Poulet.
(2). At the refuge, you can continue to the summit of Crêt du Poulet.
(3) Retrace your steps.
(2) Continue south on the path and cross another path. Then, take the first fork to the right and the second to the left.
(4) In a small copse, take the path veering slightly to the left (GRP® yellow and red markings). The path rejoins the trail a little further on at a small lake (which may be completely covered by vegetation).
(5) Just after the lake, at the top of a small hill, stay onthe GRP®: the trail branches off to the left of the path but is not very visible. The trail rejoins the path at a second lake. At Crêt Luisard, go around the lake on the right.
(6) At the hill, leave theGR® for a small path on the right that descends and leads to the Chalet de Pierre Roubet (note that the start of the path is not clearly visible).
(7) During the descent, at the fork, take the path that branches off to the left. At the edge of the forest, you will come to a forest track which you should take to the left towards the Chalet de Pierre Roubet.
(8) Continue to return to the Foyer de fond du Barioz (S/E).
