Start at the bottom of the Jarjatte ski lift (car park).
(S/E) Head south-east on the GR®94 to the bend in the road.
(1) Leave the GR® and take the marked path on the left. The path crosses the ski lift line and then climbs into the Champ Tondu woods.
After the summit (elevation 1413), ignore the two paths on the right that descend towards the ski slopes, then take the path that climbs uphill.
(2) From there, the trail continues almost horizontally through the forest. You will soon reach the permafrost of Combe Obscure.
(3) After a few clearings in the forest offering beautiful views of Tête de Lauzon, the trail opens onto the vast cirque of the Mougious meadows. On the left below the path, you can see the Mougious Fountain.
(4) At the entrance to the forest, do not take the path on the left that descends into the Ravin de la Chaumette. Continue straight ahead on the forest track that leads to the edge of the Buëch, then follow it to the left.
(5) At the crossroads, take the path on the right which leads directly to the stream. There used to be a bridge here, but it was washed away and will probably not be rebuilt. When the water level is low, it is easy to cross, but it must be impossible when the flow is strong. In this case, you can always turn back a few metres to the crossroads and take the path on the right that leads back to La Jarjatte via the left bank of the Buëch.
(6) After crossing, turn right and then immediately left onto a path that leads to the Cabane du Fleyard (and, beyond that, to Lac de Lauzon). This path then joins the forest road, which you take to the left. After a double bend, you will come to a signpost in the Ravin du Lauzon.
(7) From there, you can make a short round trip to the hut, which is a pleasant spot, then retrace your steps and take the track that climbs left into the woods above the road. In this section, there are several tracks and not many markers, but as soon as you leave the woods, you will see the path clearly marked out in the pastures. The path continues horizontally across the pastures, then begins to descend, passing by a livestock farm and, after crossing a wood, joins the GRP® Tour du Devoluy, which descends from the Col de la Croix.
(8) Follow the GRP® to the left until you reach the D505, which takes you straight back to the start, ignoring all turnings to the left and right (S/E)
