A beautiful journey above the valley, departing from the ski lifts of Pelvoux resort.
The demanding trail may seem a bit tough, but the reward is there, with an ever-expanding panorama. The lake, nestled in the hollow of the Rouya summit, gives the end of the hike a more intimate character.
Starting from the top of the Crête chairlift, take the trail that climbs towards Lac de Puy Aillaud following the markers.
