This walk starts from the car park at the Gresse-en-Vercors ski resort.
(S/E) From the dip in the hairpin bend at the ski resort car park, follow the wide, stony forest track that heads straight ahead.
(1) After a good hundred metres, take the path that veers sharply to the left, heading towards the Crête du Brisou. The path passes beneath the Blavet ski lift and, immediately afterwards, crosses a ski run before climbing a little further into the forest.
(2) At the top of the short slope, follow the path that veers sharply to the right into a wide clearing to reach the summit of the Blavet ski lift.
(3) Continue straight ahead, still heading towards the Crête du Brisou, and enter the woodland on the Crête des Alleyrons.
The path then follows the ridge almost all the way to the summit and, once at the edge of the forest, leaves the ridge itself to follow a very well-marked path to the summit, just below the top station of the Alleyrons ski lift.
(4) The view opens up: the Dévoluy to the east, the Grand Veymont to the west, Mont Aiguille to the south and the Deux Sœurs to the north. You’ll also find two picnic tables.
The return journey follows the same route back to the ski area car park (S/E).
