From Ceillac, take the D60. Pass the hamlets of Pied du Mélèzet and Cime du Mélézet, then after 800m, park in the car park on the right-hand side of the road.
(S/E) From the car park, follow the road for about 200 metres until you reach the Queyras cross.
(1) Leave the road and turn left onto the track. Follow it up to the hamlet of La Riaille, pass in front of the Sainte-Marie-Madeleine Chapel, then take the Col Albert path on the right. Follow the markings, staying on the right bank of the torrent.
Follow this path, climbing through the larch trees, to reach a vast plateau with a delightful meadow.
(2) At the cairn and yellow marker, leave the Col Albert trail and turn left to climb northeast into the mountain pasture.
On an intermittent path marked by cairns, climb up the valley, first on the right bank and then on the left bank of the stream. After cutting across a slope of schistose foliates, climb up the grassy terraces and then reach Col Allongé.
(3) Turn right and climb steadily up the Crête du Rissace through grassland and then schist. Reach the summit of Le Longet, marked by a cairn.
(4) Descend the path to the south and then south-west to Col Albert.
(5) Descend to the right into the Vallon de Souchier and then into the Vallon d'Albert.
(2) Follow the same route back to the starting point (S/E).
