From Saint-Bonnet-en-Champsaur, take the D23, then the D123 towards La Motte-en-Champsaur. Drive through the village and take the road to Molines-en-Champsaur; the car park is at an altitude of 1,220 m, reached after 4 km along a narrow road which may be temporarily blocked by flooding from the Torrent des Pins.
Park in the large car park on the right, about 500 m before the entrance to the village.
(S/E) From the car park, turn right, following the sign for “Départ des randonnées” (yellow markings). Walk upstream along the Séveraissette and then the Peyron Roux streams until you reach the village.
(1) Opposite the sign, turn left towards “Cabane de Peyron Roux”. Head back towards the village and take the road on the right just after the ONF lodge. Walk up through the village along the tarmac road, heading north-east. Pass in front of the church and reach the edge of the village, in the forest.
(2) Take the path on the right, still following signs for “Cabane de Peyron Roux” and the “Chemin de Ronde”, for about 100 metres until you reach another junction.
(3) Turn right and cross the Torrent de la Séveraissette via the bridge, heading east. You will then enter the Écrins National Park.
(4) Continue along the path straight ahead, heading south-east, and leave the “Col de Fontfroide – Cabane de Peyron Roux” route on your left. Cross the Torrent de Chagnard, pass through a beech forest, then begin the winding ascent (mostly in open terrain). Enjoy the view of the village of Molines, surrounded by its towering peaks.
(5) Climb straight ahead, heading south-east, still ignoring the path on the left which leads to the Col de Fontfroide. Cross a small waterfall and go round the base of a cliff (short descent). Follow the path along the hillside, sometimes in the open, sometimes under the trees, towards the Cabane de Londonnière.
(6) Carry on straight ahead along the “Chemin de Ronde”, still heading south-east, through a beech forest to reach the Cabane de Londonnière.
(7) Take the path that descends beside the fountain, towards Le Sellon – Le Roy. Ford the Torrent de Londonnière. The path, which then runs along the hillside heading south-east, is sometimes steep, particularly when crossing the Rvin de Ferrière. Cross several small streams before reaching a junction.
(8) Continue straight ahead, heading east, and climb up to the ruined hamlet of Sellon.
(9) Walk through the ruins of the hamlet, leaving the path leading up to the Cabane du Jas de Jartier on your left. Continue along the hillside, heading north-east, cross the Torrent du Colombier, then climb slightly upstream along a path that is poorly marked in places (due to the vegetation).
(10) Cross the Torrent de la Muande, then join the Torrent de l’Espére (or de la Selle).
(11) Turn right to cross the torrent that flows out of a steeply sloping gully. Climb along the hillside in the Vallon du Sellon, heading south-west, to enter the Mélèzin and continue the ascent, which is steep in places. Pass through a steep section, then descend slightly through the forest. Emerge at the boundary of the Écrins National Park and cross the Ruisseau de Riou Beyrou.
(12) Continue along the path straight ahead, heading west, and ignore the path on the left leading up to the Col de la Pisse. Join a track leading to the Route Forestière du Roy.
(13) Turn left to cross the Torrent de Viallet, heading west, ignoring the path on the right which descends towards the Ruines du Roy (a quicker return to Molines is possible by following the track on the right). The path climbs gently and crosses several small streams until it reaches the site of the Cabane de Suzaire. This large clearing is situated at the foot of the Barres de Suzaire cliffs.
(14) After the large boulders, climb slightly and take the path on the right, heading north-west, ignoring the path on the left which climbs towards the Col du Viallet (leading to the Chaillol 1600 ski resort), then, 100 metres further on, the path climbing towards the Col de l’Escalier (leading to Les Infournas Hauts). Continue along the circular path (yellow markings) through the forest, descending gently to the Torrent du Creux de l’Aigue.
(15) Turn right, heading north-west, ignoring the path on the left which climbs to the Col du Cendrié. Descend diagonally through the forest, crossing several streams.
(16) Continue straight ahead on the patrol path, heading north-west, descending until you reach the pebble-strewn bed of the Torrent de la Muande. Be careful: the path becomes less clearly marked as you approach the torrent bed, but the ford is signposted by a signpost.
(17) Ford the torrent, heading north-east, following the few cairns along the way. You’ll reach the Route Forestière du Roy, partly by sight.
(18) Follow the track back up to the village of Molines.
(1) Take the small path on the left, heading in the opposite direction, to reach the car park (S/E).
