Access: from Saint-Vincent-sur-Jabron, take the D303 (towards Châteauneuf Miravail), cross the bridge and park on the right at the wooden signpost marking the start of the hike. The parking area on the side of the road is quite small (maximum 3-4 vehicles).
(S/E) From the bridge, take the small tarmac road on the left, following theGR®946(red/white markings), which is shared with theGR® de Pays de la Grande Traversée des Préalpes (yellow/red markings).
(1) At the first hairpin bend, leave the tarmac road and continue straight ahead on the path that climbs up following theGR®946(red/white markings).
After 120m, the path rejoins the small tarmac road. Continue along this road for about 400m, staying on theGR®946and ignoring a turn-off to the right.
(2) At the entrance to the small hamlet of Fréméson, leave the tarmac road and take the track on the right, continuing on theGR®946. You will come to a track suitable for vehicles.
(3) After about 450-500 metres, continue straight ahead on theGR®946, ignoring the turn-off to the right. Stay on the track suitable for vehicles.
(4) After about 300 metres, continue on theGR®946to the left, staying on the track. Ignore the faint path on the right.
(5) At the next intersection, continue on theGR®946to the right, staying on the track. Ignore the turn-off to the left.
(6) After 250 metres, continue straight ahead on theGR®946, staying on the same track.
After 100 metres, ignore the faint turn-off to the right.
(7) After travelling approximately 1.3km on the track, at the intersection, continue on theGR®946to the right. Leave the track for a narrow path that climbs more steeply.
(8) At the fork marked by a tree in a small clearing, continue left towards "Pas de la Graille" (GR®946- red/white markings).
The track then winds its way near the north-facing slope and cliffs of Montagne de Lure. You will cross four marl deposits (with scree and numerous rocks).
(9) At the fork, continue on theGR®946to the left via the small path. Ignore the start on the right on the wide track.
You will arrive at the "Courboures" sign.
(10) Continue straight ahead on theGR®946.
(11) At the junction of several tracks coming in from the right, continue straight ahead on theGR®946, taking a wide forest track that is slightly uphill. Continue for about 2km until you reach the access barrier and the junction of two wide tracks suitable for vehicles.
(12) Continue on theGR®6towards "Pas de la Graille" by taking the forest track on the right for 200 metres.
Then leave the forest track and continue on theGR®6to the right. The track becomes narrower and steeper.
The D53 departmental road will be crossed three times. Continue on theGR®6, following the track which runs almost straight ahead. Below Pas de la Graille, the slope becomes much steeper.
(13) At Pas de la Graille, turn right towards "Crête de Lure" and "Sommet de Lure" on theGR®6.
Then start walking along the ridges of the Montagne de Lure in an east-west direction and arrive at the Crête de Lure.
(14) Continue right towards Sommet de Lure on theGR®6.
(15) At the Sommet de Lure, continue towards "Les Relais" and "Station de Lure" on theGR®6. When you reach "Les Relais", continue west along the ridges towards "Station de Lure" and "Ponchon du Roux" on theGR®6.
(16) After walking about 1 km from Les Relais, continue along the ridges to the west and leave theGR®6at an altitude of 1,716 m towards Les Barres.
(17) At "Barres", follow "Crête des Cavalets" and "Pré du Fau", marked in yellow.
(18) At "Crête des Cavalets", continue westwards, staying on the ridges. The path is marked by a cairn. Leave the yellow markings. Reach the "Sommet de l'Homme" marked by a large cairn.
(19) Continue along the ridges as you descend. A few cairns mark the trail. The trail then passes along the edge of the forest with a steeper slope. At the bottom of the slope, pass close to the ruins of a jas (sheepfold) on the right.
(20) At "Baisse de Malcort", take the path on the right that descends into the forest. Continue along the relatively wide main track for 2.5km, ignoring the paths on the right and left.
(21) At the crossroads of several wide tracks (near the Parandière sheepfold), take the track on the left.
(22) After 400 metres, leave the track and take the path on the right. Yellow markings.
(23) After about 500m, continue straight ahead, following the yellow markings. The path climbs, then runs alongside a canyon above the Pissais river.
(24) After 1.5km, continue left on the main track (yellow markings). The path straight ahead is not very clear. The track then widens until it becomes a road.
(25) At the edge of a meadow, continue left on the track suitable for vehicles.
(26) After 600 metres, at the fork, continue right on the track suitable for vehicles. Stay on this track and continue for about 1 kilometre to reach the D303.
(27) Turn right, following the yellow markings, onto the downhill road.
(28) After the hamlet of Les Costeliers, ignore the turn-off to the left with the yellow markings. Continue along the road until you reach the bridge at the start (S/E).
