Markings: Yellow and WhitePR®®, part of theGR®®42.
(S/E) From the car park, near the Laoul Forest House, take the yellow and white marked path heading east, leading to the trailhead and the junction with the La Ligne Forest Road.
Follow it to the left until the next junction.
(1) At the Marchetie signpost, turn left towards the School (former Gras wildlife observation point). Continue along this track. At the next junction: Terres des Moines signpost, continue straight ahead. Reach the La Mourade signpost.
(2) Turn right, follow the track towards Nord Saint-Montan and Bardalène. Ignore the various paths on either side of this track.
(3) At the next junction, by the cistern, follow the track to the right without ever leaving it. Pass under the high-voltage power lines. Continue to the next junction.
(4) Pin de Saint-Montan mast: follow the wide path to the left, heading east towards Bardalène and Saint-Montan. Continue along this well-marked path, which is crossed by countless small tracks that you should ignore.
(5) At the Bardalène mast, descend via a path on the left (sometimes running alongside a track), heading towards Saint-Montan. This path then runs alongside the Bardalène ravine. It becomes winding, cool and damp. It is lined with large scree slopes. It continues to descend towards the Ruisseau de Rimouren.
(6) Further down, you come to a three-way junction. If you wish, you can take a detour down into the stream bed (which is dry) and, after a few steps, see the impressive work of the water on the rocks. Return then to the three-way junction, and continue left along a very pretty mule track, which climbs, forming a balcony path above the superb Rimouren Gorges.
(7) At the first very tight hairpin bend, a small path allows you to make a round trip to a viewpoint to admire the splendid cliffs: Ranc de la Lèdre, Barri Troué.
Continue the climb, heading south. Reach the Pas de l'Yeuse, where the path forms a wide hairpin bend and changes direction: it now heads, through the forest, towards the north-northeast and descends to a road.
(8) At this junction stands the Soulières mast. Take the smallGR®®42road to the right (and the Way of St James marked with a scallop shell). After a few metres, the path climbs to the right alongside vineyards, above a farm. Stay on this path, ignoring the various tracks that cross it.
The path climbs steadily and gradually to the summit of Serre-Court: there are some fine views of Mont Ventoux and the Dentelles de Montmirail. Continue to the next junction.
(9) Reach the Aven des Aubes signpost. Continue left along the Serre-Court forest track, on theGR®®42. * see practical information.
(10) Reach the Laoul-Combe Chambaud mast. There are two options here; the route described avoids the RD4.
At the mast, leave theGR®®42and follow the track to the right, which leads to the Marchetie mast.
(1). Turn left to rejoin the route taken on the way out, leading to the Forest House and the car park (S/E)
and respect the signs along the trail.
