Park in the hamlet of Les Raynauds (Commune of Brette) at the end of the D135a.
(S/E) At the signpost for "Brette Les Raynauds 710 m", take the road towards "Grange Haute - Aucelon - Pennes-le-Sec" (yellow/red markings). At the first crossroads 200 m further on, turn left towards "Die - Crest - Aucelon" (road sign).
(1) After 500 m, leave the road and turn right onto Chemin du Pouget (road sign "no entry except for residents" and yellow/red markings crossed out). This very even path winds its way upwards.
(2) At the fifth bend (on the right), at the junction marked by young, elegant conifers, continue along the path on the right. A little further on, ignore a turn-off on the left.
(3) At the new fork in a bend to the right, continue to the right and you will reach a wide track suitable for vehicles (end of Chemin du Pouget, road sign indicating no entry).
(4) Turn left, following the yellow/red markings ofthe GRP® Tour de la Vallée de la Roanne. Continue along the track, ignoring the paths on the left that lead to the Ravaux farm and its outbuildings. The track climbs steadily, offering increasingly expansive views, particularly of the Trois Becs and Montagne de Couspeau. It then turns sharply eastwards and crosses the valley between Champ Reynier and Bouscarome to reach the pastures.
(5) At the "Bouscarome" signpost, turn right towards "La Servelle". Look out for the yellow/red markings for theGRP® Tour de la Vallée de la Roanne variant and a road sign saying "sens interdit sauf riverains" (no entry except for residents). Go through the cattle grid, which may be open or closed depending on the season.
At the first hairpin bend, take the small path straight ahead (small cairn at the bend) and leave the yellow/red markings to follow the shortcut. The path is not very well marked, so stay in the same southerly direction and rejoin the path higher up at a second hairpin bend.
(6) Then leave the path again to follow the trail opposite (yellow/red marker). Following these markers is not easy in the pastures, but losing them is not a problem as the summit of La Servelle is in sight. Reach it at your leisure, but be careful when approaching the cliffs. Climb over the fence just before the summit.
(7) At the summit, admire the 360° view. Then descend due east, staying on the shoulder to the right of the fence. Pass the Col du Pin. Further on, at the fork in the path marked by cairns, continue straight ahead and to the right, still heading due east (shortcut).
(8) At the "Champ Rabi" signpost, take the track to the left towards "Brette Aucelon".
(9) After about 800 m, you will arrive at the 1944 equipment drop zone (marked by three monumental cairns, one of which has a commemorative plaque) opposite the signpost for "La Blachette": follow the track on the left towards "Bergerie du Serre de l'Église, Brette".
(9) Continue along this track for over a kilometre until you reach the signpost for "Bergerie du Serre de l'Église".
(10) Turn left, still heading towards "Bouscarome, Brette". Pass in front of the sheepfold and continue to the crossroads marked by the "Bouscarome" signpost.
(5) Continue straight ahead towards Brette. From this point, the return to Hameau des Raynauds follows the same route as the ascent.
(4) Be careful not to miss the Chemin du Pouget on the right below the Ravaux farm, as it is less visible when descending. Then follow the outward route to return to the hamlet of Raynauds (S/E).
