In Gémenos, head towards Parc Saint-Pons. Park in one of the car parks in the park.
(S/E) From the car park, cross the river for the first time. Continue left on the path that runs through Parc Saint-Pons until you reach a path that branches off to the left.
(1) Cross the footbridge on the left, then immediately turn left and walk a few metres until you reach another intersection.
Take the path that climbs steeply to the right into the Vallon du Gour de Brest towards the power line, marked in yellow, until you reach a wide track.
(2) Turn left for a few metres and leave the track on the right to continue the ascent. At the crossroads, at the entrance to the path that branches off to the right, follow the sign saying "ne pas prendre respect de la nature" (do not take, respect nature) and continue left to the Col de Brest. Continue to follow the yellow markings.
(3) At the pass, take the path that branches off to the right along the ridges (not marked on the IGN map). Do not take the path that descends on the other side. Pass the Brèche de la Galère, which you can see on your right, offering a beautiful view. Continue along the overhanging cliff to the Col de l'Espigoulier.
(4) Cross the road, climb a hundred metres and begin the ascent eastwards to the foot of the "Dents de Roque Forcade". Very steep at the end.
(5) Walk along this huge rock face (walls on your right).
Be careful, as the entire section up to the top of the plateau is technical and can be dizzying.
Traces of old blue markings are still visible. Do not attempt the two successive gaps on the right. Go to the end of the cliff, go around it, turn immediately right and use the chains to climb the successive rocks and reach the rocky plateau at the top of the Dents.
(6) From there, the view and panorama are splendid (picnic possible).
(7) Continue on the "Plan des Vaches" plateau towards Pic de Bertagne to reach Col du Cros and then Col de Bertagne. The path is marked with cairns.
(8) At the pass, continue straight on the path that climbs Pic de Bertagne. The ascent is fairly steep but not technically difficult. At the summit, you can turn right to climb the peak to the top. A geodetic network plaque is fixed to one of the rocks.
Retrace your steps, descend to the tarmac road, cross it and take the path opposite which descends to the Col du Fauge.
(9) At the pass, take the path that descends into the valley on the right until you reach an intersection.
(10) Take the path on the left towards Pas de Cugens. Climb the pass using your hands, as it is a tricky passage. At the top, turn and follow the path along the edge of the Cugens cliffs.
(11) Descend and take the path furthest to the right. This path is not very visible but is marked with cairns and runs along the ridge of the Cugens cliff. There is a beautiful view of the entire valley on the right. You will arrive at the GR®.
(12) Take theGR® on the right and continue downhill.
(13) At a large bend to the left, leave theGR® temporarily and take a path that descends to the right to rejoin theGR®. Continue on theGR® to the right.
(14) At an intersection, leave theGR® which continues sharply to the left and take the path that goes to the right towards Saint-Pons Park. You will arrive at the park's waterfall.
(15) Turn left onto the path that runs through the park to the footbridge.
(1) Turn left and head back to the car park (S/E).
