(S/E) From the Ducs car park, follow the path leading to the climbing site in a north-easterly direction.
(1) From the climbing site, cross the small ford over the Combe d'Oyans stream and continue north-northeast. Keep going in this direction. Ignore the various paths branching off to either side of the main path.
The rest of the route is partially marked in yellow and white.
After a small pass, you will reach a junction with aPR® marked in yellow and white.
(2) Turn right at a right angle onto the narrower path heading east and join the path coming from Beauregard-Baret.
(3) At the Saint-Isérat signpost, turn right (southeast) towards the Col de Sonnaize.
(4) At the Col de Sonnaize (hunters' shelter), continue in the same direction to the Pas du Loup.
(5) Shortly after Pas du Loup, on the left, there is a small, very steep path leading to the Ussets cave and back.
(6) Grotte des Ussets: the site is quite pretty. Do not venture too far inside the cave without the proper equipment: it is a real tunnel and not just a hole. Turn back.
(5) Continue to the left (south) and you will immediately reach the Pas du Loup (a very pretty viewpoint a few metres to the right).
(7) The path descends for a few steps: be careful not to miss the junction and turn left (east) towards Montagne des Ussets and then Col de Tournier.
(8) Reach the pass and a three-way junction. Take the middle path, which climbs slightly, towards Source de Font Pourcel. Stay on this path, heading south-east, ignoring the paths that cross it until you reach a wide track.
(9) Follow this track to the right, descending towards Les Pignes. Pass close to the Source de Font Pourcel.
(10) Shortly before reaching a crossroads, take a path slightly uphill on the left and head south towards Verdu. Stay on level ground and pass above the poplar trees, continuing to a fork in the road (directional mast).
(11) Turn left towards Pas de Bouvaret. The path climbs quite steeply to reach the Sentier de Bouvaret.
(12) At the next fork (Courbières signpost, 880 m), descend to the right towards Grimeaud (2.1 km). Stay on the path, ignoring any paths that cross it, and descend to a small road a little further down.
(13) At the road, continue climbing to the left. Pass a farm and a golden retriever breeding facility. A wide track follows the road. A few metres further up, at a crossroads, turn left. Continue climbing. Pass a path on the left before reaching a small pass and directional masts. Follow the path to the left towards the north-west, Totet, Coquat North and South. Stay on the marked path, ignoring any paths that join or cross it.
(14) At the next crossroads (Coquat South signpost), continue straight ahead, heading north towards Coquat North and the castle ruins.
(15) Rochefort-Samson Castle mast: make a round trip to the castle ruins (information board).
Return to the mast and take the path on the left leading to the Rochefort-Samson road. Follow the road to the left.
(16) At the next junction, descend via a path to the road. Follow it straight ahead to the Ducs car park (S/E).
