To reach the starting point from Rochesson, take a small road above the cemetery (C1 Menaurupt 3 km). Drive about 2.5 km along this small road, and as soon as it descends slightly to the left, take the small road on the right and park.
(S/E) Take the small road towards Rochesson (where you arrived) for about 100 m.
(1) Take the track on the left that goes uphill.
(2) When you reach the plateau, take the path on the left: signposted "Ruche des Ducs", marked with a red disc.
(3) Turn diagonally left to reach the small cave called "Trou du Beheu", which is about a hundred metres away. Retrace your steps.
(3) Turn left onto the path that climbs uphill, marked with a red disc.
(4) Stop briefly at the viewpoint to admire the valley and continue to the next junction.
(5) Continue straight ahead, following the red disc markings. Follow these markings to the summit of Roche des Ducs.
Some sections are a little tricky but are secured by handrails.
(6) Passage at the summit where you can stop to admire the valley. Continue along the path, still following the markings. At the first fork, keep left and do the same at the next one.
(7) Leave the path on the right and the red disc markings and take the path that descends to the left, marked with a green ring.
Stay on this path until you reach your vehicle (S/E).
