After the hamlet of Mont Piton, head towards Les Cheneviers and park in the car park at the end of the road.
(S/E) From the car park, follow signs for “Sous-Dîne”, “Col de l’Enclave” and “Passage du Monthieu”.
Continue left along the forest track, which climbs fairly steeply to the junction of the circular route (alt. 1,390 m).
(1) Ignore the return route ahead (Col de l'Enclave) and turn left towards "Sous-Dine via the Passage du Monthieu". The forest road offers a gentler climb up to the Combe d'Arembeau.
(2) Keep to your right towards Sous-Dine. The fairly wide path at the start of the valley narrows after the right-hand bend.
(3) Pass another path on your left coming from Mont Piton. Continue to the right (south). Two sections with ropes (not too difficult on this side of the climb) lead to the Passage du Monthieu.
(4) The route then continues to the plateau, skirting the cliffs where the view is certainly magnificent but where there is a risk. You’ll reach a fork.
(5) There are still 100 m to go before you reach the cross marking the highest point of Sous-Dîne. Enjoy the view of the cliffs, the Aravis and Mont Blanc massifs, and the chamois.
(6) Return to the previous fork.
(5) Turn left, south-west, for the descent via the Col de l'Enclave. The descent is interesting through the lappiaz formed by the erosion of limestone. You will reach a crossroads (alt. 1,770 m).
(7) Keep to the right to reach, through the forest, the Route des Cheneviers before the Col de l'Enclave.
(8) Leave the mountain road on your right and take the path on the left leading to the Chalet de l'Artu and the Col de l'Enclave (alt. 1495 m).
(9) Follow the path to the right, heading due north, which rejoins the mountain road you left earlier. Continue left along this road and return to the original junction.
(1) Follow the path in the opposite direction to the outward journey to reach the car park (S/E).
