Park in the car park of the Auberge de la Croix de Messire Jean, which is also the starting point for the hike by joining the path at the end of the car park.
(S/E) Take this fairly wide path to the right and follow it. You'll pass the first pond. Continue along the same path, ignoring the intersecting footpaths.
(1) You've now reached Étang Neuf. Keep following the same path, which leads away from the pond and comes to a crossroads with a small road. Turn right and follow this road to a track on the left.
(2) Take this and turn right further on.
(3) You'll pass between the Etangs du Prieuré. At the end of this path, turn right, then right again at the fork. At the next crossroads, take the left-hand path and continue to the next crossroads.
Fork right, then left at the next junction. Further on, at another junction, turn right. Further on, cross a wider path, so continue straight on.
(5) You'll come to Étang Taupin, where you'll see a tree that has grown under rather difficult conditions. Continue on the same path to reach a wider road and the D275, which you cross. Follow this road to a crossroads near the Étang des Ravelottes.
(6) Turn left onto the track which becomes a footpath. After a short walk, you'll reach "La Pierre qui croule" ('The crumbling stone').
(7) After a pause and perhaps trying to move this 24-ton stone, continue on the same path, which will descend a little further than you have done so far, reaching a wider track at the end of the path. Turn right and follow this path, ignoring the intersecting trails.
(8) After a moment's walk, turn off the path on your left to see "La Griffe du Diable" (The Devil's Claw). Return to the path and continue straight ahead, soon a house on your left, then continue on the path heading to the right, which will later become a road.
(9) On your left, there's a car park, go in this direction to see the "Rochers du Carnaval" ('Carnaval rocks'), spend a little time there then return to the road you're following to reach the D275 again. Turn left and return to the hostel car park lot and your starting point (S/E).
