The route starts at the car park at the Roche du Prêtre viewpoint.
(S/E) From the car park, take the inconspicuous path that branches off to the right, running alongside the fence and skirting the drop. There are numerous panoramic views along this section of the circular route. Be careful, however, as the drop-off is impressive. Continue straight on until you reach the statue of the Virgin Mary, crossing several paths and tracks—some more clearly marked than others—and following the green markings. At the statue, continue to another viewpoint overlooking the cirque.
(1) Continue along the path and descend to the left, down a steep, winding slope. Cross the first track, then at the second, turn left onto a very muddy path. Pass a junction to reach a second one near the Source Noire.
(2) Follow the path down to the right. Soon, a viewing platform offers a view of the spring. Descend to a wide path.
(3) Follow it to the right to cross the river. Continue along the other bank to reach the religious buildings.
(4) Turn left and head up the road. Continue straight on to the bridge. Then follow the steep path on the right to reach the town hall, the restaurant and the zip-line reception. Go up between the restaurant and the reception, then continue straight on to reach the Source du Dessoubre.
(5) Head back down and follow the path to the left, before the restaurant. After a few metres, turn left onto the path, round the bend in the road and follow the path to the left towards the Belvédère de Ste-Catherine. You’ll soon reach a fork: continue left onto a path, which is sometimes narrow and vertiginous. After a steep descent, cross an open area and go straight on to the belvédère.
(6) Enjoy the view of the cirque. Return to the junction and head down to the left, towards the river. After a bend, reach a stream and follow it down to a footbridge.
(7) Head right towards the Grande Cascade. This can be seen on the right. Another waterfall can be reached at the very back of the cirque.
(8) Take in the scenery and return to the footbridge via the same route.
(7) Continue straight on to the next junction.
(3) Turn right and cross a stream before beginning the climb. At the track, follow it to the right until it ends. From here, a technical path begins with dizzying steps that allow you to gain altitude quickly. Reach a junction at the top of these steps.
(9) Turn right onto a path that is sometimes quite narrow and runs regularly along the cliff face. You will reach a cave at the Source du Lançot.
(10) Continue and, after a bend, climb some more steps to reach a wide track. Follow this track to the junction at La Scie-dessus.
(11) Take the first path which climbs steeply to the left. Halfway up, veer slightly to the right, then left at the end of this section to reach the Roche du Prêtre viewpoint.
(12) Enjoy this final view of the cirque and continue walking to the car park. (S/E)
