The starting point is a car park located just after the Saint-Claude exit (RD69 road).
(S/E) Cross the road carefully and take a path.
(1) At a fork, continue left along the path.
(2) After about 250 metres, take a path on the right: the slope is quite steep at first, but then becomes much gentler. You will come to a path which you follow to the left downhill.
(3) Not far away, you will come to a three-way junction: continue right towards Vaucluse.
(4) Turn right towards Rocher du Frênois and the Crêt Pourri viewpoint and follow a path with a few steep slopes for a short while. Near a power line, join the ridge line overlooking the start of the Rocher du Frênois cliff.
(5) Continue left along the path following the cliff line and after a short while you will reach a ruined house (named Rocher du Frênois according to the signpost): continue right along the path leading to the viewpoint (located about 300 metres away).
(6) Enjoy the view of the surrounding area. An orientation table is available. Retrace your steps back to the ruined house and turn right towards Le Frénois. After a climb and then a descent, you will reach a small road
(7). Follow it to the left for about 100 metres, then take thesecond path on the left downhill. Stay on this forest path for about 500 metres: turn right, following the yellow markings, to take a path with an uphill slope.
At an intersection, turn left (note that the markings are not clearly visible in this direction at this point) and follow a gently sloping path for a short while. You will come to a road.
(8) Follow it to the left for about 700 m, following the yellow markings. At a bend in the road to the right with a slight upward slope, continue straight ahead following the path (follow the yellow markings): this then runs along the edge of the plateau on a rather pleasant route. After a short descent, you will come to a junction and join theGRP® Tour de la Haute Bienne.
(9) Continue left on thisGRP®, then turn left onto the yellow-red marked trail. The path then continues with a few steep slopes. At the intersection with a tarmac road, turn right until you reach the hamlet of Vaucluse
(10) At the chapel, turn left towards Saint-Claude (yellow-redGRP® sign).
(4) After a short while, you will reach a fork that you already saw on the way there. Continue straight ahead.
(3) At the Très Bayard crossroads, either turn left and retrace your steps from the outward journey, or continue straight ahead (the route indicates the second option).
(1) Follow the path on the right and return to the starting point (S/E).
