Park in the Place de l'Église car park in Rougemont-le-Château.
The walk is marked with a red ring.
(S/E) Follow the street opposite the car park, cross Rue de Masevaux (D2a) after the war memorial, and take Rue de la Bavière.
(1) The street splits in two; take the left fork. After 400 metres, it becomes a footpath.
(2) After a fairly steep climb, at a place called La Coiche, it joins the GR®532 marked with a yellow rectangle. Take it to the right. 100m further on, you will come out at Le Plainot. A sign indicates that you are entering the Natura 2000 area.
(3) Take the forest path on the far left. The path makes a sharp left turn and follows the Sainte-Catherine stream. Walk along the quarry on your left. Cross the stream.
(4) At the bottom of the quarry, a few metres before reaching the D51, turn right onto a small path that runs alongside the departmental road and then veers away slightly to run parallel to it.
(5) Turn right onto the D51. Admire the Christ on the cross. A little further on, look for the cross in the middle of the pasture on the right.
(6) 500 metres further on, cross the Saint-Nicolas to the left, making a hairpin turn towards Etueffont. Climb for 200 metres, then descend to the left via a path overlooking the right bank of the Saint-Nicolas. Cross a stream, leaving a forest path on your right.
(7) About 800 metres further on, the path joins a tarmac road. Follow it to the left for 300 metres to reach the D51. Walk slightly uphill to the left for 100 metres.
(8) Take the path on the right, then immediately turn right onto the path that climbs uphill. About 100 metres further on, cross the path, turning right and then immediately left. Pay close attention to the markings on this section as the path crosses tracks and plot boundaries.
(9) Cross the stream and turn left immediately afterwards. The markings are helpful. Cross two forest paths and, after a right-hand bend, descend along the stream below. Pass between two fences at the edge of the property, go down the stairs and arrive in the town of Rougemont-le-Château.
Take the street on the left and rejoin the starting point at the bottom of Rue de la Bavière. Walk past the town hall on your right and arrive at the starting car park (S/E).
