Park in the designated spaces on the D23. There is room for several vehicles.
(S/E) The trail starts between a wooden sign marked Sainte-Eulalie and a cairn. Head north, following the yellow markings. You will soon reach and cross the railway line. Continue straight ahead on the trail to reach a crossroads.
(1) Turn right (note: the wooden sign is broken). Continue north, cross the hamlet of Les Caussonels and reach the water source at Cernon.
(2) Cross the stream and take the path on the left. Cross the Cernon and continue straight ahead until you reach a crossroads with a cross.
(3) Turn left onto the wide path, then immediately right onto the trail. Reach the antenna and turn left onto Rue Puech de la Vigne. Turn left onto Rue de la Roche, then right onto Rue du Moulin and finally left onto Rue Le Pont (D561). Follow this street to the trail junction.
(4) Take the path on the left and follow the yellow markings, which will allow you to avoid taking the D561 for part of the way. Join this road further on and follow it to the next hairpin bend.
(5) At the circular, turn left onto the path, which is still marked with yellow signs. Cross the rail bike path and continue slightly uphill to reach the highest point (795 m), which is a crossroads of paths.
(6) Turn left onto the small path marked with a wooden sign: Saploum. Caution: it descends steeply and is quite rocky.
Further down, join the railway line and take the tunnel that passes underneath.
Note: if you are afraid of the dark or do not have a torch, you can go around it on the right.
Continue to the first crossroads.
(1) Turn right and follow the same route you took on the way there to easily reach the car park (S/E).
