South of Carcès, on the D562, turn left onto a small road, the Chemin des Riaux (red signs). Ignore a small road on the left, then another on the right, and continue towards Les Riaux for just over 1 km to reach a car park at the junction of several paths (the Visorando app can also help you find the starting point).
(S/E) At the car park, turn immediately right onto the Serre Long forest track, which climbs steeply westwards then north-westwards and passes under a power line.
(1) Turn left onto the tarmac road, which is also theGR® 653A (one of the Camino de Santiago routes). At the water tower, continue straight ahead, then leave the road to follow the forest track from the water tower.
(2) After the CCS5 fire tank, turn left onto the track that climbs. Then, shortly afterwards, turn left again, leave theGR® and follow the Chapelle Saint-Vincent forest track (it climbs very steeply) to the junction with the path to the chapel.
(3) Turn left to visit the chapel and the viewpoints, as well as the remains of the oppidum. Retrace your steps.
(3) Continue along the track to the left, which stays on the ridge with views on both sides. Pass under the high-voltage power line twice. Take care on the steep descent along the very stony path. Pass a path on your right.
(4) Turn right, passing the CCS4 fire tank (which is on the left). Continue along the forest track which will take you back to the car park (S/E).
