Depart from the D136 road between Pont de Barret and Saoû. Park on the right, just before the tunnel, in the direction of Saoû, after the D128 road junction.
(S/E) Take the path that climbs between the road and the tunnel. Follow it for a few metres, then turn left at the junction on the uphill side. The path passes over the road tunnel through a lawn, then continues on the left at the entrance to the woods. Pass the ridge by turning right and join the road. Follow it uphill to reach the village exit.
(1) Turn right, follow Rue de la Calade, pass under the fortified gate and continue along the paved slanting street that leads to Saint-Marcel Church on its rocky spur.
Go around the church on the right, along the edge of the cliff, and reach the castle ruins. Follow the path that goes around the bottom of the castle and arrive at the main entrance.
(2) Make a round trip to the top of the ridge to enjoy a beautiful view of the ruins and the Roubion valley.
Back at the main entrance to the castle, continue straight ahead along the path that leads to the exit of the old village.
(1) Take the same road you took on the way there, which descends, join the path and return to the tunnel entrance via the same route (S/E).
