The starting point is at L'Oustal sur le Caussanel, a central public space with easy parking.
Follow the yellow signs throughout the route.
(S/E) Go up and take the no-entry road on the left of the lake. You will soon come across the first signpost on the discovery trail (Puits Caselle). At the crossroads, turn left and then immediately right. Continue on your way, making sure you keep heading north.
(1) At the stone cross in Le Sullé, leave the road and turn left onto the path.
(2) Leave the yellow signs to see the landmark 50 metres away (lake), then retrace your steps and follow the yellow signs again. Follow the road, then take the path between two dry stone walls.
(3) Turn left at the Cayrou information board and continue south. Ignore two paths on the left further on and reach a road.
(4) Cross carefully and continue straight ahead towards Mas de Cormès, pass it and arrive at the main road that crosses Espédaillac (D40).
