From the carpark in La Malène, cross the river Tarn and take the path on the right after the bridge. Take the first footpath on the left (after 300 m) and climb onto the Causse Méjean plateau. Go through Rieisse and, on leaving the hamlet, continue straight ahead towards the Roc des Hourtous. At the panoramic viewpoint of Les Hourtous, walk past the snack bar on its right to take a path that runs parallel to the ridge for 800 m. Then take the path downhill on the left to join up with the path overlooking the Tarn. Turn right onto it to return to the starting-point.
