After "les Petits Valots", go up the path on your left towards "La Ferme des Velluets" (a farm). Walk around the farm in the direction of the Route de Bourges. Cross the route de Bourges to reach the country path (CR de la Paroisse). Follow this path for about 800 metres, then take the CR on the left in the direction of Miéfou and just before you come to the farm, turn left on to the CR de Mahys.
