Car park in front of Saint-Georges Church in Désertines.
(S/E) From the car park, walk past the right-hand side of the church and take Rue Christophe Thivrier for 150m; turn left onto Rue du Lavoir and walk down it, then follow a path uphill to the first houses of a housing estate.
(1) Take the first path leading off horizontally to your right, and walk for 500m until you reach a crossroads.
(2) Cross this to join a path opposite which climbs through a chestnut wood, then follows the hillside to a heathland. The path widens as it descends to your right towards the Rocher de la Petite Suisse. Go round it on the right, cross the stream via a footbridge, climb the steps opposite and rejoin the track.
(3) Turn right and follow the road down to a junction of tarmac roads. Turn right and continue to the first road on your left (Rue Henri Martin), which leads straight down to Rue du Lavoir, the road you took on the way out. Then walk to the church where you will find your car (S/E).
