Park on the right-hand side of Route de Malval at the start of the descent towards Les Essertines (space for 4 to 5 cars).
(S/E) Walk down the road to the Roulave bus stop on bus 74.
(1) Turn right onto the path that descends into the gorge of the wide and wild Roulave stream, cross the wooden bridge, then follow the gorges without stopping. Join Route de la Côte.
(2) Turn right and cross the bridge. Do not cross straight ahead towards the Côte car park. About 30 metres after the bridge, take the path on the left towards the wild banks of the Allondon (the path is not very visible at first, but it is well marked). Follow it, sometimes through woods, sometimes across meadows, sometimes along the banks, until you reach the footbridge that crosses the fish stream on the right.
(3) Cross the footbridge and, once you have crossed, walk a few metres and then turn left to follow a wide farm track until it makes a sharp right-hand bend uphill.
(4) Just at the start of the bend, take the footbridge on your left, which crosses the fish stream again. Follow the path downhill until you reach the tarmac road at Pont de l'Allondon.
(5) Follow the Mandement road on your right to the crossroads, then turn left onto the Plaine road. Opposite the stadium, cross the car park, then climb steeply to the right of the vineyard to the aptly named Chemin de la Corniche.
(6) Turn left and follow Chemin de la Corniche through the vineyards until you reach a public bench overlooking La Plaine station and the Firmenisch-DMS perfume factory.
(7) At the bench, turn right and climb the steep concrete vineyard maintenance road until you reach a bicycle shelter decorated with a fox. Then follow the route along the tarmac farm roads to the Dardagny inn.
(8) Shortly before the inn, take Chemin de Bertollier on the left and then, at the bend, take the path on the right. Continue along the staggered route until you reach a large span between the vineyards on your right.
(9) Take the crossing on your right and, at the exit, turn left onto the Malval road to quickly reach the starting point (S/E), at the bus stop or your car.
