On the road to La Clusaz, above the hamlet of the Vacherie, take this geological path with fossils which will take you to the slopes of the Lachat.
From the Mont-Jean car park (on the road which leads to the hamlet of Fetelay), take the first path which climbs to the right and passes in front of the Diors farm. Continue on the same track until you reach the Fours chalets. At the crossroads, continue straight on, then passing by the woods, reach the Combe a Banon. The route leads downhill until it reaches the road (Fetelay), which it follows to the left, to get back to the starting point.
