Direction of travel: clockwise Landmarks and connections: Sévrier (turn off with the Circuit de Leschaux n°8); Col de Leschaux; Gruffy (turn off with the Circuit de l'Albanais n°11 and Annecy-Aix les Bains n°51). Description: Apart from the road that runs along the Vallée du Chéran, (the only way out of the mountains), Coeur des Bauges is defended on all sides by high ridges, of which Leschaux is the lowest. 12km long with 480m of elevation change (with an average incline of 4%) and an even profile, it is the most popular route for cycling in the Haute Savoie and is perfect for beginners. To reach the foot of the mountain (RD912), leave the Voie Verte at the Port de Sévrier and follow the departmental road n°1508 for 1.5km towards Annecy, which you will reach after making a delicate left turn. Once you cross the ridge and reach the Vallée du Chéran (RD911), look out for a right turn onto the Route d'Allèves, which will take you to Annecy. But beforehand, we recommend that you make the 2km round trip to see the impressive Abîme bridge, it's worth it!
