This itinerary takes you up to the chapel and ruins of the castle of the Sires du Faucigny at Châtillon sur Cluses, and guides you along the farm tracks of Mieussy.
After the Gorges du Pont du Diable, you can follow a Roman road to reach Chapelle Saint Grat. The banks of the Lac de Flérier offer you the chance to cool off and relax. A route that's sure to make you appreciate your bike's electric assistance, especially on the climb after Bois Dessous or at Chosalet. Two descents to keep an eye on: Vers Sache and l'Étroit Denté.
