From the Cluses Tourist Office (21 Grande Rue), you’ll need to drive to the village of Saint-Sigismond (a 15- to 20-minute drive).
From the A40 Geneva-Chamonix highway:
Take exit 19, then follow signs for Cluses – downtown.
From the center of Les Carroz, drive back down to the village of Arâches, then turn right after the church toward La Frasse and Saint-Sigismond.
Once you arrive in Saint-Sigismond, take the road that goes up to the right toward Agy.
