Starting from St Hugues in Chartreuse (parking near the church), head towards Flin. Stay on the path that crosses the meadows, and from Flin, head towards Vivier. Continue on to Cherlieu, and at the edge of the hamlet, climb into the Coleau woods towards Le Clot. From there, reach Les Epallets and then the Crêt des Egaux, and return to St Hugues via the Old Road of Cherlieu.
