Description of the route

From the Place Moulin dam yard, in the municipality of Bionaz, follow route 10, which runs alongside the lake and reaches the Prarayer refuge. Go past it, then take route 13 on the right at the crossroad, then cross the bridge over the Buthier and continue going left towards Alpe Plan de l’Arp and Alpe Mont-Charvin. Continue up the hillside above the lake ( you come to Alpe Chalet Vieux) until you penetrate the Livournéaz valley, at the start of which you find the lake of the same name.
