RANDONNÉE AU LAC DES GRENOUILLES

Take path no. 13 opposite the Hôtel de Vétan-Dessus (a hamlet in the commune of Saint-Pierre), go up a short slope to come out, a little further on, in the middle of the meadows. There, turn right along the ru until you reach the path coming from Tsampiou Alp, which you have to follow until you reach a crossroads below Thoules Alp. By staying well on the left, one climbs towards the alpe Thoulse then towards the ruins of the alpe Grandes Arpilles. From this point and following again a dirt road, you will join the road for the alpe Crottes (which goes to the right) that you will have to follow until the crossing (again on the right) with the path n° 13B that leads to the lake of the Frogs.
