Park opposite the Fontcouverte campsite. If the car park is full, there is another one 200 m further on.
(S) Immediately join theGR®57trail, which heads off to the left. Begin a fairly steep climb, passing in front of the Laraux chalets. Stay on the path to the right, continuing on to cross the stream via a small wooden bridge. Continue the ascent to reach the Refuge du Chardonnet.
(1) Continue through the mountain pastures, still on theGR®, and, after crossing the Ruisseau du Raisin, reach the junction with theGR®57.
(2) Take the right-hand branch towards the Col du Chardonnet; the left-hand branch leads to the Col de Terre Noire. Continue the ascent, skirting the dry bed of Lac du Châtelard. Begin the final climb, passing some distance from Lac de la Mine to emerge at the Col du Chardonnet Sud.
(3) Here, begin a fairly steep descent with numerous hairpin bends. Finish this descent at the junction at the hamlet of Clôt des Vaches.
(4) Keep to the right on theGR® and begin another gentle climb. After a wide circular loop to the left, reach the junction with the Grand Lac trail, near the shepherd’s hut.
(5) Turn right and continue the climb through the mountain pasture to reach, without difficulty, Lac de la Ponsonnière, today’s stop and campsite (E).
