In Cervières, take the Fonds de Cervières road. Park in the car park located after the Mur des Aittes and before the hamlet of La Chau.
(S/E) At the end of the car park, take the wide, well-maintained path that climbs north-west. Stay on this path until you reach the perpendicular track connecting Cervières to Lac Noir.
(1) Leave this track and continue straight ahead to reach Lac des Sarailles after a short climb. Walk along the left side of the lake and stay on the path to reach the Cabane de Douaniers.
(2) Make a round trip to Lac de Peatland Enfonza.
(2) Back at the hut junction, turn left onto the almost horizontal path that leads to a small lake in a valley near Lac du Rouséou.
(3) Continue straight ahead, taking the well-marked shortcut up the slope. You will then rejoin the level path, which further on leads to a Y-junction.
(4) Keep left and follow a final, very short climb to reach Lac Gignoux.
(5) Return to the previous crossroads.
(4) Take the wide path downhill to the left and walk through the mountain pasture to find the crossroads leading to Lac Noir.
(6) Turn right to quickly reach Lac Noir via a round trip.
(6) On your return, take the path that descends southwards, following a few hairpin bends, to reach the hamlet of Les Fraches.
(7) Walk past the ruined chalets to reach the hamlet of La Chau.
(8) Here, turn right onto the wide track that leads to the road. Turn right onto this road to quickly return to the car park (S/E).
