To get to the starting point, after Tarascon, take the D8, turn right towards Vicdessos, then Auzat, Marc and finally Étang de Soulcem. Park your car below the dam, just at the start of the Lacs du Picot trail on the left.
(S) The trail, which is flat at first, turns south-east and climbs in very steep switchbacks along the Picot stream on the left. Take a short break, which is necessary after this very strenuous climb, to admire the Picot orris. Then continue the climb to a first small pond and continue on to reach the first Étang du Picot.
(1) Continue on to the second pond, in a magnificent setting dominated by the Pic de Malcaras slightly to your right.
(2) Leave a path on the left and begin the steep climb to the last Étang du Picot, which is just as beautiful as the previous one.
(3) Once at the edge of the lake, follow the path which climbs steadily at first, then turns 90° to the left and becomes very steep (breaks are necessary, especially with a heavy rucksack) to reach a pass at 2645m.
(4) Descend into a small stony valley, taking care when crossing any remaining snowfields, and then climb back up to a second pass.
(5) Begin the descent towards the small Étang Fourcat lake straight ahead, then the second Étang Fourcat lake on the right, dominated by the Pic de Tristagne, which closes off the mountain cirque.
At the junction with the path on the left, which comes from the Etang d'Izourt and passes through the Orri de la Caudière, turn right and continue south. The Refuge du Fourcat is easily spotted on the rocky outcrop that separates the two lakes.
(6) Turn left towards it and take a well-deserved break after all your hard work. Enjoy the view of the large Étang Fourcat.
Below the refuge, find the path that leads to the shore of the lake, then turn north-east to follow it as closely as possible.
(7) Pass a rocky outcrop and follow the cairned path that leads to Étang de la Goueille, where you can camp for the night in a wild and magnificent setting (E).
