Park on the left, before a right-hand bend, next to a scrap metal enclosure, before crossing the Ruisseau du Brouilh stream. This car park is located at the end (of the drivable section) of the Route Forestière de l'Aya.
(S/E) Continue a few metres along the road (altitude 1307). Turn left just after crossing the Ruisseau du Brouilh. Note: the purple route on the IGN map is incorrect.
Follow the yellow markings towards Lac de Peyrelade. Climb up along the left bank of the stream. Leave the first track on your right. Pass the altitude 1326.
(1) At the fork (1345 m), take the wide, grassy track on the far right. Follow the old yellow markings. Ignore the adjacent paths and tracks. Continue climbing along this wide grassy track, which becomes cluttered with fallen trees that litter the original marked path.
(2) At the crossroads of tracks and paths (1500 m), turn left.
Caution: This is an open area. There are many possible routes. It is essential to look for the old yellow markings and cairns to continue.
Continue climbing up a narrower, grassy track. Continue climbing, following the yellow markings and cairns. The track then becomes stony. Continue climbing, looking for the old yellow markings and cairns.
Note: the representation of tracks and paths on the IGN map is not up to date.
(3) At the fork, leave the track and turn right onto a path that climbs steeply through the forest. Continue along this well-marked path. Follow the old yellow markings and you will come out of the forest. Now you have a clear view (1700 m). Pass a wet area and turn left onto a beautiful grassy path that winds its way up to a ridge. Note: the route on the IGN map is incorrect. Simply follow the yellow markings, which are in better condition in the summer pasture area.
(4) At the ruins of the Cabane de Lahus (1780 m), enjoy the beautiful panorama before you: Montaigu, Montée au Lac Bleu, Cabane de la Lit, Hautacam.
From this summer pasture area (Clot dets Touts), continue due east, climbing up a well-marked path with yellow markings. Look for the sign on a rock: Peyrelade.
Caution: Do not follow the marked trail, which is reserved for experienced hikers.
Pass the altitudes of 1820 m and 1891 m. Be careful at the start of the season as there are still some snowfields in this scree area. Continue climbing along this path which winds through the summer pasture.
(5) At the fork (1960 m), leave the yellow markings. Turn left, heading due east, onto a path that is very well marked on the ground. Then turn left again and follow a ridge path that heads north towards the summit.
(6) At Cap de Labasset (2,038 m), enjoy the 360° panoramic view. A well-deserved break may be considered. Descend via the same ridge path towards the lake. Return to the previous fork.
(5) Climb slightly to the left to find a good yellow mark. Follow this route carefully so as not to further erode the path and reach Lac de Peyrelade.
(7) Take advantage of the beautiful surroundings of Lake Peyrelade (1,919 m) to rest. Now it's time to think about the return journey.
Follow the yellow markings, staying on the right bank of the stream. Now simply follow the path, which is very well marked and signposted in yellow. Pass through wetlands and small streams. Be careful as the path is very uneven in places. Return to the initial crossroads.
(1) Fork in the path. Take the right fork, in the opposite direction to the outward journey. Head towards the car park, staying on the left bank of the Ruisseau de Brouilh. Return to the car park where you started (S/E).
