From Cervières, take the road leading to Les Fonts de Cervières, passing through the hamlet of Le Bourgea. Park in the car park next to the refuge.
(S/E) From the car park, take the GR®58 heading south towards a footbridge.
(1) Cross the footbridge over the Torrent de Pierre Rouge, then take the path on the left to enter the Pierre Rouge valley through the mountain pastures to the Col du Petit Malrif. Just before the final climb to the pass, the mountain pastures give way to stony ground, which you’ll remain on until the descent to the lakes.
(2) Turn left to climb to the Pic du Malrif along a well-marked path signposted by the GR®58.
(3) At the summit of the Pic de Malrif, continue left towards the north to reach the Col de Malrif.
(4) Leave the GR®58 and carry on straight ahead along the easy path of the Crête aux Eaux Pendantes until you reach the Grand Glaiza.
(5) Turn back along the ridge to return to the Pic du Malrif.
(3) Continue to the left along the ridge path, clearly visible from the summit, heading south to reach Lac du Grand Laus.
(6) Cross the GR®58 path and walk along the southern shore of Lac du Grand Laus. Pass a rocky outcrop to reach Lac Mézan.
(7) Turn right and follow the lake along its northern shore. Cross another rocky outcrop to reach Lac du Petit Laus.
(8) Walk along the eastern shore of this lake and continue along the path heading north, then turn north-east to reach an unnamed pass. At this pass, continue to the right along the easy ridge path leading to the Col du Petit Malrif, which you passed on the way out.
(2) Turn left onto the GR®58 to return to the car park via the same route as on the way out (S/E).
