From the Col de Peyresourde, take the D117 towards the ski resort (1,600 m), and park at the start of the ‘Le Privilège’ chairlift.
(S/E) From the car park, take the wide path heading south.
(1) Shortly after the start of the Cabanou ski lift, leave the wide path at a bend to take a small grassy track heading south-west. Then join another wide path below the Plateau ski lift. Continue until you reach the Pène de Magnéras, just past a water reservoir.
(2) Carry on for 100 m and leave the wide path to take a small track at the bend after the Pène de Magnéras. The track heads first south-west, then quickly south-east.
(3) At the 1905 mark, turn left onto theGR®10.
(4) 100 m further on, leave theGR®10by taking the path on the right heading due south along the Ruisseau de Nère. Pass a few rocky ledges – none of which are technically difficult – to reach the first lakes.
(5) Pass between the two smallest of the Lacs de Nère, continuing southwards.
(6) Reach the largest of the Lacs de Nère, and follow a path up its eastern shore without skirting it. The path heads first south-east, then south. It passes beneath the Pic de Nère and turns westwards, towards the Lac des Hermitans.
(7) Walk along the northern shore of this lake, heading west to join a clearly visible but very steep scree path, leading up to a crumbling gully. Cross this gully, clinging to the rocks on the right for easier progress, to reach the start of the ridge path.
(8) Take the ridge path on your left, heading south, using your hands for support until you reach the summit.
(9) From the summit, head back to the small Lacs de Nère via the same route you took on the way up.
(5) Then turn off onto the path on the right, heading towards Couret d’Esquierry. Halfway along, climb down a small rocky outcrop, using your hands for support.
(10) Cross theGR®10without joining it, and take a path heading north-west until you reach the junction at Pène de Magnéras, which you passed on the way out.
(2) Turn right, following the path in the opposite direction to the outward journey, to return to the car park (S/E).
