Park in the car park situated below, to the left of the track (the D128 leading up from Genèbre), about 1 km before the Ossoue Dam.
(S/E) Head up the track, north-north-west. Cross the Ruisseau de Labassa and reach the Ossoue Dam.
(1) At the foot of the dam, turn left and take the footbridge to cross the Gave d’Ossoue. Then follow the GR®10 southwards (red and white markings). The path initially climbs steeply up the hillside. It then continues along a gentler slope until it reaches a wide hanging valley.
Continue southwards, passing the Cabane de Lourdes on your right by a few metres, until you reach a junction of signposted paths.
(2) Walk past the signpost and take the summer pasture path towards the Col de la Bernatoire. (South-west; let the GR®10 branch off to the left). The path climbs gently up the Canau valley, then turns left (south).
As you approach the pass, the gradient steepens. After a steeper climb for a few metres, you’ll reach the Col de la Bernatoire.
(3) From the pass, turn immediately 90° to the right and climb steeply up the narrow track. The slope levels out quickly and the going becomes easier. Follow this path to reach the summit.
(4) For the return journey, follow the same route in the opposite direction back to your starting point (S/E).
