From Vallouise, take the D994E towards Ailefroide and then on to Pré de Madame Carle. Park in the car park near the mountain refuge. The car park entry fee is €2.
(Out and back) From the Madame Carle Refuge, take the path to the north-west towards the glaciers.
This path crosses the Momie torrent and the Glacier Noir torrent, then winds its way uphill.
(1) At the third hairpin bend and the signpost (altitude 2,040 m), leave the Glacier Blanc path on your right and take the Glacier Noir path on your left.
The path climbs steadily in a straight line along the ridge of the moraine, with the Glacier Noir to the left and the Ravin de l’Encoula to the right.
(2) The ravine levels out at an altitude of 2,445 m, where you can see sheltered clearings beneath overhanging rocks, suitable for bivouacking. You are now at the Balmes de François Blanc, an ideal spot for a picnic.
(3) Continue along the ridge to its end, the highest point of the route at an altitude of 2,550 m.
The return journey follows the outward route in reverse to reach the car park (S/E).
