From Vallouise, take the D994E towards Ailefroide and then Pré de Madame Carle. Park in the car park near the refuge chalet. The entrance fee to the car park is £2.
(S/E) From the Refuge de Madame Carle, take the path to the north-west towards the glaciers.
This crosses the Momie and Glacier Noir torrents and then winds its way upwards.

The trail climbs steadily in a straight line along the ridge of the moraine with the Glacier Noir on your left and the Ravin de l'Encoula on your right.
(2) The latter turns into a flat area at an altitude of 2,445 m, where you can see shelters sheltered by overhanging rocks where it is possible to bivouac. You are now at the Balmes de François Blanc, an ideal place for a picnic.
