Park in Saint-Véran (parking is compulsory) and head to the Refuge de la Blanche the day before.
(S/E) From the refuge, head due south, skirting around Lac de la Blanche. At the junction of the paths, turn right and tackle the tight but manageable hairpin bends. Follow the yellow markings until you emerge into a large clearing, a junction of paths.
(1) Leave the yellow markings, which indicate the route to Col Blanchet. Turn left and you will immediately reach Lac Blanchet Inférieur. Go round it on the left and then follow the cairn-marked path which, after a short climb, leads to Lac Blanchet Supérieur.
(2) Continue along more or less marked but cairn-marked paths. These paths are almost flat but cross scree slopes that are not particularly dangerous but require careful attention. They all end at Col de Saint-Véran.
(3) From here, take the yellow-marked path on the left to begin the descent. Further on, you will reach the junction with the path leading to the Refuge de la Blanche (signposted).
(4) Turn left again and complete the return to the Refuge de la Blanche via an easy descent along the path through the mountain pasture (S/E).
Note: you will also need to make your way from the refuge to Saint-Véran; for this, see § Practical Information
