Please note regarding signposting: the route is not always clearly marked. At the start in particular, there are no route markings. Make sure you follow the GPS route carefully.
Towards the end of the route (after Lac de la Portette), you’ll find clear yellow markings to follow, as well as signs indicating Lac Blanc and the remaining distance and time.
