Follow the path uphill through the forest for 50 minutes until it emerges out into the open, at the foot of the Chéserys rock slabs. Traverse along the foot of these to the Aiguillette d'Argentière, a spectacular rock pinnacle which is popular with local rock climbers.

Go past this and up a series of ladders to reach another path which continues to climb all the way to Lac Blanc (2352 metres) via the Lacs des Chéserys. Allow 3 - 4 hours to reach Lac Blanc. The view here is staggering, so grab a drink at the Refuge du Lac Blanc and soak it in.

From the Lac, follow a good path downhill for 1.5 hours to reach the top of the Flégère cable car. Ride this down to the village of Les Praz, 2 kilometres northeast of Chamonix.
