The exposure grade describes the potential consequences of falling or slipping off the path.

Low Exposure: The path is on completely flat land and potential injury is limited to falling over.

Medium Exposure: The trail contains some obstacles such as outcroppings and rock which could cause injury.

High Exposure: Some trail sections have exposed ledges or steep ascents/descents where falling could cause serious injury.

Extreme Exposure: Some trail sections are extremely exposed where falling will almost certainly result in serious injury or death.


Start in the village of Argentière, 10 kilometres northeast of Chamonix, which can be reached by car or bus.

Just before reaching the Restaurant des Chéserys, at the northern end of the village, there is a carpark on the left and at the back left of this, a path leading into the woods.

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.
