Analysing terrain data
5 - 6
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.
From wherever you stayed in the Montroc/Le Tour/Les Frasserands area, make your way to the little village of Trélechamps, a kilometre below the Col des Montets.
Take the path on the west side of the road, signposted for Les Chesereys and La Flégère.
Climb up on this path for 1 hour to reach the distinctive and dramatic Aiguillette d'Argentière - a 20 metre high rock pinnacle.
Sit and watch the rock climbers on this (it is popular on sunny days) and then continue up the path and up a series of ladders to get above the rock cliffs of Les Cheserys.
From here, follow the path as it undulates to Flégère.
The views throughout, particularly of the Glacier du Tour, Aiguille Verte and Grandes Jorasses, are staggering.
If you don't like the sound of ladders, it is possible to go up to the Col des Montets and go to the Flégère from here, thereby skipping out the ladders.
There is also an option of detouring from the top of the ladders up to Lac Blanc, one of the most famous and scenic spots in the Chamonix Valley.
It is a roughly 2 hour detour to the Lac and it's well worth the effort if your legs have enough energy left in them.
Whichever option you choose, ride the Flégère cable car down to the village of Les Praz and stroll triumphantly back into Chamonix.
