This route can be rather challenging, but thanks to the extensive network of trails, it can be adapted in a number of ways to suit your tastes.

Description

For instance, the climb to Lac Blanc can be cut in half by taking the Flégère cable car. If you choose not to take that option, follow the shaded trail that will eventually take you to a rather boring road for the last bit to La Flègère.

From there, a nice traversing trail with open views takes you to Tête aux Vents where you'll catch up with the throngs of hikers on the way to Lac Blanc. The first stop will be the Chéserys lakes, though. Then you'll need to climb a pair of steel ladders before a steep ascent in order to reach the second lake on your day's menu. Be sure to climb a bit higher than the lakes, as it's less crowded and the view is more majestic You might as well climb an extra 15 minutes to check out the smaller lac de Persévérance.

The next goal is the Col de la Glière, reached via a long and fairly technical trail that gets steeper once you've passed l'Index. The final few meters below the col are exposed, but steps and chains have been installed to assist hikers.

From the col, the Lacs Noirs are 15 minutes away. Otherwise, you can just keep going towards Lac Cornu through the most technical part of the route, consisting of huge rocks piled on top of each other. This part of the run should help you understand why the Trail des Aiguilles Rouges is considered by many to be the most difficult race in the area.

At the col, you'll have many options to choose from for the descent. The most enjoyable one follows a narrow technical trail to Planpraz, before retracing the vertical kilometer course for a while. Don't forget to take the left trail halfway down, as you'll want to follow the petit balcon sud trail in order to get back to the car park.
