This challenging day begins with a tough ascent from Tré-le-Champ to Lac Blanc, a gorgeous alpine lake, before descending down to La Flégère and further on to Planpraz, from where you take the cable car down to Chamonix. Unfortunately, the Flégère cable car is closed in summer 2019 for refurbishment.
This challenging hike will take you from the tiny village of Tré-le-Champ up to Lac Blanc, with beautiful views of Mont Blanc and other surrounding snowy peaks. Once at the top, you will walk by several glistening Alpine Lakes, with Lac Blanc, and the infamous Refuge du Lac Blanc (at the time of writing - closed for business). After a long climb, with some technical ascents using ladders and hand/foot rails bolted into the rock, and tough underfoot conditions, you will descend back down into the valley where you take the cable car back down to Chamonix from Planpraz.
Lac Blanc is by far the highlight of this day as it not only represents the highest point of your walk, but also offers beautiful views of the snowy peaks and a serene alpine lake - the perfect spot to have a picnic lunch.
There are some ladders and parts where the path veers over some boulders, so sturdy hiking boots are essential and walking poles will be very useful for the ascents/descents. The ascent is steep, and if it is sunny, you will need plenty of water. Make sure to stay hydrated and pace yourself as you go up the mountain, as the climb is both steep and long.
Make sure you check the times for the various cable cars down and budget plenty of time, so that you don’t end up getting stuck on top of the mountain! Check the 'Getting there section' for more details. Operating dates and times can be checked: http://www.compagniedumontblanc.fr/en/portal
When descending, there are oftentimes multiple ways down. Make sure to take a safe route and look out for rockpiles, which help to distinguish the most accessible paths.
Bring a jacket or windbreaker, as it can get quite cold at the top, and there will most likely be snow around the Alpine Lakes. Walking boots are essential for this walk, and walking poles are highly recommended, especially for some of the more technical descents.
For this walk it is important to bring plenty of water, lunch, and snacks for the day ahead. We suggest bringing these from Chamonix as options are limited around Montroc. There are no other places to stock up on food (at the time of writing, Lac Blanc is closed for business)
Points of Interest
At 2352 meters, Lac Blanc is a serious trek away, but it’s worth every step – this alpine lake is one of the most beautiful in the vicinity.
One of the greatest beauties of the Réserve Naturelles des Aiguilles Rouges, Lac Blanc is an alpine lake famed for its beautiful views over the imposing Mont Blanc, at the other end of the valley. The combination of endless views and extreme serenity make this a place that hikers often love to stop at. The Refuge du Lac Blanc, equally as iconic, is also famed for its hospitality and spectacular photographs, combining the remoteness of the refuge with the rugged mountain landscapes surrounding it.
