Le Lac Blanc
Hiking with a view!
Get ready for a hike over the balconies of Mont-Blanc and the Aiguilles Rouges.
Lac Blanc can be reached with a little effort via various routes from the Chamonix-Mont-Blanc valley.
If you have children, or are new to mountain hiking, you may prefer to start from Les Praz de Chamonix-Mont-Blanc and take the Flégère gondola. From the top of the gondola, it's a two-hour hike to the lake.
If you're a sporty hiker, Lac Blanc is also accessible from the Col des Montets or Tré-le-Champ. If you choose one of these itineraries, be careful: technical and sometimes aerial, they are not suitable for everyone!
Please note: high-altitude hikes such as Lac Blanc and Tour du Mont-Blanc are only accessible during the summer and autumn seasons, depending on snow conditions.

Le Lac Blanc et le télécabine de la Flégère
Lac Blanc is the promise of astounding panoramic views of the glaciers and the finest summits of the Mont-Blanc Massif. Early in the morning, you might spot the ibex or catch a glimpse of the marmots enjoying the stillness of dawn.
You’ve made it! Now, sit down on a rock and admire the stunning natural surroundings.
We usually just say Lac Blanc, but there are in fact two lakes – the lower lake and the upper lake.
And upstream, the Chéserys lakes also provide a wonderful viewpoint over the Massif – definitely worth a visit!
To really enjoy your trek, make sure you are wearing appropriate footwear and take refreshments with you.
You will come home with some wonderful memories… and will be keen to do it all over again!
