A small but splendid body of water, Lac Bleu enchants hikers who are fond of mountain lakes and also impresses visitors who stop off at the Plan de l'Aiguille on their way up to the Aiguille du Midi.
An easy trail that starts from the arrival point of the Plan de l'Aiguille cable car (about 15 minutes), Lac Bleu is set in a beautiful verdant landscape enhanced by the rocks and crystal-clear waters. Sweeping view over the Chamonix Valley.
Tips
Beware, high altitude lakes are fragile! Please respect the area: do not swim or wash your dishes, do not trample the wetlands, do not put water sports equipment (buoys, paddles, etc.) in the water or throw anything into the lake (stones, waste).
