The story of Lac Blanc

Lac Blanc lies in the Aiguilles Rouges nature reserve, on the sunny side of the valley opposite Mont Blanc. Its name, the "White Lake", comes from the pale rock and the snow and ice that cover it for much of the year.

On a still morning the water reflects the Aiguille Verte, the Grandes Jorasses and Mont Blanc itself, making it one of the most photographed views in the Alps. A small mountain hut, the Refuge du Lac Blanc, sits beside it.
