The Lac Blanc lies in the heart of the Aiguilles Rouges nature reserve, across the Chamonix valley from Mont Blanc. The reserve protects a fragile environment: swimming is prohibited in the Lac Blanc and the Lacs des Chéserys, and dogs are not allowed on the path.
From the top station of the Flégère gondola (1,877 m) the path drops into the Combe de la Chavanne, climbs past the Chalets and Lac de la Flégère, runs below the Tête du Aubuy to join the path from Argentière, and reaches the Lac Blanc along a flattening combe. Return the same way; the tourism board also suggests the descent to the Chalets and Lacs des Chéserys.
A steep mountain path; check current trail conditions with the tourist office or the Office de Haute-Montagne before you set off.
