Description

In the heart of the Aiguilles Rouges nature reserve, the Lac Blanc circuit is a beautiful course with a view of Mont Blanc.

Please note: in order to preserve mountain lakes, swimming is now prohibited at Lac Blanc and Lacs des Chéserys by prefectoral decree.

From the chairlift station, head right downhill towards Lac du Fouet. The path leads to the bottom of the Combe des Crochues. A flanking traverse leads to a rocky spur which must be skirted and which marks the boundary of the Aiguilles Rouges Nature Reserve, where Lac Blanc is located. This traverse becomes ascending and, at the level of a large cairn, joins the path coming from Flégère, which leads to the refuge and the lake.

Further information available from the Tourist Office or the Office de Haute-Montagne and in our trail guide.
Please note: trail conditions are subject to change, so check before you set off.
