This short route is packed with interest. With the Aiguilles Rouges in close proximity for the full length of the walk and long distance views across the Chamonix valley to the Aiguille Verte and the Chamonix Aiguilles, this is a walk where the pace should be leisurely. There is also the added attraction of a beautifully situated lake with a very pleasant chalet serving excellent food and refreshments.

The walk starts from the upper station of the Chalet de la Flégère to L'Index chairlift, which takes you up to 2385 m. Although signed, the start of the path is indistinct. From the chairlift station go northeast and after 100 metres the path becomes more obvious and is well way-marked with paint flashes on rocks.

The route climbs slightly before descending quite steeply into a rocky amphitheatre where you cross a stream. This could be difficult after heavy rain. The path is always rocky underfoot although much work has been completed to make progress as easy as possible and this evident on the next section where large rocks have been moved to form a rudimentray pavement. Crossing a steep slope the path rounds a corner to reach a signed cairn that marks the entrance to the 'Réserves Naturelle des Aiguilles Rouges'.

Once in the Reserve the path climbs quite sharply for a short way before levelling out with the shores of Lac Blanc and the Chalet soon in view. In good weather you will not be alone and it is worth exploring perhaps spening some time on the shores of the upper lake, which is missed by many visitors.

Things to consider - The chalet refuge is only open mid-June until the end of September. Good footwear is essential on this route as it is rocky underfoot. Early and late season snow may cover sections of the path so walking poles are an advantage.
