Haut Giffre.

Stretching from the Arve valley to the depths of the Sixt valley, the Haut-Giffre is a majestic mountain massif. It shelters one of the most famous sites in the Alps: the Fer-à-Cheval cirque in Sixt, a breathtaking natural amphitheater. Dominated by the Buet and bordered by the Désert de Platé, this massif offers wild landscapes of rare beauty, between sheer cliffs, hanging glaciers and preserved alpine pastures.
