The Fer à Cheval is the largest mountain cirque in the Alps. Ringed by towering cliffs, the cirque is breathtakingly beautiful throughout the year but it is most spectacular in the spring, when melting snow swells its waterfalls to majestic proportions.
Lying at the eastern end of the Giffre Valley, the cirque forms an immense amphitheatre almost 5 km across and bounded by 500- to 700-m high limestone cliffs. In June, dozens of waterfalls cascade down these huge walls. The Fer à Cheval attracts large numbers of visitors and is twinned with the Gavarnie Cirque in the Pyrenees.
