fairly flat hike, except for the steep section at the end. To enjoy the waterfalls, do it the day after it rains!

Be sure to arrive early. Despite the large parking lot, it fills up quickly. We arrived at 7:00 AM because of the heat, and there was plenty of room. By noon, when we left, there was a fight for our spot.

Impressive waterfall of several meters in the Cirque du Fer à Cheval.

The Cirque du Fer-à-Cheval owes its name to the semicircular shape of its cliffs. Its impressive height (2,000 meters) gives rise to a multitude of waterfalls, the number of which varies depending on the season. It is very easy to access. Twin to the Pyrenean Gavarnie, it is the most visited and best-known site in Sixt-Fer-à-Cheval. Surrounding the eastern slope of the Giffre Valley, it is an immense limestone amphitheater 4 to 5 km long, whose steep cliffs can reach 2,000 m in height. It is the largest Alpine cirque, dominated by the Corne du Chamois. It rests on the steep slopes of the Tenneverge (2,985 m). In June, more than thirty waterfalls gush from its walls.
