Cascade de la Lyre, Natural waterfall in Sixt-Fer-à-Cheval, France.

The Cascade de la Lyre is a waterfall in the Giffre massif above Sixt-Fer-à-Cheval, where a torrent dropping from the west face of the Pointe de la Finive crosses the cliffs of the Cirque du Fer-à-Cheval in several jumps. Its main cascade is a wide, dense column of white water falling from the top edge of a dark grey, vertically fractured rock wall patched with yellow-brown lichen, widening into drifting spray at the base. To its right, a much thinner ribbon of water runs down the same cliff, breaking into separate strands near the bottom.

The Cascade de la Lyre lies on a torrent that descends from the west face of the Pointe de la Finive and crosses the cliffs of the Cirque du Fer-à-Cheval in several jumps, in the Giffre massif above Sixt-Fer-à-Cheval. In winter the flow freezes into an icefall that alpinists climb.

In winter the torrent freezes into an icefall that alpinists climb, a use of the site recorded for this waterfall in the Giffre massif. The stream above it descends from the west face of the Pointe de la Finive and crosses the cliffs of the Cirque du Fer-à-Cheval in several jumps, so the fall is one of a series of drops rather than a single step.

Visitors can reach the waterfall through marked trails starting from the main parking area of the Cirque du Fer à Cheval nature reserve. Trail accessibility changes with seasons, and winter visits require proper gear and experience.

In winter the cascade freezes into an icefall that alpinists climb. The stream drops from the west face of the Pointe de la Finive and crosses the cliffs of the Cirque du Fer-à-Cheval in several jumps, so the frozen route follows a line of successive falls rather than one sheet of ice.
