The Gorges du Fier
A spirited mountain torrent, the Fier rises at Mont Charvin before winding its way through Thônes and Annecy, eventually joining the Rhône near Seyssel. About ten kilometres from Annecy, in Lovagny, it has carved one of the region’s most spectacular natural sites: the Gorges du Fier.
Formed by thousands of years of erosion, the torrent rushes here through a narrow passage, confined between two steep rock walls rising up to 27 metres high. Unique in the Northern Alps, this canyon – often compared to a smaller-scale version of the Verdon Gorge – can be explored on an accessible, family-friendly walk, partly laid out along secure footbridges suspended 25 metres above the riverbed. Halfway along, a ladder carved into the rock bears witness to the power of past floods.
Created in 1869 and lasting less than an hour, this walk offers a striking spectacle: rocks sculpted by water, giant’s kettles, and subtle plays of light and shadow on the stone. The trail ends at the “Sea of Rocks,” a vast mineral maze where the water weaves its way before returning to its natural course.
An impressive and memorable visit, recommended for those comfortable with heights.
