What you don't see when you walk here: this lake exists thanks to sheer stubbornness. When the La Joyante River was dammed in the 1970s, no one believed the lake would ever amount to anything. Too isolated, too wild. But nature had other plans. Today, the water is so calm that you almost forget how much effort it once took to tame this landscape.

You hear it before you see it: the water rushing past the rocks far below. The dam itself isn't a thing of beauty, but the contrast with the still lake above is precisely what makes it special.

Walking above the water Hidden among the greenery, you'll find this impressive suspension bridge connecting the two shores of Lac de Sidiailles. It wobbles slightly as you walk across it… The bridge is part of the walking path around the lake and offers one of the most beautiful views of the valley and the granite cliffs.

Hidden among moss and rocks lies this medieval castle. Quiet, mysterious, and almost swallowed up by nature. What many people don't know: beneath these ruins lies an ancient underground passage that once connected the castle to the village of Saint-Éloy-d'Allier. An escape route? A smuggling trail? No one knows for sure...
