A nice walk next to the lake of Serre-Ponçon to admire the damselflies
The capped damselflies are a geological phenomenon linked to erosion. The rocks being more or less soft, they do not erode in the same way. After a few thousand years, nature shapes these delicate structures where a large block of stone covers a mineral chimney. The walk is short, you follow a very well maintained path. The site is very easy to access, it is located next to Sauze-du-Lac, you can't miss it. A nice walk if you visit the region.
