Hiking
The Grand Maclu, the Lac d'Ilay and the Petit Maclu together form a string of lakes connected by a small stream.
Located in a Natura 2000 area, the lake offers an exceptional habitat for many animal species. These wetlands are particularly rich: you can see water lilies, reeds, rushes or even sedges.
