Tips

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.

Lacs de Maclu are two adjacent lakes in the western part of the French Jura, in the Jura department of Franche-Comté. They are located at an elevation of 779 m in a depression in the High Jura, in the region of the Five Lakes near Le Frasnois, about 12 km south of Champagnole.

The Petit Maclu, located to the northeast, has an area of 5 hectares, a length of about 500 m, and a maximum width of about 120 m. Its greatest depth is 11 m. It lies entirely within the municipal territory of Le Frasnois.
