The lakes of Clairvaux - the large and the small lake - are located in the heart of the country of lakes and waterfalls of the Jura. If they serve as a base for many vacationers and hikers, they are also important ecosystems for birds, amphibians especially in the wetlands that connect the two lakes. The surrounding paths offer very beautiful views of these two stretches of turquoise water.

I am a native of Bonlieu: the lake is magnificent but I do not recommend swimming there. Indeed, this undeveloped lake has currents created by underground rivers and can lead experienced swimmers to the bottom. There are plenty of lakes in the area suitable for swimming, keep this one to dip your eyes into.
