This circuit allows you to walk around the lovely Lac de la Mouche where you will be able to enjoy the shade of the surrounding trees.
The Lac de Saint-Ciergues is the smallest of the 4 lakes in the Pays de Langres. With an area of 97 hectares and a length of 2.4 kilometres, it's the most steep-sided and deep lake (nearly 21 metres). It's the only one of the 4 lakes of the Pays de Langres with a brick embankment, which is impressively high.
This provides a lovely walk on the water's edge in a very verdant setting.
