Travelling between panoramic views, rivers and verdant surroundings, this circuit will help you to discover the Lac de la Mouche and its hills.
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). Created between 1882 and 1889, it collects the water from the Mouche and the Morgon, which cover a basin of 6500 hectares and have a capacity to hold 8,648,000 m3 of water. With few facilities provided, it is one of the wildest lakes in the Pays de Langres, reserved for fishing and hiking.
The Sénance source, which is situated to the east of Courcelles-en-Montagne, is sheltered by a deep forest, Bajocien cliffs and rocks.
It is marked out by a wooden notice which also mentions a swamp that it is inadvisable to go to. The clear water, which escapes from a small black opening, weaves its way between foam-covered stones and then reaches a section of the path, so you have to walk on the edges if you want to keep your feet dry.
