This natural wonder is the Tufière de Saint-Ciergues. It is a small tufa formation created by the deposition of limestone on moss, forming a series of small waterfalls. Tuff is a porous stone which gave its name to the site. You can enjoy the view of the tuff and the surrounding forest, but be careful not to step on it, as it is very fragile and needs to be preserved.

This beautiful structure with the architecture of a viaduct is the highest of the 4 dams in the Pays de Langres. It forms the Lac de la Mouche, undoubtedly the most peaceful, preserved and bucolic of the 4 Langres lakes. The dam is surmounted by a small road which leads to Saint-Ciergues, a hillside village with an excellent restaurant.

The tufa are sources that cause calcareous concretions, which give them an unusual appearance. These concretions are sometimes in the form of giant stairs, causing a succession of more or less high waterfalls.
