A nature reserve of national importance, the Etang de la Gruère is a haven of peace and a true paradise for nature lovers. The path around the lake invites you to discover its special flora and fauna.

The Etang de la Gruère nature reserve covers more than 120 hectares. The peat bog or upland moor extends over 56 hectares and has a nine-metre layer of peat accumulated over 12,000 years (after the end of the ice age). Most of the reserve lies within the territory of the town of Saignelégier but some of it also extends into the territory of the Jura towns of Bémont and Montfaucon, as well as Tramelan in the canton of Bern. It is classified as a marshland of national importance. In the 17th century, an artificial dam was built to operate a mill.
