Sources d'Arcier

The sources of Arcier are three karstic sources resulting from a hilly circus of trees and green forests. They meet after 300 meters and flow into the Doubs. Natura 2000 site, the spring water comes from the natural drainage of the watershed of the Saône-Nancray plateau and is filtered by the Saône marshes.

The three Arcier springs are fed by the infiltration waters of the Nancray plateau. Shortly after they gush out of the mountain in beautiful waterfalls, they come together to form the Arcier stream, which quickly flows into the Doubs. They have been known since antiquity, and supply Besançon with water via a Roman aqueduct of which remains remain. Currently, a trout fish farm benefits from its pure, fresh waters.
