First it flows northeast, more or less along the French-Swiss border (forming the border for approx. 40 km). Near Montbéliard it turns southwest, until it flows into the river Saône in Verdun-sur-le-Doubs, approx. 20 km northeast of Chalon-sur-Saône. Its entire course resembles an inverted letter U, with the northeastern corner the only point at which the Doubs flows into Switzerland as far as Saint-Ursanne.
