 Taking a northward journey, it flows through the communes of Saâne-Saint-Just, Auzouville-sur-Saâne, Biville-la-Rivière, Brachy, Gueures, Ouville-la-Rivière and Longueil and meets the English Channel between Quiberville and Sainte-Marguerite-sur-Mer.At Longueil, not far from the mouth, the flow is relatively low, at 2.6 m/s, because of the small size of the watershed (270 km), however, at Gueures, on the right bank, a significant tributary, the Vienne river, 15 km in length, joins with the Saane.Like most other rivers in the region, the Saâne is classified as a first class river, offering anglers the chance to catch trout and salmon.
