The Borgne is a river in the canton of Valais , about 30 kilometers long , which is created by the confluence of the Borgne de Ferpècle and Borgne d'Arolla near Les Haudères .

Their source rivers, which drain several glaciers between Dent Blanche (4357 m) and Pigne d'Arolla , are called Borgne de Ferpècle (from Ferpècle ) and Borgne d'Arolla (from Arolla ). Their confluence is at the village of Les Haudères . The Borgne flows first through a high valley and then through the deep gorges of the Val d'Hérens and finally flows into the Rhone near Sion . The river is diverted to the Lac des Dix in its upper reaches . The water quality of the river is slightly polluted. The river can be canoeed in spring when the snowmelts (May – June) or on hot summer days. The most important tributary is the Dixence , which comes from the Lac des Dix.
