The Chur Rhine Valley[1] (German: Churer Rheintal, also commonly known as the Bündner Rheintal) is that part of Nordbünden through which the Rhine flows from the confluence of Anterior and Posterior Rhine near Reichenau to the cantonal border near Maienfeld and Fläsch. The plain of Bonaduz and Rhäzüns also belongs to the Chur Rhine Valley and forms its southern end. The valley is part of the Alpine Rhine natural landscape.
