The walk leaves at the campsite Bordes de Graus and goes by a nice path along the reservoir Baratge de Graus and then after a long bend to follow the banks of the Noarre river. Eventually you come to the bridge over the Noarre and you already have a beautiful view of the plain of Bordes de Noarre. In the west you can see the 2847 meter high Mont-Roig. Once you are through the hamlet, the path curves towards the waterfall of Noarre, especially in the spring it is really impressive. The last part you pass the ruins of Bordes de Pontells to reach the starting point again.
