This walk offers a very deep lake of 87 ha, nestled in a basin of the Chandouille in a setting carpeted in heather in the heart of the Plateau de Millevaches. A place much appreciated by fishermen for the diversity of its fish. This peat bog is a peaty alveolus occupied by wet moors and dry heaths. The wet moors are home to areas of unstable peat bogs where Drosera grows. The presence of juniper bushes makes this site remarkable because it is very rare in Limousin.
