The Soudeillette is a tributary of the Luzège river which has its source in the peaty bottoms of the Millevaches plateau. The good water quality of the river favours populations of brown trout. The valley is home to many remarkable species, both plants and animals, which is why it has been classified as a Natural Zone of Fauna and Flora Interest. It has also been used by humans to power mills like the one in Pézareix.
