Vallée de la Maronne
At the Col de Néronne, we leave the Mars valley to go into the Maronne Valley (Saint-Martin-Valmeroux). The road from Salers is one of the most beautiful in the Cantal. From the pass you can see the Roc des Ombres (1633m) where the river has its source. It is a glacial valley with different landscapes: forests on the North side and pastures or mountainous moors on the South side. Downstream, the valley becomes wider and the waters flow into the Enchanet reservoir.
