Cascade du Sartre is a nice looking waterfall south of Cheylade in the region Auvergne/Cantal, France.
From Cheylade drive south to Le Claux (D62) and take the exit to the right (D262), the sign says “Cascades”. After 350 meters a small parking shows up at the right side of the road (before the lake). From here it is a short walk before you see Cascade du Sartre.
Further down the road there is another nice waterfall, Cascade de la Roche, also easy to reach.
