The village of Nans-sous-Sainte-Anne is remarkable for the scale of its landscapes, the rhythm of the mountains and depressions. It knows how to combine in a restricted space the charm of the foliage and the fir trees with the austerity of the rock walls, the impetuosity of the waterfalls with the intimacy of the undergrowth, the mystery of the caves with the picturesqueness of the belvederes.
