Known for its waterfalls and ancient ferns, the valley once hosted an ironworks and several lucrative paper factories powered by water. The damp, green, secluded protected area of the nature reserve is home to ancient species of ferns and include the woodwardia radicans. A unique environment and that is not to be missed. This is a circular tour starting from the hamlet of Pontone and it combines the upper and lower section of the valley.
