Continue from the Valle dei ferriere through the long, winding Valle dei Mulini which abounds in lemon groves and trough which the Canneto stream flows. Remains of a former ironfoundry on the higher part of the valley can still be seen, along with the ruins of an aqueduct and what remains of the many paper factories which made Amalfi paper famous with the Curia and religious institutes up to the XII century.
This 3 hour hike starting from Minuta and then Pontone, leads down old steps and along good, sometimes shaded paths through lemon and citrus groves and then along rocky slopes to the Valle delle Ferriere Nature reserve, a wooded area with tall chestnuts trees, natural springs and waterfalls. The valley is surrounded by the high ridges of Mount Cervigliano. It resembles a deep, southfacing amphitheatre surrounded by high cliffs and has an unchanged microclimate which allows for the preservation of the Woodwardia radicans, a rare type of long-leafed fern from the preglacial age.
