Ferriere Valley is a unique place for hikers. Along the way there are
waterfalls and water streams that make the valley very cool even in summer. It
is easily reached on foot from Amalfi, with about an hour’s walk. The path runs
through the entire valley with two main tracks, one up from Amalfi, the other
down from Pontone. The most interesting part of the valley is undoubtedly the
Natural Riserva. Due to its geographical position, the area has some peculiar
physical and biological characteristics. Thanks to the rocky ridges that
protect it from the cold northern winds and exposed predominantly to the south,
the Riserva area benefits of a special ecological environment with high
humidity and moderate temperature changes.
The Valley was accurately studied in
loco by the German naturalist Karl Haekel, who discovered that because of the
particular conformation of the territory, and aided by small streams and damp
sea breezes a micro-climate of a subtropical type had formed. An exclusive
habitat for cyclamen, wild orchids, Pteris vittata, Pinguicola hirtiflora, a
small carnivorous plant, Erica terminalis, and a rare species of giant fern of
the tertiary period, the Woodwaria Radicans or Felce Bulbifera Gigante.
