Roc Nature Trail, a lateral valley of Orco Valley, develops in an environment where the centuries-old presence of man has left precious historical evidences, like the quarters, the woods, the shape of the fields, and the terracing.
Moreover, the elements of the natural landscape, such as fauna, flora, geological formations protected by the Park offer interesting learning opportunities. The itinerary follows a well-signaled path leaving upstream from Noasca and arriving - through a ring-route - at the country hamlet Pianchetti.
