This itinerary passes through places of great natural value and industrial archaeology sites, including the San Luigi Mine and the old mining buildings of Pranu Dentis. The route is located in a protected area, the SCI (Site of Community Importance) called Costa di Nebida.
The route, which intersects with trail 303, is a variant of trail 302, as it allows you to return to the starting point via Gutturu Cardaxius and to reach the coast of Cala Domestica, shortening the journey time by about 30 minutes.
