We are in the territory of the Meilogu , a mainly volcanic area that with the characteristic conical hills make their appearance very unique in the context of a geologically ancient land. In this area the soils are among the most fertile and the whole area is rich in pastures. In our itinerary we have analyzed a large area and for this article we have taken Cossoine as a reference point from which to start an open-air museum. Before making the itinerary I asked myself, what to see in Cossoine and especially in the surrounding areas? Many answers, many fascinating places and many emotions told in this article made available to everyone.
