Travel from Cagliari to Iglesiente, one of the oldest historical areas in Sardinia with a wild landscape famous for its mining history. Discover the Porto Flavia mine, an extraordinary monument of industrial archaeology overlooking an incredible coastline with a breathtaking vista of the Masua Sea.   Built in 1924, Port Flavia is an incredible work of engineering suspended between sky and sea that made it possible to load minerals directly onto the ships. Walk through the 600-meter-long tunnel and discover the history of the mine that remained functional up until the 1960s.  Next, see the Parco Geominerario della Sardegna (Geological and Mining Park of Sardinia), declared a World Heritage Site by UNESCO. After the visit, enjoy a little stop to see the incredible coast of Nebida, walking through the panoramic street in front of the Laveria Lamarmora mineral washing plant before returning to Cagliari.
