Who has visited Naples and is looking for a wildly natural I will recommend a visit to Solfatara on the outskirts of the city. The Solfatara is located within the Campi Flegrei and is one of the 40 volcanoes that make up this area. It is possible to reach the Solfatara through a Mediterranean forest where see the viewpoint where you can closely observe the crater of the Solfatara.
Go up the path you will meet more fascinating sites like the Il Pozzo di acqua Minerale (Well of mineral water), the stone quarries of trachyte, the Stufe Antiche (antique stoves) built in 800 used for thermal purposes to care respiratory and skin illness and finnally to reach the Grande Fumarola with its characteristic smell of sulfur (similar to rotten eggs). The solfatara is not the only natural attraction of the Campi Flegrei just move a bit to be amazed by the scenery and the magic that gives the underwater park – Parco Sommerso della Gaiola.
The entire area of Campi Flegrei was affected over time by the phenomenon of bradyseism (raising or lowering of the ground) because of this phenomenon has been the collapse of the ancient coastline of Pozzuoli, Bacoli and Miseno with relative submergence of Roman villas, tufa quarries, ponds visible along the coast and below the sea surface. The park reveals the beauty of an enchanted world protected for centuries by the ancient sea.
The sunken city of the Roman era is visible flying over Naples by plane, but to enjoy this wonderful place we recommend the glass bottom boat excursion or for more good at diving.
