Volcanic Wonders

The Phlegraean Fields, or Campi Flegrei, is a vast volcanic caldera west of Naples characterized by diverse geothermal activity. This list features key geological sites including Monte Nuovo, a cinder cone formed during a 1538 eruption, and the Solfatara crater with its active fumaroles. Visitors can explore the Astroni nature reserve located within a volcanic crater, the ancient Roman military engineering of the Grotta di Cocceio tunnel, and historic thermal springs like the Stufe Antiche that utilize natural volcanic steam.
