Getting into a lava tube can be a memorable experience. In fact, lying below the lava soil creates the feeling of coming into contact with the centre of the earth. The tunnel is formed due to the cooling of the lava flowing into the duct and its drainage and erosion mottle its walls. We will illuminate the path with lanterns in order to appreciate the details. Reaching the Valle del Bove, an ancient depression formed 9,000 years ago, will take us back to the time when a massive volcano dominated the whole area. Observing the formation of the fracture from which the lava came out in 1928 will complete the experience and will close the itinerary.
