You know how Vesuvius exploded at Pompeii around two thousand years ago and spoilt everyone’s day? If the volcano under this caldera blows, it will make Vesuvius look like a child’s temper tantrum. You’re not even seeing the whole caldera here, for most of it is actually under the waters of the gulf. The fields you are here to see is actually the crater of the Solfatara volcano. It does not do much other than emit steam and sulphurous fumes, but that can be pretty cool. The field has many fumaroles and mud pools. The Sanctuary of San Gennaro, a 16th century church, is on the edge of the fields. There’s a campsite if you don’t mind spending the night breathing in sulphur.
