While you are on the boat, just beyond the rock of Dattilo, stop and look around you: all the rocks and isles, each with their own shape and colour, will make you feel like you are standing in the middle of a gallery dedicated to a famous sculptor.
Moor your boat between the rocks of Bottaro and Lisca Bianca, in line with the fumarolic field, and jump in. No free-diving necessary, simply put your ears below the water’s surface to hear the full power of the gurgling sea.
Though not as evident as on the island of Vulcano, the fumaroles between the isles of Bottaro and Lisca Bianca have the “classic” smell of an active underwater volcano, i.e. a smell of sulphur mixed with vaporised sea water.
