The Island Vulcano is the southernmost of the group and in many ways the strangest. It is composed of extinct craters and one active craters. It is separated from Island Lipari by a narrow channel which is free from dangers. The island rises to its highest elevation in the south at Monte Aria. The northern end is dominated by Gran Cratere, an active crater still standing as it appeared in the eruptions in 1888 and 1890. Bubbling mud pools and hot mineral springs bubbling up from the seabed make it a fascinating place. If it looks like a lunar landscape then the impression is only reinforced by the overweight warm grey mud for its therapeutic effects.
