Vesuvius

The Vesuvio is the most famous volcano of the world and one of the most dangerous because it is still active.
The Vesuvio dominates the landscape of Naples and its last eruption in 1944 blasted open the cone and the plume of smoke that had long been a constant reminder of the peril also disappeared.
Along the crater border, you can admire the entire Gulf of Naples and if the weather is good and clear you can see the isle of Capri and the isle of Procida, also.
