5. Volcanic eruptions at Stromboli, Italy

A fireworks show millions of years in the making.
 

 

Part of the Aeolian Islands off the coast of Sicily, Stromboli is a small volcanic island with several hundred brave inhabitants.

Unlike most volcanoes, Stromboli's is constantly spewing lava fountains, gas and ash. Fascinating for volcanologists, but also great for day-trippers who fancy seeing live lava action.

For natural fireworks, take a boat trip around the island at night.

Fee: Boat trips cost €15-20 (US$21-28) per person.

Arrange boat tours from harbors on the north coast of Sicily (Messina, Cefalù, Palermo). www.swisseduc.ch
