Stromboli is a strato volcano which rises from the seabed to a height of 2400 meters, 924 of which are above sea level. The island covers 12.5 sq km and is 25 times smaller than the volcano's base area under sea level. Stromboli is a part of the Eolian Islands, all of which are volcanic in origin, and have been included on UNESCO's World Heritage List for their priceless geological value.

Stromboli is one of the world's most visited volcanoes due to its relative accessibility on foot, and its constant form of activity over the last 3000 years.

Despite its active volcanic nature and its harsh and rocky mountainside, the island is host to a rich and endemic vegetation, such as the Cytisus aeolicus and the Centaurea aeolica. It is also host to different bird species which nest here and it is not uncommon to see a Raven, an Hoopoe or a Peregrine. In spring Stromboli is a heaven for various species of migratory birds as it is situated on their migratory passage route; with a binocular it is perfect for birdwatching.
