The volcano of Santorini is one of the few active volcanoes of Greece. It erupted once in 1500 BC and the eruption was so strong that the size of Santorini changed (from circular it became of a strange shape), the smoke recovered the entire island and many neighbouring islands and the waves caused by the eruption arrived all the way to Crete and were one of the most important cause of the destruction of the Great Minoan Civilisation. With the power of the eruption the volcano went into the sea.
The volcano is lying in the centre of the basin of Santorini and has formed, after its eruption, two small islets of frozen black lava called Palea Kameni (Old Burned) and Nea Kameni (New Burned) which are respectively 2000 years and 500 years old.

Santorini's volcano is called Caldera and has become one of the main attractions of Santorini; thousands of visitors visit it every year by regular boat excursions which let them on Nea Kameni (the central part of the volcano) where they can walk through this amazing landscape reminding of a lunar one. The volcano crater can be seen as well as some holes with sulphur steam coming out of them.

The view from the volcano over the villages of Santorini perched on the cliffs is really worthing the trip as is the view from the villages to the volcano.

Fishing boats also give the possibility to reach the surroundings of the oldest volcano (Palea Kameni) where visitors can enjoy an unforgettable swim in the deliciously hot waters.
