Santorini is an island in the southern Aegean Sea, about 200 km (120 mi) southeast from Greece's mainland. It is the largest island of a small, circular archipelago which bears the same name and is the remnant of a volcanic caldera. It is deliciously different.
Geographical newness is in part to thank. The island's popular black volcanic Perissa and Kamari beaches are big draws, as is its arguably most famous Red Beach near Akrotiri.
