Santorini

Formed by one of history's largest volcanic eruptions around 1600 BCE, Santorini (ancient Thera) rises dramatically from the Aegean Sea in Greece. Its 9,386-hectare caldera, famed whitewashed Cycladic villages perched at 300m above sea level, black and red volcanic sand beaches, and world-class sunsets over the caldera have made it the Mediterranean's most photographed island.
