Santorini

Perched on the rim of a submerged ancient volcano, Santorini is the most dramatic of the Greek Cyclades. Whitewashed cube houses spill down cliffs into the deep-blue caldera, and each evening the village of Oia dissolves into one of the world's most photographed sunsets. Beyond the postcard views lie 3,500-year-old ruins at Akrotiri, black-sand beaches at Perissa, and a growing wine trail through sun-baked vineyards of Assyrtiko grapes.
