9Santorini, Greece

Santorini, with its blue-domed churches and whitewashed buildings, is one of the world’s most recognized cliff-side destinations. Located in the Cyclades, this volcanic island has a dramatic caldera view, a legacy of ancient volcanic eruptions.

Towns like Oia and Fira are built along the steep cliffs, providing spectacular views of the Aegean Sea, particularly during sunset. Santorini’s cliffs are home to luxury resorts and restaurants that seem to hover over the deep blue water, creating a dreamy escape for visitors.
