7Santorini

Famous for its whitewashed villages perched above the caldera, Santorini also offers some of the deepest blue waters in the Aegean.

The volcanic origins of the island give the sea here a dramatic intensity, especially when viewed from Oia or Fira at sunset. Beaches like Red Beach and Perissa may have dark sand, but the surrounding waters gleam in contrast, creating striking scenery. Santorini’s blue seas are just as iconic as its sunsets.
