Iconic white-domed churches, caldera sunsets and volcanic black beaches
Santorini is the most dramatic island in the Aegean — a crescent of sheer volcanic cliffs rising from a caldera formed by one of history's greatest eruptions. The whitewashed villages of Oia and Fira cling to the rim like icing on a wedding cake, their blue-domed churches catching the light at golden hour in ways that fill a million Instagram feeds. Below the cliffs lie striking beaches of black, red and white volcanic sand, while the island's wines — grown in ancient circular baskets to protect vines from the Aegean wind — are among Greece's finest.
