Santorini is a crescent-shaped caldera left behind by one of the largest volcanic eruptions in recorded history. The blue-domed churches and whitewashed houses of Oia and Fira sit on cliffs high above the water. Cruise ships anchor inside the caldera and tender passengers ashore to reach the black-sand beaches, the Bronze Age ruins at Akrotiri, and the island's restaurants.
