You push off from Ammoudi as the cliffside villages of Oia recede—whitewashed houses perched above an open bowl of sea. The motor's steady thrum harmonizes with gull calls while the Caldera unfolds: sheer volcanic cliffs, bands of ochre and black, and the island chain that marks the site of a massive prehistoric eruption.
