The motor wakes the morning sea; spray knifes past the bow as the coastline of southern Zakynthos slides into view. Ahead, Marathonisi—known locally as Turtle Island—sits like a white-sand ledger against the blue, and the jagged mouths of the Keri Caves promise cool, shadowed swims. Mizithres’ basalt stacks rise from the water and dare you to circle them closely.
