Diamanti Beach lies at the southern end of the Kanapitsa peninsula on Skiathos and is also known locally as Koutsouri. It is a compact sandy cove backed by the green slopes characteristic of the island’s southern coast. The beach feels removed from the main road corridor, yet it is not an undiscovered wilderness: excursion boats, private craft and a seasonal tavern can make it lively in high summer.
The two names matter when navigating. Some maps and Greek guides use Koutsouri, others Diamanti or Diamandis, and boat operators may recognize one form more readily than another. Verify the destination when boarding so that it is not confused with Kanapitsa Beach or nearby Tzaneria. The map point belongs on the end of the peninsula between better-known southern bays.
