Kastriani Beach lies at the base of the northern cliffs of Kea (Tzia) Island in the Cyclades, directly below the periwinkle-painted Panagia Kastriani Monastery that stands sentinel on an imposing hilltop overlooking the deep blue Aegean Sea. The monastery, dedicated to Kea's patron saint, has watched over this remote shoreline for centuries, accessible only by boat due to steep terrain that preserved the beach's wild, untouched character. Kea, known in ancient times as Hydroussa for its plentiful water sources and thick vegetation, was first inhabited by Water Nymphs according to mythology, then settled by Dorian colonists who fought alongside Athenians at Salamis and Artemisium during Persian invasions, establishing four prosperous city-states including ancient Karthea.
Swimming in the clear Aegean waters attracts boaters and adventurous visitors who anchor offshore to access this small sandy beach with wild beauty. Snorkeling reveals rocky underwater formations and marine life thriving in the unspoiled coastal environment protected by its isolation. The beach serves as a peaceful anchorage for sailing vessels exploring Kea's coastline, and nearby Spathi Beach offers accessible alternatives with taverna facilities. Hiking trails across Kea's 12 designated paths provide land-based exploration opportunities, while the monastery above offers stunning sea views and spiritual heritage. The beach's boat-only access ensures tranquility and pristine conditions rarely found on more accessible Cycladic shores.
