The wooden boat eases out of Agia Anna at first light, hull tapping a steady beat against a bright Aegean. Salt air sharpens the edges of the day: fishermen’s buoys drift lazily as the crew points the bow toward the Small Cyclades. Turquoise stretches outward, and the first plunge into glassy water feels like crossing an invisible threshold.

History
The Cyclades have a long maritime history; these islands sustained fishing and small-scale agriculture, with stonework and port traditions shaped by inter-island trade since antiquity.
Conservation
Boaters are encouraged to avoid anchoring on seagrass meadows (Posidonia) and to use reef-safe products; limiting single-use plastics helps protect the fragile Aegean ecosystem.

Bring water shoes
Rocky shorelines and boat ladders make water shoes useful for safe entry and exits at beaches and the cave; they also protect from sea urchins.
Use reef-safe sunscreen
Protect fragile marine life in the Cyclades and avoid oily residue on the boat; reapply after swimming.
Secure a waterproof bag
A small dry bag or waterproof phone case keeps valuables safe during swims and cave entries.
