The trick to the Cyclades isn't choosing one island — it's stringing together three or four with the slow blue-hulled ferries that have linked these whitewashed ports for generations.
Start in Naxos for the long sand beaches and the marble villages of the interior, then take the morning boat to tiny Koufonisia where the water turns an impossible turquoise over a flat sandy seabed.
From there, Amorgos rewards anyone who climbs to the Hozoviotissa monastery clinging to a vertical cliff. End in Santorini if you must, but the real magic is in the quiet stops most cruise crowds skip.
Book deck-class tickets a day ahead in peak summer, carry cash for the smaller harbours, and never plan a tight connection — the Aegean meltemi wind reshuffles schedules without apology.
