Tips for the Santorini–Kythnos Ferry

  • Arrive at Athinios port at least 45 minutes before departure – the switchback access road down the caldera cliff often backs up in summer, and boarding can start earlier than the printed departure time.
  • If you're staying in Oia, note that no bus runs directly to or from Athinios port – you'll need to change at Fira, adding a ticket and a wait, so a taxi or pre-booked transfer is usually more practical.
  • Collect paper tickets from the Nomikos or Dakoutros travel agency booths at the port as soon as you arrive, rather than waiting until boarding – queues build quickly as departure time approaches.
  • If you're travelling by public bus, stow large luggage in the storage compartment underneath rather than carrying it aboard, as space inside is limited, especially on the busy Fira–Oia route.
  • In Kythnos, the unique double sandy beach of Kolona – a narrow strip of sand connecting the island to the islet of Agios Loukas – is one of the most unusual bathing spots in the Cyclades. The village of Loutra is known for its therapeutic thermal springs, used since ancient times, while the car-free Chora is a classic Cycladic hilltop settlement.
