Tips for the Piraeus–Kythnos Ferry
- Group discounts are available on some operators for parties of six or more – contact the operator directly if you cannot see a group rate online.
- A Force 6 wind produces wave heights of 2–3 metres; even passengers who do not normally feel seasick may be affected in these conditions.
- 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.
