Ferry from Kos to Syros (Ermoupoli)

Kos to Syros is a long westbound crossing linking the Dodecanese with the Cyclades, run by Blue Star Ferries with the Blue Star 2. The passage takes around seven and a half hours with calls at islands along the way, so it is most of a day at sea. Fares start around €60.

Ermoupoli, the port and main town of Syros, is the administrative capital of the Cyclades and looks quite different from its neighbours, built in grand neoclassical style from an era of real commercial wealth. Two hilltop quarters rise above the harbour, Catholic Ano Syros and Orthodox Vrontado, each with its own church at the summit. The town has genuine cultural life, including an opera house and several museums.

Sailings run a couple of times a week in season. The current timetable and fares are shown in the tables below. Syros is a major Cycladic hub, so onward connections to Mykonos, Tinos, Paros, Naxos and Piraeus are easy to pick up on arrival.

Hiring a car

Can you rent a car in Syros?

Yes, and rental desks cluster right in Ermoupoli, a short walk from where the ferry docks. Syros Town itself is easily walkable, but a car earns its keep for reaching Kini, Galissas and Poseidonia beaches, each 8-10km away on the other side of the island.

Can you rent a car in Kos?

Yes. The ferry port sits right in Kos Town, about 2km from the centre, a 20-25 minute walk or five-minute drive, with rental desks nearby. Buses run regularly between the main towns but thin out fast once you leave them, so a car is worth it if you want to reach the Asclepion, Mount Dikeos villages or the quieter beaches.

Frequently Asked Questions

Tips for the Kos to Syros ferry

• The harbour sits right beside the medieval Castle of the Knights, with ticket agencies lining the waterfront. For domestic sailings on Dodekanisos Seaways and Blue Star ferries, arrive at least 30 to 45 minutes before departure to buy tickets and locate your berth.
• If you are travelling on to Kalymnos, check which port is printed on your ticket – many sailings, including the frequent local car ferries, depart from Mastichari on Kos's north-west coast, not from Kos Town harbour.
• Left-luggage lockers at Kos Town port are limited, so don't rely on finding one at short notice; pack light enough to carry your bags the short walk from the harbour into the old town yourself.
• If cabins are sold out, reserve an airline-style reclining seat rather than deck class – it is far more comfortable for a full night's crossing.
• Once you arrive in Syros, the elegant capital Ermoupoli – with its grand neoclassical town hall, marble-paved Miaouli Square, and the Apollo Theatre – reflects the island's prosperous 19th-century history as the commercial centre of the Aegean. The hilltop medieval settlement of Ano Syros, built by the Venetians around 1200 CE, offers a contrasting older layer of island history.
