Getting from Syros to Alonissos

If you are heading to Alonissos from Syros you are making your way from the capital of the Cyclades to the most remote of the Sporades group, in the northern Aegean. It has a densely forested coastline, a beautifully preserved old village above the port and a marine park that protects the largest colony of Mediterranean monk seals in Europe.

Take the ferry

There is no direct ferry from Syros to Alonissos. The two islands are in different island groups with no sea connection between them. Getting there means taking the ferry from Syros to Rafina, which runs several times daily in summer and takes around 3 to 4 hours, and then driving to Volos, which takes around 3 to 3.5 hours from Rafina, for the direct ferry to Alonissos, which runs daily in summer and takes around 3 to 5 hours. This avoids Athens and Piraeus entirely. Note that as of 2026 there are no departures from Agios Konstantinos to Alonissos.

Getting there by air

Alonissos has no airport. The nearest airport is Skiathos, with connections from Athens. Syros has a small domestic airport with limited connections from Athens. Taking the ferry from Syros to Piraeus, flying from Athens to Skiathos and then taking the ferry from Skiathos to Alonissos, which takes around 1 to 2 hours, gives a total journey time of around 6 to 7 hours. In Greece, airlines do not operate direct inter island flights.

Your best option

Take the ferry from Syros to Rafina and drive to Volos for the direct ferry across to Alonissos. It avoids Athens and Piraeus entirely and is the most natural approach. If you prefer to fly, take the ferry from Syros to Piraeus and fly from Athens to Skiathos and take the ferry across to Alonissos. If you are traveling with a car, the Volos ferry takes your vehicle directly to Alonissos port.
