Serifos is a western Cycladic island of bare, rugged hills and a hilltop Chora that looks down on the port of Livadi. Syros sits east of it in the heart of the group, with Ermoupoli, a stately port town and the administrative capital of the Cyclades, and ferries to the busy central islands. Heading from one to the other is a natural move if you started in the quiet west and now want Tinos, Mykonos or Paros, or simply a town with some life in it after a week of beaches.
On the map they are not far apart, but the ferry network does not link them in any way we can document. Ferryhopper had no route page for Serifos to Syros in either direction when we checked on 24 September 2026, and we have no sampled timetable for a direct boat. Older listings on our own site could not be matched to any dated timetable, so we have left their figures out.
The good news is that the route through Piraeus is dependable almost all year. Boats leave Serifos for Piraeus on 5 to 7 days a week in every month, and Piraeus has at least one sailing to Syros every single day. On high-speed boats you spend about four hours at sea; on conventional ships closer to seven or eight. Either way, with an early start you can wake up on Serifos and have dinner in Ermoupoli.
From May to September there is a second option through Lavrio, the smaller port south-east of Athens, though the Lavrio to Syros ship only runs on 2 to 3 days a week, so it suits fewer dates. And always search for a direct sailing first, in case one appears for your date.
