Tinos and Syros face each other across a strait of about 12 nautical miles, and the ferry between them is one of the simplest in the Cyclades. Tinos is the island of marble villages, dovecotes and the great pilgrimage church in its Chora; Syros is the administrative capital of the Cyclades, with the neoclassical town of Ermoupoli rising from its harbour. The two make an easy, uncrowded pair for travellers who want character more than beach clubs.
The backbone of the route is Blue Star Ferries, whose conventional ships ran every day in almost every month of last year's data, with six days a week in July. From May to September Seajets adds high-speed sailings, two to five days a week depending on the month. On 12 August 2026, the day we sampled, there were three departures from Tinos: Seajets at 13:00 and 16:10, and the Blue Star Paros at 15:00.
It is also a cheap crossing. Ferryhopper listed one adult from €4, two adults from €8, and two adults with a car from €22.50 when we checked. The high-speed boats charged €10.90 to €18.10 in the monthly table, so the time saved by taking Seajets costs little extra either.
Because boats run all year, this is one of the few Cyclades crossings you can plan in winter without worrying about gaps. Syros, with its airport and daily boats to Piraeus, also works well as the last stop of a trip that started on Tinos.
