Heraklion to Ios Ferry

The Heraklion to Ios ferry links the largest port on Crete with the Cycladic party-and-beach island of Ios, sailing northbound across the southern Aegean. It is a seasonal, summer-only service: departures are concentrated in the high season (roughly late May through September/October) and disappear in winter, so it is not a year-round crossing.

Who operates it and how fast

The route is run by SeaJets using high-speed catamarans such as the Worldchampion Jet and Champions League Jet. These vessels reach up to around 50 knots and carry both foot passengers and vehicles (cars, motorbikes), so you can bring a car between Crete and the Cyclades. There is no conventional slow ferry on this specific pairing.

Crossing time and frequency

Heraklion sits about 75 nautical miles from Ios. A direct high-speed sailing takes roughly 3 hours, but many departures are routed through other Cycladic ports (for example Santorini) before reaching Ios, which can stretch the total journey to five hours or more. Expect on the order of 6 to 7 sailings per week at peak season, almost always with morning departures from Heraklion.

• Departure port: Heraklion (Crete), the island's main harbour
• Arrival port: Ios, in the central Cyclades
• Vessel type: high-speed catamaran (passengers and vehicles)
• Best for: combining a Crete holiday with island-hopping northward toward Santorini, Naxos and Paros

Because timings, exact duration and the number of weekly departures shift with the season and with which intermediate islands each sailing calls at, always confirm the live timetable for your travel dates before booking. High-speed catamarans are also more sensitive to strong summer meltemi winds, which can occasionally delay or cancel departures.
