3 operators run this water, from 3 h 05 to 5 h 55 — a difference of 2 h 50 on the same crossing. Ios has an airport 36 km from the quay, so this is a crossing you can make one way and fly the other.
One row per operator and speed. Where a service is sold as fast and its average does not clear 45 km/h, the word appears in quotation marks — the boat is fast craft, the crossing is not.
If this crossing does not suit, these quays also reach Ios without a change. It is the question a single-route page cannot answer about itself and an atlas can.

Our records for the Heraklion–Ios crossing were read on 11 August 2026 and describe the network as it ran that week. We hold no month-by-month variation, so this page cannot tell you whether a crossing runs in February.
If you are travelling well outside August 2026, confirm with the operator before you plan around it.
No fares. The choice between Blue Star Ferries at 3 h 05 and SeaJets at 5 h 55 is mostly a price decision, and we hold no prices for either.
No departure times. A weekly rate is a lower bound on how often the crossing runs — never a clock.
