3 operators run this water, from 4 h 20 to 9 h 05 — a difference of 4 h 45 on the same crossing. Piraeus-Athens has an airport 20 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 Piraeus-Athens without a change. It is the question a single-route page cannot answer about itself and an atlas can.

Our records for the Ios–Piraeus-Athens 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 SeaJets at 4 h 20 and Cyclades Fast Ferries at 9 h 05 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.
