Karlovassi to Piraeus-Athens

3 operators run this water, from 8 h 15 to 9 h 15 — a difference of 1 h 00 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.

Every way across

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.

Where else these quays go

Which months this runs

Season not heldwe can say when we looked, not which months run

Our records for the Karlovassi–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.

What we do not know

No fares. The choice between the quickest at 8 h 15 and SeaJets at 9 h 15 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.
