Which months this runs

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

Our records for the Koufonissi–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 SeaJets at 4 h 05 and the slowest at 7 h 30 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.
