3 operators run this water, from 15 min to 12 h 10 — a difference of 11 h 55 on the same crossing. Lavrio has an airport 27 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 Lavrio without a change. It is the question a single-route page cannot answer about itself and an atlas can.

Our records for the Ios–Lavrio 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 15 min and Blue Star Ferries at 12 h 10 is mostly a price decision, and we hold no prices for either.
No departure times. No rate is held for this pair either, so we cannot say how often it runs.
