The Kythnos to Lavrio ferry is a Cyclades-to-Attica ferry connection to Lavrio. It is currently available through the Direct Ferries booking inventory and was rechecked for EUFerry on 20 September 2026. Because ferry schedules are dynamic, the live booking results should always take priority over a typical frequency quoted in a guide.
For planning purposes, the crossing is typically about 1 hour 10 minutes to 2 hours 45 minutes, with around 11 sailings a week. The current operators listed are Magic Sea Ferries, Triton Ferries, Goutos Lines and Karystia Travel. Travellers should compare the exact departure rather than choosing solely by headline duration: check-in time, baggage conditions, vehicle acceptance and arrival port logistics can be just as important.
This guide is designed around the questions most people search before booking: how long the ferry takes, which companies operate it, whether foot passengers or vehicles can travel, what each port is like, and how to protect an onward connection. Search your real date in the ferry search above to see the services actually on sale.
