How to Get from Athens to the Greek Islands (2026): Ferries, Flights and Which Port to Use

Almost everyone who visits Athens ends up asking the same question: how do I get to the islands? It sounds simple, then you discover there are three different ports around Athens, two kinds of ferry travelling at very different speeds, and flights that are occasionally cheaper than the boat.

We move people between Athens and its ports all season, so we see where plans go wrong: turning up at the wrong port is the classic, expensive mistake. This guide keeps it clear. Which port serves which island, whether to sail or fly, how long it takes, and how to book without stress.

Athens is served by three ports, and the right one depends on your island. Piraeus is the giant that handles most routes; Rafina and Lavrio are smaller east-coast ports that are closer to the airport and serve specific islands. Booking from the wrong port is the single most common ferry mistake visitors make.

Piraeus is the default and by far the largest. Rafina is often faster to reach if you are coming straight from Athens Airport, and its crossings to Mykonos and Tinos can be shorter. Lavrio is the quiet option for the nearer Cyclades. Always check which port your specific ferry departs from when you book, because some islands are served from more than one.

It depends on the distance and what you value. For far islands like Santorini and Crete, flying saves hours: an Athens–Santorini flight is around 45 minutes versus five to eight hours by sea. For nearer islands, the door-to-door time is often similar once you add airport check-in, so the ferry wins on cost and experience.

One honest point most people miss: island airports are often outside the main towns, so a cheap flight can be eaten up by a long, pricey taxi at the other end. Compare the full door-to-door journey, not just flight time versus sail time.

Ferry times vary a lot depending on the island and whether you catch a high-speed or conventional boat. These are typical ranges for popular routes in 2026; always confirm the exact time for your sailing, as it can change by hour of day and season.

The Saronic islands (Aegina, Poros, Hydra, Spetses) sit close to Athens and make easy short trips or even day trips from Piraeus. The Cyclades are further, so plan your first and last island days around the crossing rather than assuming you will arrive by lunchtime.

This is where the timing gets real, because missing a ferry usually means missing a whole day. From the airport, Piraeus is roughly 60 minutes by road, Rafina about 30 minutes and Lavrio about 40 minutes. From central Athens, Piraeus is 30 to 45 minutes depending on traffic.

For the metro, the blue line (Line 3) now runs directly to Piraeus port, which is a cheap option if you are travelling light. With luggage, a tight ferry connection or an early sailing, a fixed-price private transfer removes the risk. See our detailed guide to the Athens Airport to Piraeus Port transfer for exactly how to time it, and our private transfer routes if you want a driver waiting when you land.

Rafina and Lavrio have no metro link, so from those ports you rely on the KTEL bus from the airport or central Athens, or a private transfer. If your ferry leaves from Rafina or Lavrio, factor that in early; it changes how you plan your arrival day.

Greek ferries come in two broad types, and the choice is a trade-off between time, money and comfort. High-speed catamarans cut the journey but cost more and can be cancelled in strong winds. Conventional car ferries are slower, cheaper, steadier in rough seas, and let you walk around on deck.

If you are prone to seasickness, the larger conventional ferries ride more smoothly than the fast catamarans. If the forecast shows strong winds, the big boats are also less likely to be cancelled.

For summer travel to popular islands, book two to four weeks ahead, and earlier for August or if you are taking a car. Peak sailings sell out, especially on Fridays, weekends and around the 15 August holiday. Outside peak season you can usually book a few days before with no trouble.

Book through a comparison site like Ferryhopper or Direct Ferries, or directly with the operators (Blue Star Ferries, SeaJets, Hellenic Seaways, Fast Ferries and others). Keep a digital and printed copy of your ticket, and note that some routes still require you to collect a paper boarding pass at the port before departure. Check that requirement when you book.

If you would rather not think about any of this on arrival day, tell us your ferry and flight details and we will have a driver meet you and get you to the right port with time to spare. It is the part of the trip where a small margin of safety is worth a lot.
