The Greek ferry network covers hundreds of routes and moves millions of passengers every summer, and it is the part of an island trip that first-timers most often underestimate. There is no single operator, no pass that covers everything, and the same crossing can take 4.5 hours on one boat and 8 on another. Once you understand the system, it is also one of the more enjoyable ways to travel in Europe.
The approach to Santorini from the sea, watching the caldera cliffs emerge above the horizon, is an experience that flying over the island entirely eliminates.
What follows is the practical guide: the three Athens ports, how to choose between ferry types, where to book, how Piraeus works, ferry times to the most popular islands, night ferries, seasickness, strikes and cancellations, winter service, and the crossings from Italy and Turkey.
Ferries are usually the budget line that runs over. For how they fit alongside rooms, food and the fees most people miss, see how much a trip to Greece costs. For building your island route, see our Greek Islands Itinerary guide.
Check every operator in one search — compare fast vs conventional, see live prices, and book all your island legs together on Ferryscanner.
One more reason to book through an official platform: dockside "discount" tickets are a known con — our guide to scams in Greece covers the fake-ticket trick.
The Three Athens Ferry Ports (And Which to Use)
Most visitors assume Athens has one ferry port. It has three — and choosing the right one affects cost, travel time, and logistics significantly.
Piraeus (Λιμάνι Πειραιά)
The main port. Serves ferries to: all Cyclades islands, Crete, the Dodecanese (Rhodes, Kos, Patmos), Saronic islands (Aegina, Hydra, Poros, Spetses), and North Aegean islands. A dozen or so departure gates are spread along a long quay — check your e-ticket or the departure board for your gate on arrival, as gates change by season and by sailing.
Getting there: Metro Line 1 (Green) direct from central Athens (Monastiraki, Omonia) to Piraeus station — 30–40 minutes, €1.40. From Athens airport, take the metro to Monastiraki and change to Line 1 (the airport ticket is €9) or the X96 express bus (€5.50). Taxi from central Athens: 20–40 minutes, €20–30 (traffic-dependent). Uber works from Athens.
It's why I lock in summer crossings weeks ahead — pull up current routes and fares on Ferryscanner before the popular sailings sell out.
Rafina (Ραφήνα)
Secondary port, 30km northeast of Athens, 30 minutes from the airport by KTEL bus (€3.50, runs hourly). Serves ferries to: Andros, Tinos, Mykonos, and in summer, Paros, Naxos, Ios, and Santorini.
Use Rafina if: your first island is Mykonos, you're arriving at Athens airport, or you want to avoid the Piraeus chaos. Tickets from Rafina to Mykonos are often €10–15 cheaper than Piraeus, and the port is substantially smaller and easier to navigate.
Lavrio (Λαύριο)
Smaller port south of Athens, near Cape Sounion. Serves ferries year-round to Kea and Kythnos, and in summer, occasional services to Syros, Paros, Naxos, Folegandros, Milos, and Sifnos. Rarely used by international visitors but worth knowing for the western Cyclades without going to Piraeus.
Lavrio is the port most visitors never consider, and it is the reason Kea and Kythnos stay quiet — Kythnos is only about ninety minutes from there, against three to four hours from Piraeus. If you are looking for a Cycladic island you can reach in a morning, our Kythnos travel guide covers the Lavrio crossing and how to reach the port from central Athens.
The Ionian Islands Run on a Separate Network
Ferries to the Ionian islands do not leave from Athens. Corfu is reached from Igoumenitsa in about 1.5 hours, Zakynthos from Kyllini on the Peloponnese west coast in about 1.5 hours, and Kefalonia and Ithaca from Kyllini and Patras, so the Ionian network connects to the mainland rather than to the Cyclades. Our Ionian Islands guide covers all seven islands, and the Italy crossings below land on the same coast.
Ferry Types: The Decision That Matters Most
Not all Greek ferries are the same experience. Understanding the two main types prevents the most common tourist complaint about Greek ferries.
Blue Star Ferries (Conventional / Large Ferries)
Blue Star operates the large, conventional car-and-passenger ferries on the Cyclades, Dodecanese, and Crete routes. These are the right choice for most travelers.
What they offer: Open upper decks for fresh air and Aegean views. Indoor lounges with airline-style seats, bar and restaurant, sometimes a small shop. Smooth ride on most days — the large hull handles Aegean chop well. Can carry vehicles. Overnight cabin options (2-berth and 4-berth) on longer routes.
Honest downsides: Slower than catamarans. Piraeus to Santorini takes 8 hours on a conventional Blue Star (vs 4.5 hours on a fast ferry). The air-conditioned indoor lounges can feel stuffy. Some passengers find the overnight noise from the engine and other passengers disruptive.
Best for: Families, anyone prone to seasickness, travelers who want the deck experience, overnight routes, anyone traveling with a car or motorbike.
SeaJets and Other High-Speed Catamarans
SeaJets, Hellenic Seaways, and Fast Ferries operate high-speed catamarans on many Cyclades routes. They are faster — often half the time of conventional ferries — but the trade-offs are significant.
What they offer: Speed. Piraeus to Santorini in 4.5–5 hours vs 8 hours. Piraeus to Mykonos in 2.5 hours vs 5 hours. More departures in summer.
Honest downsides: Passengers are seated indoors throughout the journey — no outdoor deck access. The smaller hull means every wave is felt. In Meltemi wind conditions (common in the Cyclades July-August), a SeaJets catamaran is substantially rougher than a Blue Star ferry. Delays are more common when seas are rough, because some catamarans cannot operate above a certain wave height. They are also 15–30% more expensive.
Best for: Short routes (under 2 hours) where speed matters and the sea is calm. Naxos to Santorini (1.5 hours), Paros to Mykonos (1 hour). Less appropriate for longer runs in summer.
The rule: If both Blue Star and SeaJets serve your route, choose Blue Star for anything over 2 hours and for any July-August travel in the Cyclades. Take the fast ferry for short inter-island hops and in shoulder season when the Meltemi is absent.
Hellenic Seaways Flying Dolphins
Hydrofoils operating primarily in the Saronic Gulf (Athens-Aegina-Hydra-Poros-Spetses). Fast and efficient for Saronic island day trips. Very affected by rough seas.
Ferry Times From Athens to the Most Popular Islands
Most visitors search for the same handful of crossings. These are typical sailing times, fast ferry first and conventional ferry second, from Piraeus unless noted, and they match the route table at the top of this guide. Times stretch when a conventional ferry makes extra island stops.
- Athens to Santorini: 4.5–5 hours by fast ferry, about 8 hours by conventional Blue Star. This is the most booked route in Greece, so reserve early in summer.
- Athens to Mykonos: about 2.5 hours by fast ferry and 5 hours by conventional ferry from Piraeus. From Rafina the fast ferry takes 2.5–3 hours and is often cheaper.
- Athens to Naxos: 3.5–4 hours fast, about 5.5 hours conventional.
- Athens to Paros: 3–3.5 hours fast, about 5 hours conventional.
- Athens to Milos: about 3.5 hours fast, about 7 hours conventional.
- Athens to Crete: overnight only from Piraeus, around 9 hours to Heraklion. The Night Ferries section below covers seats and cabins.
- Athens to Rhodes: 14–16 hours overnight on Blue Star, long enough that many travelers fly instead.
- Santorini to Naxos: about 1.5 hours direct by fast ferry, the cheapest Santorini hop.
- Santorini to Mykonos: about 2.5 hours by fast ferry.
- Naxos to Paros: 30–45 minutes, the shortest hop on this list.
Operators and fares change by season, and published times are for the scheduled sailing rather than the delay-prone reality on multi-stop routes. Check the exact time for your date on a booking platform before you plan any connection.
Sikinos has only a few sailings a week from Piraeus, so plan around the timetable. Our Sikinos ferry and travel guide has the details.
How to Book Greek Ferry Tickets
Ferryscanner and Ferryhopper both cover all the major companies, display multi-leg routes in one search, and show live availability and pricing. Check the same route on two platforms before you buy, because coverage and prices differ slightly. Both work as apps and allow mobile boarding passes (a QR code on your phone — standard on most modern Greek ferries).
Direct ferry company websites also work — BlueStarFerries.com and SeaJets.gr both have online booking with e-tickets.
At the port: Ticket kiosks at Piraeus and other ports sell tickets for immediate sailings. In summer, don't count on finding seats for popular routes at the last minute.
What to book in advance:
- Piraeus/Rafina to Santorini, Mykonos, Naxos (July-August): 4–6 weeks ahead
- Overnight cabins on Piraeus-Crete or Piraeus-Rhodes: 2–3 months ahead for August
- Most other Cyclades routes (May-June, September-October): 1–2 weeks ahead is usually fine
- Saronic islands (Aegina, Hydra): walkup tickets are usually available
No unlimited Greek ferry pass exists. You will occasionally see "island hopping passes" marketed online — these are packages of individual tickets bundled by tour operators, not a single pass, and each leg of your journey still needs its own ticket. The one real rail-style pass is the Eurail Greek Islands Pass (Interrail for European residents), which covers a limited number of travel days on set routes within a month. It only pays off on a tight, route-matched itinerary, so check the current price and routes on eurail.com or interrail.eu before relying on it.
Ferry Seat Classes and Cabins
Most ferries sell several classes. Economy (deck) tickets are the cheapest and give you the open decks and the general lounges, while an assigned airline-style seat in a quieter lounge costs a little more and is worth it on crossings over four hours in summer, when the general lounge fills up.
Many Blue Star ships also sell a business class lounge, and overnight routes sell 2-berth and 4-berth cabins. Fast ferries follow the same logic: an economy seat is fine on a half-empty off-season crossing, but upgraded seating with more legroom is worth considering on a long peak-season route. If you are travelling in July or August and want a guaranteed place to sit, buy the assigned seat rather than the cheapest ticket.
Navigating Piraeus Port
Piraeus is large, disorganized by first impression, and entirely manageable once you know the gate system.
Gate assignments run from E1 to E12 along the quay and change with the season and the operator, so confirm yours on your ticket rather than relying on a fixed list. In general, the Saronic boats, the fast Cyclades ferries and the large conventional ships to Crete, Rhodes and the rest of the Dodecanese leave from different stretches of the quay.
Arrival logistics:
- Allow 30–45 minutes before departure
- The metro station drops you near the E5–E6 gates, and a gate at either end of the quay can be a 15–20 minute walk, so leave extra time if you have luggage
- The departure board at the main port entrance shows gates and times
- Ask at the port authority kiosk if you can't find your ship
Boarding: When boarding is called, passengers gather near the ramp. Staff scan QR codes from phones — keep your phone unlocked and ready. Large luggage is usually directed to storage on the car deck; keep valuables, medication, and documents with you.
Night Ferries: The Underused Strategy
The overnight ferry is one of the best value moves in Greek travel and is significantly underused by international visitors.
The same applies if you're arriving from Italy: the Adriatic ferries from Bari, Brindisi and Ancona to Igoumenitsa and Patras run overnight too, and our Italy and Greece cruise guide compares them with the cruise options.
If you are heading on to Croatia, there is no regular direct ferry; a cruise between Greece and Croatia is the simplest way to cover Dubrovnik and the Greek islands in one trip.
How it works: Depart Piraeus around 9–10pm. Sleep in a cabin (2-berth or 4-berth, book ahead) or in a reclining seat. Arrive at your destination at dawn, ready for a full day without burning a hotel night.
Best overnight routes:
- Piraeus → Heraklion (Crete): departs ~9pm, arrives 6am — saves one accommodation night, costs €60–90 per person with a 2-berth cabin
- Piraeus → Rhodes: departs ~9pm, arrives late morning next day — very long but efficient for Rhodes as a base
- Piraeus → Chania (Crete): arrives at Souda, Crete's western port, closer to Chania
Athens to Crete by Ferry
Crete is the one big island you reach from Athens by overnight ferry rather than by fast catamaran. Ships leave Piraeus in the evening for Heraklion on Crete's central north coast and for Chania, landing at Souda port in the west, and the Heraklion run arrives around dawn after roughly nine hours, so you save a hotel night. Expect to pay about €35–55 for a seat or €60–90 for a cabin berth, and book cabins early for August.
If you are already in the Cyclades, summer fast ferries connect Santorini with Heraklion in about two hours, which is the quickest way to add Crete to an island-hopping route. For a Crete-only trip, compare the ferry with a flight, and see our Crete travel guide for where to base yourself.
Cabin classes: Basic 4-berth cabin is adequate for budget travelers. The 2-berth cabin (with a small window, two proper bunks) is worth the upgrade for couples. Some ferries have Business Class cabins with better facilities.
Good to know: Bring earplugs. The engine noise is continuous, and other passengers in shared cabins may not observe quiet hours. The ferry restaurant serves adequate food at reasonable prices.
Ferries From Italy to Greece
Ferries from Italy land on Greece's west coast, not in the islands most people came to see. The overnight Adriatic crossings run from Bari, Brindisi, Ancona and Venice to Igoumenitsa and Patras, with a summer-only Brindisi to Corfu service, and there is no direct sailing from Italy to the Cyclades.
Bari to Igoumenitsa takes about 12 hours on the overnight sailing, Brindisi to Corfu about 8 hours in summer, and Venice to Patras around a day and a half, so plan your first night around the length of the journey. Cabins sell out in July and August, and you can bring a car if you book the vehicle space.
From Patras, Athens is about 2.5 to 3 hours away by road or KTEL bus, which makes it the easier landing if Athens or the Cyclades are next. Igoumenitsa is closer to six hours from Athens but is the gateway to Corfu, Epirus and northern Greece; our Corfu travel guide covers what to do once you arrive.
Heading east rather than west? Short ferries link Samos, Kos and Rhodes with towns on the Turkish coast, and our Greece and Turkey cruise guide explains when a cruise that combines Greek islands with Ephesus and Istanbul is the better choice.
Seasickness: Honest Assessment
The Aegean Sea is genuinely rougher than many travelers expect — not because Greek ferries are bad, but because the Meltemi (a seasonal north wind) blows consistently through the Cyclades in July and August, creating 1–3 meter swells on many routes.
Who is at risk: Anyone who gets seasick in moderate-to-rough conditions should prepare for Greek ferries. The Cyclades routes are the most exposed. Crete routes are longer but often calmer.
Reduce risk:
- Choose Blue Star conventional ferries over high-speed catamarans for rough weather routes
- Sit near the center of the ship on the lowest accessible passenger deck — less movement
- Take seasickness medication (Dramamine/Stugeron) 1 hour before boarding if you're susceptible
- Fresh air on deck helps significantly — most conventional ferries have outdoor areas
- Avoid eating a heavy meal immediately before a rough-weather crossing
Rough season: July-August, particularly afternoon departures in the Cyclades when the Meltemi peaks. Morning crossings are generally calmer. Shoulder season (May-June, September-October) is significantly less rough.
Ferry Season and Winter Travel
Full service (June–September): All routes operate, multiple daily departures on major routes, high-speed catamarans running.
Shoulder season (April–May, October): Most major routes still run but with reduced frequency. High-speed services may run less often or be consolidated. Planning flexibility is important — check schedules on Ferryhopper before booking accommodation.
Winter (November–March): Limited service. Most islands receive at least one or two ferry services per week year-round (as ferries serve the islanders themselves, not just tourists), but schedules are thin, delays due to bad weather are common, and many high-speed services stop entirely. Winter ferry travel in the Cyclades requires planning flexibility and backup options.
Once you know how the ferries work, our guide to the best Greek islands to visit helps you decide which ones to sail to.
Practical Tips
Large luggage: On most large ferries, oversized bags are stored on the car deck — they are accessible before arrival. Keep a day bag with everything you need for the crossing (water, snacks, phone charger, medication, documents).
Vehicles: Conventional ferries (Blue Star, Minoan Lines) carry cars and motorbikes. Book vehicle space well in advance for July-August. Your car will be last on, first off — follow the crew's instructions on the car deck.
Strikes: Greek ferry workers strike occasionally, usually announced 24–48 hours ahead, and 1 May is a regular strike day. Strikes cancel all ferry services. If you have a ferry-dependent connection to a flight, allow buffer time or have a flight option as backup.
Arriving late or with heavy bags? Welcome Pickups offers fixed-price private transfers in Athens, including from Piraeus port, which can be easier than the metro with luggage.
Delays: Conventional ferries, especially on multi-stop Cyclades routes, accumulate delays at each island. A ferry that departs Piraeus on time may arrive at Santorini (its fifth stop) 1.5 hours late. Fast catamarans are more punctual but cancel entirely in rough weather. Build arrival buffer time before important connections.
What Happens If Your Ferry Is Cancelled
Cancellations are weather or strike driven. Fast catamarans stop sailing in lower winds than the large conventional ferries, so on a bad Meltemi day the Blue Star sailing is usually the one still running, and sailings generally stop at around force 8 on the Beaufort scale. If a sailing is cancelled, the operator must offer you either a refund or a seat on the next available sailing under EU maritime passenger rights, and booking platforms usually notify you by email or in the app.
In practice, everyone shifts to the next day's sailing, which fills up fast. Keep your accommodation flexible on the island you are leaving, build a spare day in before any flight home, and follow your ship live on MarineTraffic or MyShipTracking. The days around Orthodox Easter and 15 August are among the busiest of the year, so book those sailings early.
Staying connected: Non-EU visitors can face high roaming charges on Greek networks, so set up an eSIM before you fly. Our guide to the best eSIMs for Greece compares the options.
Greece Ferry FAQ
Do I need to book Greek ferries in advance?
For July and August on popular routes (Piraeus to Santorini, Mykonos, Naxos), yes: book 4–6 weeks ahead, and overnight cabin berths for August sell out 2–3 months ahead. In shoulder season (May–June, September–October) most routes have availability a week or two out. For the Saronic islands (Aegina, Hydra, Poros), walk-up tickets are usually available.
Are Greek ferries safe?
Yes. Greek ferries operate under strict EU maritime safety rules and are generally reliable and well maintained. The main issues are comfort (rough seas on some routes) and timing (delays are common on multi-stop routes), not safety. Cancellations because of extreme weather are a real possibility in autumn and winter and less so in summer.
What is the best ferry company in Greece?
Blue Star Ferries for the large conventional ferries on the main Cyclades, Dodecanese and Crete routes, which are the most reliable and the most comfortable in rough water. For speed on short hops, SeaJets and Hellenic Seaways catamarans are the usual choice, and Golden Star runs fast boats from Rafina to Mykonos. The sensible rule is Blue Star for anything over two hours in July and August, and a fast ferry for short crossings in calm weather.
How long is the ferry from Athens to Santorini?
4.5–5 hours by fast ferry and about 8 hours by conventional ferry, both from Piraeus. The conventional ferry is cheaper, smoother in rough weather and has outdoor decks, so it suits most travelers. The fast ferry is worth it when time is tight.
Can I take a ferry between any two Greek islands?
Not directly. The Greek ferry network is hub-and-spoke, not fully connected. Most routes go through Piraeus or through a major island hub (Paros, Naxos, Mykonos, Rhodes), and some island pairs require routing back through Athens. Stay within one island group (Cyclades, Dodecanese, Ionian) and route within it; crossing between groups usually means flying or a very long ferry via Piraeus.
Is flying better than the ferry between Greek islands?
For short inter-island routes (Santorini to Naxos, Paros to Mykonos), the ferry is faster door to dock than flying once airport transfers and check-in are included. For long routes (Athens to Rhodes, or Athens to Crete when time is tight), flying is faster and sometimes similarly priced. For anything under 3 hours by fast ferry, take the ferry; for routes over 5 hours where time is tight, compare flights.
Do I need a passport or ID on a Greek ferry?
Boarding on domestic routes is normally by QR code with no ID check, but carry your passport or ID card anyway, because operators and the port police are entitled to ask for it. Sailings to Turkey or Italy are border crossings, and you will need your passport.
How early should I arrive at the ferry port?
Arrive 30–45 minutes before departure. In Piraeus, allow extra time if your gate is at the far end of the quay, and have your QR code ready on your phone when boarding is called.
What happens if my ferry is cancelled?
The operator must offer you a refund or a seat on the next available sailing. Fast catamarans cancel in lower winds than the large conventional ferries, so a Blue Star sailing is often still running when the fast ferry is not. Keep your accommodation and any flight home flexible by a day.
Can I take a ferry from Greece to Turkey?
Yes, on seasonal routes that link the eastern Aegean islands with the Turkish coast, for example Kos to Bodrum, Rhodes to Marmaris, Samos to Kuşadası, Chios to Çeşme and Lesbos to Ayvalık. These are border crossings, so you need your passport, and some routes run only in summer, so check the current schedule with the operator.
Is there a ferry pass for Greece?
No unlimited pass exists. The Eurail Greek Islands Pass (Interrail for European residents) covers a limited number of travel days on set routes and only pays off on a tight itinerary, so price your actual route ticket by ticket first.
How much do ferries in Greece cost?
Short island hops cost roughly €12–40, fast ferries from Piraeus to the main Cyclades are about €45–75 in peak season, and an overnight crossing to Crete costs about €35–55 for a seat, plus more for a cabin. Fast ferries cost 15–30% more than conventional ones. These are approximate peak-season figures, so check your date on a booking platform.
Where can I find the Greek ferry schedule?
Booking platforms such as Ferryscanner and Ferryhopper list sailings as the operators publish them, usually a few months ahead, and a route that does not show yet has often just not been released. Check the operators' own sites (BlueStarFerries.com, SeaJets.gr) too, and expect a thinner timetable from November to March.
