The Greek ferry network covers over 500 routes and moves millions of passengers every summer. For most visitors doing any kind of island hopping, it is unavoidable — and once you understand the system, it is genuinely 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 complete practical guide: ports, ferry types, booking platforms, route times, what to do at Piraeus, night ferries, seasickness, and the specific things first-time visitors consistently wish they'd known.

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. 12 departure gates across a large quay — get to your gate early and check the board on arrival, as gates can change.
Getting there: Metro Line 1 (Green) direct from central Athens (Monastiraki, Omonia) to Piraeus station — 30–40 minutes, €1.40. 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.
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.
How to Book Greek Ferry Tickets
Ferryhopper is the best booking platform for Greek ferries. It covers all companies, displays multi-leg routes in one search, and shows real-time availability and pricing. The app works well and allows mobile boarding passes (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 Greek island 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. Each leg of your journey requires a separate ticket purchase.
Navigating Piraeus Port
Piraeus is large, disorganized by first impression, and entirely manageable once you know the gate system.
The 12 gates (E1–E12) are spread along the quay from east to west. Each serves different destinations:
- Gates E1–E2: Saronic islands (Aegina, Hydra, Poros, Spetses) — direct and fast
- Gates E6–E9: Main Cyclades fast ferries (Santorini, Mykonos, Naxos, Paros, Milos)
- Gates E10–E12: Large conventional ferries — Crete, Rhodes, and other Dodecanese
Arrival logistics:
- Allow 30–45 minutes before departure
- The metro station dumps you at Gate E1/E2 — most fast Cyclades ferries are a 10–15 minute walk along the quay
- 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.
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
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.
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.
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. 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.
For a stress-free arrival directly to Piraeus or Rafina port, book a private transfer with Welcome Pickups — fixed price, no surprises.
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.
Interrail Greece Ferry Pass: European residents can use an Interrail Greek Islands Pass — 4 domestic itineraries within one month for approximately €90. Useful for multi-island trips on specific Blue Star and Hellenic Seaways routes. Check current availability at interrail.eu.
Staying connected: Non-EU visitors face high roaming charges on Greek networks. Activate a Yesim eSIM before you fly — instant setup, no physical SIM, works the moment your plane lands in Athens.
