Athens to Greek Islands by Ferry (2026 Guide)

By DiChatz

To ferry from Athens to the Greek islands, take Metro Line 3 to Piraeus (€1.20 from the centre, €9 from the airport), and book through one search site so you can compare Blue Star, Seajets and Fast Ferries on the same route. For anything within about four hours (Aegina, Poros, Hydra, Paros, Naxos, Mykonos) the ferry beats flying every time: no airport queues, sea views the whole way, and often faster door to door. For distant Rhodes, Kos or Crete, weigh a flight.

The single most important decision is which port you leave from, because Athens has three and they serve different islands. Get that right and everything else falls into place. Below is the practical playbook I give friends who land in Athens and want to be on a beach the same day.

Which Athens port for which island

Athens is served by three ferry ports, and turning up at the wrong one is the classic first-timer mistake. Piraeus is the giant that covers almost everything. Rafina and Lavrio are smaller, northeast and southeast of the city, and they cut travel time to a handful of specific islands.

Port	Islands it serves	Getting there from central Athens
Piraeus	Saronic (Aegina, Poros, Hydra, Spetses), most Cyclades (Santorini, Paros, Naxos, Mykonos, Milos, Syros, Sifnos), Dodecanese (Rhodes, Kos, Patmos, Kalymnos), Crete (Heraklion, Chania)	Metro Line 3 from Syntagma or Monastiraki to Dimotiko Theatro, €1.20
Rafina	Mykonos, Tinos, Andros, some Paros/Naxos crossings (often faster than Piraeus)	KTEL Attikis bus from Athens (about 1 hour)
Lavrio	Kea, Kythnos and northern Cyclades	KTEL Attikis bus (about 1.5 hours)

A note that saves confusion at Piraeus: the metro drops you near Gate E5/E6, but Seajets high-speed vessels usually leave from Gate E9, a 15 to 20 minute walk. The port is huge, so check your gate number on the ticket and give yourself the buffer. Free shuttle buses loop the gates if you are running short. For the Rafina and Lavrio buses, use the official KTEL Attikis site; those are public buses, not something you book on a ferry site.

If you are still deciding which island suits a short trip, my Best Day Trips from Athens guide and the Saronic-focused Hydra, Aegina and Poros ferry post pair well with this one.

Getting from the airport to the port

Landing at Athens Airport and heading straight for a ferry is very doable. Here are the real options and costs so you can plan the connection.

• Metro Line 3 (Blue Line), airport to Piraeus: €9, direct since October 2022, roughly 60 minutes. Best value by far, and it drops you right at the port.
• X96 express bus, airport to Piraeus: €6.40, runs 24 hours, cheaper but slower (about 90 minutes) and less predictable in traffic.
• Taxi: convenient with luggage but expect roughly €50 to €70 depending on time and traffic.

Build in a real cushion here. If your ferry leaves at, say, 7:25am, do not cut the airport metro fine; missing a high-speed departure can mean waiting hours for the next. If you would rather have a car waiting on the island instead of dragging bags onto a ferry, some travellers rent from the airport and drive to Piraeus, though most day-trippers and island-hoppers skip this. If you do want wheels, compare Athens car rental prices on Discover Cars.

The first thing I tell anyone taking a ferry from Athens: check which port before you check the timetable. Piraeus is the big one, but for Andros, Tinos and often Mykonos, Rafina is closer to the airport and a calmer place to start. At Piraeus, the gates are a long way apart and the boats do not wait, so be there an hour early and read the gate number on your ticket, not the one you assume. My own rule is the slow morning ferry whenever the crossing is under five hours: it is cheaper, it has open deck space, and it does not toss you around when the meltemi blows in August the way the fast catamarans do. Book ahead in July and August and whenever you are taking a car; the rest of the year I buy a day or two before and have never missed a sailing.

Routes, prices and travel times (2026)

The big choice on most routes is conventional versus high-speed. Conventional ferries are cheaper, steadier in wind, carry vehicles, and often run overnight with cabins (€60 to €150). High-speed catamarans halve the journey but cost more and cancel more readily in strong meltemi winds. Here is how the popular routes stack up.

Route	Time	From (2026)	Notes
Piraeus – Aegina (Saronic)	~40 min fast / ~70 min conv.	~€15	Closest island, frequent daily
Piraeus – Poros (Saronic)	~1 hr high-speed	~€34	Great half-day trip
Lavrio – Kea	~1 hr	€11.50–14	Cheapest island escape
Piraeus – Paros / Naxos	4–6 hr conv. / 3–4 hr fast	€25–45 / €40–65	All year, frequent in summer
Piraeus / Rafina – Mykonos	5–6 hr conv. / 3–4 hr fast	€35–55 / €50–80	Rafina often faster
Piraeus – Santorini	5–11 hr	from €46.50	Up to 8 daily in summer
Piraeus – Rhodes	overnight	from €46	1–2 daily, Blue Star
Piraeus – Kos	long haul	from €63	1 daily

I book everything through one search so I can compare operators (Blue Star, Seajets, Fast Ferries and others) on the same route in one place. Check live ferry schedules and prices on Ferryscanner.

Booking timeline matters. For June through September, and especially for a cabin or a vehicle space, book two to three months ahead. Peak weekends and the weeks around 15 August (a major Greek holiday) sell out first. Deck seats on conventional ferries are usually fine to grab closer, but high-speed routes to Santorini and Mykonos vanish fast on peak weekends.

Best short trips: Saronic and close Cyclades

If you only have a day, the Saronic islands are made for you. From Piraeus you can reach Aegina in around 40 minutes by fast boat, Poros in about an hour, and Hydra, which bans cars and is my personal favourite for a day out, in roughly 90 minutes. A 7am departure and a late-afternoon return gives you a genuine island day without an overnight: aim for a boat back around 5 or 6pm so you are not stranded if the last one is busy.

For a slightly bigger adventure, Paros and Naxos are the sweet spot in the Cyclades: reachable in three to four hours by high-speed, well connected, and good bases for hopping onward. Milos and Sifnos are quieter, wilder alternatives if you would rather trade nightlife for empty coves.

Prefer to leave the logistics to someone else? A guided island cruise handles the boat, timing and often lunch. Book a Saronic islands day cruise from Athens. You can also browse other Athens island day trips on GetYourGuide if you want to compare formats.

Strike and season warnings (read this)

This is the part most guides skip. Greek maritime unions call several nationwide ferry strikes every year, usually 24-hour stoppages announced only one to three weeks ahead, and they ground almost every boat for the day. In 2026 alone there were stoppages in late February, early March, on 1 May and in early July. The pattern is consistent: May Day is a near certainty, and the rest cluster around wage negotiations, so treat any single travel day as at risk rather than any particular date.

How I mitigate it: I never put my only travel day on a rumoured strike date, I keep the operator’s app or website open in the week before, and where possible I leave a buffer day rather than connecting a strike-risk ferry to a same-day flight home. If a strike is announced after you book, operators reschedule or refund, so watch your email.

Two more housekeeping tips: grab a data plan so you can check live departure boards and cancellations on the move (an Airalo eSIM works the moment you land), and if you are hopping multiple islands, EKTA travel insurance covers the odd missed-connection headache.

Frequently asked questions

Which Greek islands can you ferry to from Athens?

From Athens you can reach the Saronic islands (Aegina, Poros, Hydra, Spetses), most of the Cyclades (Santorini, Mykonos, Paros, Naxos, Milos, Syros, Sifnos, Tinos), the Dodecanese (Rhodes, Kos, Patmos, Kalymnos), and Crete (Heraklion, Chania). Piraeus covers almost all of them, while Rafina and Lavrio serve specific islands like Mykonos, Tinos, Andros and Kea faster.

What ferries can I take from Athens to the Greek islands?

The main operators are Blue Star Ferries, Seajets and Fast Ferries for the Cyclades and Santorini, with Blue Star also serving the Dodecanese (Rhodes, Kos, Patmos). Conventional ferries are cheaper and steadier; high-speed catamarans are faster but pricier and more prone to weather cancellations.

What is the best way to travel to the Greek islands from Athens?

For islands within about four hours, the ferry is usually the best option: no airport hassle, great views and frequent summer sailings. Take Metro Line 3 to Piraeus (€1.20 from central Athens, €9 from the airport), and book high-speed routes to Santorini or Mykonos two to three months ahead in peak season.

Is it better to fly or take a ferry from Athens to Crete?

For Crete specifically, flying often wins on time since the ferry is a long overnight haul. But the overnight ferry with a cabin lets you save a hotel night and arrive rested. If budget and comfort matter more than speed, the ferry is a solid choice; if you want to maximise island time, fly.
