Which Athens port should I use for the Greek islands?

Piraeus handles the vast majority of Cyclades, Crete and Dodecanese routes. Rafina, near Athens airport, is the better choice for Mykonos, Tinos and Andros — it saves you the trip into the city centre.

How far in advance should I book Greek island ferries?

Book at least 2–4 weeks ahead in July and August, especially for car spaces and popular Cyclades routes. In shoulder season (May–June and September) a few days' notice is usually sufficient. Winter services are limited and timetables change.

What are meltemi winds and do they affect ferries?

The meltemi is a strong dry northerly that sweeps the Aegean from June to September, peaking in August. High-speed catamarans are cancelled or delayed first; large conventional ferries manage better. Build slack time into your itinerary during this period.

Can I take my car on Greek island ferries?

Yes on most main routes — Blue Star and other large conventional ferries carry vehicles. High-speed catamarans generally do not, or carry very few. Book car spaces as early as possible; they sell out well before passenger tickets.

Greek Island Hopping by Ferry: The Definitive Guide

Greek island hopping by ferry is one of the great travel experiences of the Mediterranean. The network is extensive, the scenery unmatchable, and with a little planning you can move island to island on your own schedule — no package tour required. This guide covers the departure ports, the main island groups, how to build a route, and the practical details that trip up first-timers.

Piraeus and Rafina: the Athens departure ports

Almost all island-hopping routes begin in Athens, and two ports serve the city.

Piraeus is the giant, with connections to virtually every destination in the Aegean. Metro line 1 from the city centre takes around 40 minutes. For Santorini ferries, Naxos ferries, Ios ferries, Crete and the Dodecanese, Piraeus is your port.

Rafina, 35 km north-east of the centre and close to Athens airport, is smaller but quicker for Mykonos ferries and Tinos ferries. If you are flying into Athens and heading straight to Mykonos, skipping the metro to Piraeus entirely can save you two hours.

Arrive at either port at least 45 minutes before departure. Piraeus is large and the gates can be spread across a long quayside — allow time to find the right berth.

The island groups

Greece has five main island chains, each with its own character and frequency of services.

The Cyclades

The Cyclades are the heart of Greek island hopping: a loose arc of islands in the central Aegean with some of the best ferry connections in the Mediterranean. Santorini and Mykonos are the busiest; Paros, Naxos, Ios and Milos are excellent quieter alternatives.

From Piraeus: the Athens to Santorini ferry takes roughly 5 hours by high-speed or 8 hours conventional. The Athens to Mykonos ferry is similar. Once in the Cyclades, you hop between islands quickly: Santorini to Mykonos is 2–3 hours; Mykonos to Paros about 45 minutes; Naxos to Ios 30–45 minutes by fast ferry.

Crete

Crete is the largest Greek island and best reached by overnight conventional ferry from Piraeus — the journey runs through the night so you arrive in Heraklion in the morning. The Athens to Crete ferry is the main link, operated by Minoan Lines, ANEK and Blue Star. From Crete you can continue into the Cyclades: Crete to Santorini is a popular onward leg.

The Dodecanese

Rhodes and Kos lie further east, close to the Turkish coast. The Athens to Rhodes ferry from Piraeus is a long overnight journey — 13 to 17 hours depending on the route and stops. Rhodes makes a good base for exploring Kos; the Kos to Rhodes ferry takes 2–3 hours.

The Saronic Islands

The Saronic islands — Aegina, Hydra, Poros — are easy day trips or short overnight escapes from Athens. Athens to Aegina is under an hour by hydrofoil, making it the most accessible island from the capital. Athens to Hydra is a beautiful car-free island reached in about 1.5 hours.

The Sporades

Skiathos and Skopelos are popular islands in the northern Aegean, reached from Volos or Agios Konstantinos on the mainland rather than from Piraeus. The Athens to Skiathos ferry runs from those northern ports and takes 1.5–2.5 hours by high-speed.

Sample routes

7-day Cyclades circuit

A week is enough to cover the core Cyclades without rushing.

Day 1–2: Athens — arrive, explore, take the metro to Piraeus
Day 2–3: Santorini — Athens to Santorini by high-speed (about 5 hours); caldera sunsets, Oia, Akrotiri
Day 3–4: Ios — Santorini to Ios takes under an hour; quieter beaches, good nightlife
Day 4–5: Naxos — Naxos to Ios reversed; the largest Cycladic island, great food and beaches
Day 5–6: Paros — Naxos to Paros is a short hop; pretty Parikia old town and Naoussa harbour
Day 6–7: Athens — Athens to Paros by fast ferry back to Piraeus in about 3 hours

10-day Cyclades and Milos

Add Milos ferries for its dramatic volcanic landscape and famous beaches.

Days 1–2: Athens
Days 2–4: Santorini
Day 4–5: Milos — from Santorini via Milos to Santorini route (reversed); or Athens to Milos direct from Piraeus
Days 5–7: Paros — from Milos by Seajets
Days 7–9: Mykonos — Mykonos to Paros reversed; Mykonos Town, Delos day trip
Day 9–10: Athens — Athens to Mykonos ferry from Mykonos back

14-day full Cyclades and Crete

A two-week trip lets you add Crete and the lesser-visited islands.

Days 1–2: Athens
Day 2–3: Heraklion (Crete) — Athens to Crete ferry overnight, arrive morning
Day 3–5: Santorini — Crete to Santorini high-speed catamaran
Day 5–7: Naxos — Santorini to Naxos; hike, swim, eat well
Day 7–8: Ios — Naxos to Ios; day of beach time
Day 8–10: Paros — Paros to Ios reversed; base for exploring both islands
Day 10–12: Mykonos — Mykonos to Paros reversed; Mykonos and Delos
Day 12–13: Tinos — Mykonos to Tinos is a short 15–30-minute crossing; serene, underrated
Day 13–14: Athens — ferry back from Tinos or Mykonos via Rafina

High-speed vs conventional ferries

High-speed catamarans (SeaJets, Hellenic Seaways Flying Cat) cut crossing times roughly in half but cost more, carry fewer vehicles and are more vulnerable to cancellation when winds pick up. They are ideal for foot passengers wanting speed.

Large conventional ferries (Blue Star, ANEK, Minoan) are slower but cheaper, comfortable for overnight crossings, and carry cars and motorcycles. They run even in moderate seas and are the backbone of the network.

On busy routes you will often have both options. For overnight journeys — Athens to Crete, Athens to Rhodes — the conventional ferry is almost always the right choice: you save a night's accommodation and arrive refreshed.

Meltemi winds: the essential seasonal fact

The meltemi is a persistent northerly that blows across the Aegean from roughly June to September, strongest in July and August and most intense in the central Cyclades. It can ground high-speed services for a full day or more with little warning.

If you are travelling in high summer, build at least one flexible day into your itinerary between each island, or choose the conventional ferry option which handles wind better. Morning departures tend to be more reliable than afternoon ones, when the meltemi often strengthens.

When to book

July–August: Book as early as possible — 4–6 weeks ahead for popular routes; immediately if you have a car. Santorini, Mykonos, Ios and Paros all sell out regularly.

June and September: 1–2 weeks ahead is usually enough for most routes, though popular weekend slots fill quickly. Car spaces still need advance booking.

Shoulder and off-season: Outside peak summer, book a few days ahead. Many high-speed services stop running after October; winter schedules reduce dramatically to one or two sailings per week on some routes.

The main booking platforms — Ferryhopper, Direct Ferries and the individual operator sites — all let you compare options and book months in advance.
