Where do ferries to Greek islands depart from Athens?

Almost all Greek island ferries depart from Piraeus port, approximately 10km southwest of Athens city centre. Metro Line 1 (Green Line) runs directly to Piraeus station, which is a 5-minute walk from the port gates. Allow 45–60 minutes from central Athens including the metro journey.

How early should I arrive at the port for a ferry?

For large conventional ferries (Blue Star, ANEK), arrive 45–60 minutes before departure. For high-speed catamarans, 30 minutes minimum. For vehicle loading, arrive 90–120 minutes early to secure your car position. Piraeus is chaotic in summer — factor in extra time.

Can I just turn up and buy a ferry ticket on the day?

In shoulder season (May, June, September, October) this often works on less popular routes. In July and August, popular routes (Piraeus–Santorini, Piraeus–Mykonos) sell out. Overnight cabins sell out earliest. Book in advance or risk a difficult deck crossing.

What is a ferry cabin and should I book one?

Cabins are small sleeping berths (2–4 beds) available on large overnight ferries. They cost significantly more than a deck or airline-style seat but are worth it on journeys of 8+ hours. A 4-berth cabin is more economical than a 2-berth and you'll often have it to yourself outside peak season.

What should I do if my ferry is cancelled?

Contact the ferry operator immediately to rebook on the next available service — operators typically transfer you at no extra cost. If weather-related cancellations strand you, accommodation options on smaller islands can fill up quickly, so act fast. Travel insurance covering weather delays is highly recommended.

Is it safe to travel by Greek ferry?

Modern Greek ferries are subject to EU maritime safety regulations and are well-maintained. The Greek coast guard is active. The practical risks are seasickness on exposed routes in rough conditions, and the practical inconvenience of cancellations rather than any safety concern.

Booking Your Greek Ferry Ticket

Book overnight cabins and peak summer tickets 2–4 weeks ahead. Day tickets and shoulder-season sailings can often be purchased 1–2 days before. Bring your booking confirmation to the port — most operators issue e-tickets or PDF confirmations. Some routes still use physical tickets collected at port kiosks, so arrive 45–60 minutes before your scheduled departure at major ports like Piraeus.

Piraeus Port — How to Navigate It

Piraeus is Greece's main ferry hub and one of the busiest ports in the Mediterranean. It can be confusing: gates E1 through E12 serve different destinations, and they are spread over a significant distance. Blue Star Ferries to the Cyclades and Dodecanese typically depart from gates E2–E3. High-speed catamarans (SeaJets, Hellenic Seaways) often depart from E9–E10 or the outer arms. Check your ticket for the specific gate — and walk there, do not assume it is nearby.

Deck vs Cabin — Which to Choose?

For overnight crossings of 8 hours or more (Piraeus to Rhodes, Piraeus to Kos, Piraeus to Patmos), a cabin is strongly recommended. Deck seating on overnight ferries is functional but can be uncomfortable for a full night — air conditioning on ferries is often set very cold, and deck chairs are basic. Cabin grades range from airline-style reclining seats (cheapest, better than deck) to 4-berth, 2-berth, and ensuite cabins. Book early for 2-berth cabins in summer.

Seasickness — What to Know

The Aegean can be rough, particularly from July to September during the Meltemi. On a calm day (Beaufort 0–3) even the smallest catamaran is smooth. At Beaufort 5–6, the same vessel can be extremely uncomfortable for non-sailors. Large Blue Star overnight ferries are more stable than high-speed craft at all sea states. If you are susceptible: take medication (cyclizine, scopolamine patch) before boarding rather than after — it is much more effective when taken in advance. Stay on the outer deck in fresh air rather than in a sealed cabin if conditions are rough.

What to Bring on a Greek Ferry

Passport or ID — required for boarding on all routes
Seasickness medication and a water bottle
A light jacket — ferry air conditioning is often cold
Food and snacks — onboard cafeterias exist but are expensive
An offline map of your destination port — phone signal can be patchy
Your ticket or e-ticket confirmation

Check the Teleporio Score the morning of any crossing — the Score accounts for your specific vessel type, departure time, and the forecast sea conditions, giving a single reliable number to assess before heading to the port. A Score below 60 is a signal to review your alternatives before committing to the gate; a Score above 80 means conditions are working in your favour.

Bring the Advice to Your Own Route

Use the route search for your actual ports and date, then read the current conditions alongside the timetable. General ferry advice is most useful once it is connected to the crossing you are about to make.
