Ferry from Ios to Rafina is a popular way to travel from the Cyclades back to the Athens area, linking Ios port (Gialos) with Rafina, the second main port of Attica on the east coast. This route is mainly operated by Golden Star Ferries with high speed vessels and usually runs once per day in season, giving about 7 sailings per week. The crossing distance is roughly 103 to 104 nautical miles and typical journey times are around 5 hours, with the fastest sailings close to 4 hours 25 minutes. Rafina is only about 10 kilometres from Athens International Airport, so this Ios–Rafina ferry is especially useful for travellers with flights in or out of Athens.
Key Information
Ferry duration
The usual duration of the Ios to Rafina ferry is about 5 hours 5 minutes with Golden Star Ferries, according to recent schedule summaries. Different sources state that fastest crossings take around 4 hours 20 to 4 hours 25 minutes, while the average is around 4 hours 20 to 5 hours 5 minutes depending on the exact sailing.

Ferry companies
The Ios to Rafina line is currently served by Golden Star Ferries, which is listed as the sole operator on this direct route with 7 weekly sailings. Route overviews also mention that other major Aegean companies such as Blue Star Ferries, SeaJets and Fast Ferries run many Rafina–Cyclades routes, but for Ios–Rafina specifically the scheduled direct sailings are handled by Golden Star Ferries’ Super Express vessel. In practice this gives one afternoon departure each day in season, usually around 15:15 from Ios.
Fast vs slow ferry
On this route there is no slow conventional option dedicated only to Ios–Rafina, because Golden Star Ferries uses high speed ships, so differences are small rather than dramatic. The quoted fastest trips are around 4 hours 20–4 hours 25 minutes, while timetable averages put most crossings at about 5 hours 5 minutes depending on sea conditions. When choosing a sailing you mainly decide based on the day and whether the specific departure is non stop or includes extra island calls, rather than on a big speed difference.
Best time to travel
Ios–Rafina ferries are seasonal, with the main schedule running roughly from late spring to early autumn and the most reliable service in June, July, August and early September. One timetable summary notes 7 weekly Golden Star Ferries crossings, effectively one daily departure in high season. Outside these months you may find fewer or no direct Ios–Rafina sailings, so travelling via Piraeus or combining ferries becomes more common in shoulder and low season.
Sea conditions and wind
The open sea between Ios and Rafina can be affected by strong Meltemi winds in July and August, which may cause choppy conditions and lead to slightly longer journey times. High speed vessels are more sensitive to wind than large conventional ferries, so in very rough weather departure times can change or, more rarely, sailings can be cancelled for safety reasons. If you are prone to seasickness, consider choosing a seat near the middle of the ship and taking motion sickness tablets, especially in mid summer.
Port guide
In Ios, ferries to Rafina depart from the main port at Gialos, which has ticket offices, cafés, tavernas, minimarkets and car rental agencies within a short walk of the quay. In Rafina, the ferry arrives at the town’s main port, which lies about 0.6 miles from the centre, with bus connections, taxis and services linking directly to Athens International Airport and central Athens. Rafina is closer to the airport than Piraeus, so it is a convenient arrival point if you are flying the same or next day.
Car rental advice
Ios has plenty of car, quad and scooter rental outlets around Gialos and in Chora, so many visitors rent vehicles to explore the island and then return them before heading to the mainland. In Rafina you can either hire a car locally or travel by bus or taxi to the airport or Athens city, where there are many more rental options. Golden Star Ferries’ ships on this route can carry vehicles, but spaces are limited and summer demand is high, so you should book any car or motorbike tickets in advance and check in at least 1 hour before departure.
Foot passenger tips
As a foot passenger travelling from Ios to Rafina, aim to arrive at Ios port at least 30 to 45 minutes before departure, and earlier in July and August when ferries are busier. Operator guidance states that foot passengers must check in at least 30 minutes before departure, while vehicle passengers should check in at least 60 minutes before. Boarding can involve walking up ramps and using internal stairs, so lighter luggage and a small day bag with water and snacks make the journey more comfortable.
Is this route worth it?
The Ios to Rafina ferry is very worthwhile if you are flying into or out of Athens airport, or if you prefer a smaller, calmer mainland port than Piraeus. With journey times of about 4.5 to 5 hours and one daily high speed sailing, it offers a direct and efficient link between Ios and Attica. For travellers planning to visit Ios after exploring Andros, Tinos or Mykonos from Rafina, this route fits neatly into a wider Cyclades itinerary.
Alternative route if cancelled
If there is no suitable Ios–Rafina sailing on your date, the main alternative is to travel via Piraeus or Lavrio. Ios has frequent ferries to Piraeus and a weekly link to Lavrio, both of which connect with buses and taxis to Athens and the airport, so you can still reach Attica on the same or following day. Another option is to route through hub islands such as Mykonos or Naxos, which have multiple daily connections to Rafina in the high season.
Reverse route internal links
The reverse Rafina to Ios route is well documented and currently run solely by Golden Star Ferries with around 6 to 7 weekly high speed sailings. Typical crossing times for Rafina–Ios are about 4 hours 20 to 4 hours 25 minutes, with early morning departures around 07:20 from Rafina.
