How to Get to Ios: Ferries, Flights and Transfers From Athens

Ios has no airport, so getting there means taking a boat. Most visitors fly into Athens, ride to the port of Piraeus and sail from there. Others fly to Santorini, which has the closest international airport, and hop across. The decision that shapes your day is the ship. A fast catamaran gets you a beach afternoon on arrival. A big conventional ferry gives you room to roam and a lower fare.

How do you get to Ios from Athens?

Ferries leave from Piraeus, Athens' main port, all year round, with departures 6 to 7 days a week. Three companies work the route. SeaJets runs high-speed catamarans, and Blue Star Ferries and Fast Ferries run large conventional ships. Fares run from about €39 to €254 (2026), depending on the ship and the type of seat.

Rafina, the smaller port closer to Athens International Airport, also has Ios sailings. There is roughly one a day, and it takes around 4.5 hours. Rafina makes sense if you want to board soon after landing. If you're staying in central Athens, Piraeus is the easy pick, since the metro takes you right to the harbor and more ferries to Ios leave from here.

High-speed ferry

The SeaJets catamarans run mainly from spring to autumn, and they sail daily at the summer peak. Catch the early boat and you're on Ios by lunchtime, with the afternoon free for the beach. That speed costs noticeably more than a seat on a conventional ship. Seating is airline style, with a VIP section at a higher price, and there's very little outdoor deck. Food on board can be limited, so bring snacks.

Conventional ferry

Blue Star and Fast Ferries sail large ships with lounges, open decks, cafeterias and cabins. The open decks are where you watch the Cyclades slide past. These ships take longer because they call at several islands on the way, and they usually cost less than the catamarans. In winter they carry the route on their own, since high-speed boats generally don't run in the depth of the season. Some winter days have just one ship, so check the exact sailing days before you fix your plans.

In summer, the evening Blue Star sailing can reach Ios after midnight, so a cabin is worth booking on that crossing.

How long is the ferry to Ios?

The crossing time depends on the ship, with the catamarans much quicker than the conventional ferries. Fast SeaJets sailings from Piraeus to Ios take about 4 hours 10 minutes, while conventional ferries take around 7 hours, so the length of your trip depends a lot on which boat you pick. The distance is about 119 nautical miles (about 136 miles, or 219.5 km), so either way it's a proper sea voyage.

Is it better to take the ferry or fly to Ios?

You can't fly all the way to Ios. The nearest airport is on Santorini, and from there a short ferry ride takes you to Ios. That route works well if Santorini is already on your list. For a straight Athens to Ios trip, though, it means two legs, two sets of tickets and a tighter chain of connections. Weather can delay ferries, so a day that depends on a flight and then a boat is the more fragile plan.

Here's how to choose:

• First trip, want speed: SeaJets from Piraeus on a morning sailing.
• Family with luggage: a Blue Star or Fast Ferries ship, with room to move, food on board and cabins if someone needs a nap. Children usually travel at a reduced fare, often half price, but check when you book.
• On a budget: a conventional ship on a quieter date, booked early.
• Combining islands: fly into Santorini or Mykonos and hop by boat.

How do you get to Piraeus?

Piraeus sits about 7.5 miles (12 km) south of central Athens and about 28 miles (45 km) from the airport. From the center, take the green Line 1 metro to its last stop, Piraeus. The ride is about 25 minutes from Monastiraki, and the station faces the harbor. From the airport, the blue metro line runs through in roughly an hour. Coming from downtown by taxi or bus, count on about 25 to 45 minutes, with traffic making the difference.

Ferries to the Cyclades usually leave from Gates E6 and E7. Berths can change, though, so trust your ticket and the port screens on the day. The port stretches a long way along the water, and a free shuttle bus circles it, which helps when your gate is far from the metro. Many travelers aim to reach the port about an hour ahead of departure, and closer to 90 minutes when a car is coming along.

How do you get to Ios from other islands?

Ios sits among Santorini, Paros and Naxos, so it slots easily into a Cyclades loop. Ferries also link it with Mykonos, Milos, Folegandros, Sikinos, Syros and Crete, and connections are frequent from May to September. Typical crossings:

• Naxos: from about 25 minutes
• Folegandros: from about 30 minutes
• Santorini: 20 to 50 minutes
• Paros: about an hour
• Mykonos: about 1 hour 25 minutes
• Milos: about 1 hour 40 minutes

Schedules change every year. Larger ferry companies tend to publish their new timetables around the end of December, and smaller ones follow between January and March. Check the dates before you build an itinerary around a single link.

Does the weather affect the ferry to Ios?

Yes, it can. The main culprit is the meltemi, the strong northerly wind of July and August. Rough seas in early spring and late fall can also disrupt the fast boats. Catamarans are the first to slow down or cancel, while the big conventional ships usually keep going. If a sailing is disrupted, the next boat may not be until another day, so if you have an international flight home, it helps to leave yourself a spare day.

How do you book ferries to Ios?

Ferryhopper, DirectFerries and the operators' own websites show current schedules and prices, and local ticket offices in Greece sell tickets too. For July and August, book at least a few weeks ahead, because sailings to Ios can sell out. In spring and autumn, about a week ahead is usually enough. The lowest fares tend to appear on quieter dates, and operators often release deep discounts three to six months in advance.

Cars travel for an extra fee. Pets travel free when you add them to your booking. There's no luggage check-in, so keep your bags to what you can manage yourself.

How do you get from the port to your hotel?

Boats dock at Ormos, also called Gialos, on the west coast. It's a small, easy port with places to eat, cash machines, car hire and public parking. Chora sits on the hill above it, about 1.2 miles (2 km) away. That's roughly a 5-minute drive or a 20-minute uphill walk, and the walk is a sweaty one with a suitcase in August.

Local buses link the port with Chora and with Mylopotas Beach, the resort area where most visitors stay. Mylopotas is about 10 minutes away by bus. Ticket machines stand at the port bus terminal and at the Far Out Beach Club stop on Mylopotas.

Taxis are few, and they disappear fast when two ships dock together. Many hotels run their own transfers, so ask about one when you book, and arrange one for any late-night arrival.

Getting around once you're there

A rental car is the best way to explore at your own pace, and you can rent an ATV from Costa's Moto Club near Mylopotas Beach. Buses also reach the main beaches, including Manganari on the south coast. If you drive, Greek law requires a valid U.S. driver's license, and insurance companies may require an international driver’s permit.S. State Department. Thieves target rental cars for passports, valuables and luggage, so don't leave them inside.

What should Americans know before traveling?

U.S. citizens can enter Greece without a visa for stays of up to 90 days, and a passport should have at least three months of validity beyond your planned departure date. Carry your passport or a photo ID at all times. The U.S. State Department rates Greece as generally safe, but petty crime is common in tourist areas and on public transportation, especially the metro, so keep your valuables close on the ride to Piraeus. Transportation strikes can halt public transit, taxis, seaports and airports. The day before you sail, check the news for strikes, your operator's updates and the wind forecast.
