Santorini to Naxos Ferry: How Long It Takes, What It Costs, Which Boat to Pick

Blue Star Ferries runs this crossing year-round, Seajets adds high-speed boats in the warmer months, and your choice comes down to time, price and how your stomach handles the sea.

Which ferry companies make the crossing?

Two operators carry most of the traffic. Blue Star runs large conventional ferries with a cafeteria, a restaurant, air-conditioned lounges and open decks. Seajets runs high-speed catamarans with numbered, airline-style seats, snack bars and very little deck space. A third company, Golden Star Ferries, sails the route occasionally, about once a week in some months, and is slower. It's worth checking when the main boats are full.

Boats link the two islands every day of the year. In summer, several departures a day are spread from morning into early evening. The high-speed boats run roughly March to October, so in winter plan around a single daily Blue Star sailing.

How long is the crossing?

The quickest Seajets catamarans make it in about 1 hour 10 minutes. Many of their runs take closer to an hour and a half, and some multi-stop sailings need as long as 2 hours 35 minutes. Blue Star normally takes about 2 hours, and a few of its itineraries run longer.

Stops explain most of the difference. Some boats go straight to Naxos, while others call at Ios first and then carry on north. Two boats leaving at similar times can have very different journey lengths, so check the full route before you buy.

Which boat is better: Blue Star or Seajets?

Blue Star is the steadier, cheaper choice. The ships are large, with open decks and room to walk around, eat and watch the caldera cliffs slide past. It suits families, anyone prone to seasickness, anyone who wants to be outside, and anyone traveling with a car. The catch is that its departure times may not fit your day.

Seajets earns its higher fare when it buys you real time. An early arrival in Naxos means you can check in, drop your bags and have most of an afternoon on the waterfront. The trade-offs are enclosed seating, less freedom to move, and a bumpier ride when the wind is up. If you're on a catamaran and worried about motion, sit near the middle of the boat, keep your eyes on the horizon instead of a phone or book, skip a heavy meal right before departure, and take any motion-sickness remedy ahead of time, following the package directions or your doctor's advice.

How much does the ferry cost?

Fares vary by date, vessel and demand. As a rule, a Seajets economy seat costs roughly twice as much as Blue Star's basic fare. Business and VIP seats on Seajets cost more again and buy a quieter lounge and extra space, which most travelers find unnecessary on a crossing this short.

Vehicles need their own ticket, and space is limited. Blue Star and most Seajets catamarans take cars, but some smaller high-speed boats do not. In peak summer, booking early helps you land the lower fares and a car space, since both islands are at full capacity in August. Child discounts depend on the company and the child's age, so enter the correct age for each passenger when booking.

When you compare prices, compare similar seat types. Setting the cheapest Blue Star ticket against a premium catamaran seat makes the gap look bigger than it is.

Where should you buy tickets?

Comparison sites are handy for seeing schedules, vessels and stops side by side. Buying direct from the ferry company gets you the freshest word if a sailing is changed or cancelled. Outside the peak months, a travel agent on Santorini works well too, and gives you the latest news on weather and strikes.

Timing depends on the season. If you want a specific departure, a premium seat or space for a car in July or August, reserve as soon as your travel dates are settled. In May, June, September and October, a few weeks ahead is usually enough, though it pays to book earlier when just one sailing suits your plans. In winter, seats rarely sell out.

You can get a boarding pass on your phone for the main ferries on this route. Follow the check-in instructions in your confirmation email, since some companies issue the pass right away and others ask you to check in online first. Save the pass or a screenshot before you leave your hotel, because signal can be shaky around the crowded port, and carry the ID you booked with. On Seajets, economy seats are assigned by the system, and a group may find its seats scattered around the cabin. You can move to free seats on board, though they may fill as the boat picks up passengers at later stops.

How does luggage work on the ferry?

Allowances are generous, and normal holiday suitcases aren't weighed. Large bags go in racks near the entrance, and those areas get crowded when a boat serves several islands, so label each one. Keep your passport, medication, electronics, cash and other valuables with you.

Can wind delay or cancel the ferry?

Yes, mostly in high summer. High-speed catamarans can be delayed or cancelled when the wind picks up, and the port authority may keep ships in harbor.

A cancelled ticket isn't lost. The operator moves you to another sailing or refunds you, and the daily Blue Star ship makes a handy fallback when a catamaran stays in port. Wind aside, boats that reach Santorini after earlier island stops run late more often, especially later in the day. For peak summer, build in a buffer day, favor morning sailings when the sea tends to be calmer, and don't book a tight rental-car pickup, tour, dinner or flight right after your scheduled arrival.

How do you get to the ferry port in Santorini?

Passenger ferries leave from Athinios, on the west coast about 5 miles (8 km) below Fira. Skip the Old Port under Fira, which handles cruise passengers and excursion boats. Athinios sits at the foot of the caldera cliffs, and a single steep road with hairpin bends links it to the rest of the island. That road jams when several ships are due, especially from June through September.

Port buses depart from the main bus station in Fira and follow the ferry timetable, so look up the current times shortly before your trip. The bus is cheap and works well if you're traveling light, but it gets crowded, and from Oia, Imerovigli, Kamari or Perissa you'll have to reach Fira first. From Oia or Imerovigli, leaving two hours or more before a busy summer sailing is reasonable, and your hotel or transfer company can suggest a pickup time. Rental cars can be returned at Athinios if you arrange it with the rental company in advance. Confirm the meeting point, since stopping space near the ramps is tight.

Aim to reach the port 45 to 60 minutes before departure, or about 90 minutes if you're driving on. Arriving much earlier buys you little. The port is small, crowded and exposed to sun and wind, with ticket offices, cafés and toilets but little indoor waiting space. Keep children close, wait near the cafés until boarding starts, and listen for announcements, because ferries load quickly.

What is the arrival in Naxos like?

As the boat pulls in, look north to spot the Portara on its little islet beside town. The ferry docks at the edge of Chora on the west coast, and the old town, waterfront cafés, bus station, taxi stand and many hotels are within walking distance. Your walk to the hotel may take you over cobbled lanes, up stairs or through car-free alleys, so check the exact location if your bags are heavy.

Beach areas such as Agios Prokopios, Agia Anna and Plaka are too far to walk. The KTEL bus station is a short walk from the pier along the harbor front, and buses in the evening and in the off-season run less often. Taxi lines get long when a busy boat arrives in July or August, so ask your hotel for a pickup if you're staying outside town, arriving late, or traveling with children or lots of luggage. If you plan to explore mountain villages and quieter beaches, reserve a rental car ahead, since cars get scarce in July and August. If you're staying in Naxos Town and taking the bus to the beaches, you can skip the car.
