Santorini to Mykonos Ferry

Two companies run the Santorini to Mykonos ferry route: Seajets, with most of the sailings, and Golden Star Ferries, with one a day. The fastest was the Seajets SuperCat Jet 2 in summer 2026, leaving Athinios at 09:20 and reaching Mykonos at 11:15, just under two hours. Economy tickets cost €59.70–89.20 depending on the boat. The one thing first-timers should know: every sailing on this route is a high speed ferry, the service is seasonal, and in July and August the good morning departures sell out, so book early.

Santorini and Mykonos are about 59 to 64 nautical miles apart, at the southern and northern ends of the central Cyclades. There are no conventional ferries on this crossing, so your choice is between faster and slower high speed boats, and between a direct sailing and one with stops at Naxos, Paros or Ios.

Ferry options compared

Seajets

Seajets is the main ferry company on the route and runs most of the ferries from Santorini to Mykonos. In summer 2026 its main departures were:

• SuperCat Jet 2, 09:20: direct to Mykonos in just under 2 hours (1 h 55 min). This is the fastest ferry on the route. It then returns from Mykonos at 11:50 and reaches Santorini at 13:45.
• Worldchampion Jet / Champions League Jet 1, 09:50: stops at Naxos and Paros, arriving in Mykonos at 12:20 (2 h 30 min). This boat starts in Heraklion, Crete, and continues to Tinos, Syros and Piraeus.
• Other Jet vessels: on some days in peak season, Seajets adds midday and afternoon sailings with crossings from about 2 h 10 min to over 4 hours.

Seajets boats have numbered seats in air-conditioned lounges, with economy, Club-Business and Platinum or VIP seats. There is a café or snack bar, but you cannot sit outside while the vessel is under way. Luggage goes on racks by the entrance.

Golden Star Ferries

Golden Star Ferries runs one high speed ferry a day on this route, the Golden Princess (listed as Super Express). In 2026 it left Santorini at 14:15 from 1 May to 31 October, called at Ios and Paros and reached Mykonos at 17:35 (3 h 20 min), before continuing to Tinos and Rafina. It is slower but gives you a relaxed morning on Santorini and a late-afternoon arrival in Mykonos. Golden Star Ferries is also useful if you are heading on to Tinos or to Rafina, the second ferry port of Athens.

Booking sites also list Fast Ferries on this route in some seasons; we could not confirm a 2026 timetable, so check live listings.

Which ferry for which traveller

• Shortest time at sea: Seajets at 09:20.
• Want to see Naxos and Paros on the way: Seajets at 09:50.
• Late checkout, slow morning: Golden Star Ferries at 14:15.
• Prone to seasickness: the direct 09:20 boat keeps your time at sea shortest; choose a seat in the middle of the vessel.
• Travelling to Mykonos and then Athens: the Seajets boat continues to Piraeus; the Golden Star boat continues to Rafina.

Timetable and season

This is a seasonal route. Based on the 2026 published timetables:

• May to early October (high season): the full ferry schedules, with up to 4–5 crossings per day in peak summer. Direct Ferries counted around 21 sailings per week, about 16 by Seajets and 6 by Golden Star. The first ferry leaves around 09:20–09:50 and the last around 14:15–18:35 depending on the day.
• April and October: fewer boats. The Seajets service via Naxos and Paros ran daily at 10:05, arriving at 13:05.
• November to March: Ferryhopper lists Santorini to Mykonos sailings from roughly March to November. In winter you may need to change boats or travel via Athens.

Journey times and departure times vary depending on the ferry and the day of the week in shoulder season, so check the timetable for your exact date.

Getting to Athinios port in Santorini

The departure port for every ferry from Santorini to Mykonos is Athinios port, also called the New Port or Thira Santorini port, below the caldera cliffs.

• Distance: about 8 km from Fira, 10 km from Santorini airport and 20 km from Oia.
• Bus: KTEL buses run from Fira to Athinios for €2.70, taking about 20 minutes. Port buses are timed around ferry departures rather than running every hour, so check the times posted at Fira bus station the day before. From Oia you must change in Fira.
• Taxi and transfers: taxis are scarce, with only about 25 on the island. Pre-book a transfer or ask your hotel.
• Timing: the road down to Athinios is steep and narrow with tight switchbacks, and it jams when several ferries depart together. Aim to be at the port 45 to 60 minutes before departure.

The port has ticket offices, cafés, a minimarket, an ATM and a waiting room. Our Santorini ferry port guide has more detail.

Arriving in Mykonos

Ferries from Santorini dock at the New Port in Tourlos, about 2 km north of Mykonos Town (Chora). The Old Port in town is mainly used by small boats, Delos excursions and cruise tenders.

• Sea Bus: a small boat runs from the New Port to the Old Port in town about every 30 minutes from April to October, taking about 12 minutes. Tickets cost about €2–2.50.
• KTEL bus: buses wait inside the port area and run to Mykonos Town and the airport. Luggage goes underneath.
• Taxi: there is a taxi stand at the New Port, but when two or three ferries arrive together the queue can be long. Pre-book if you have a lot of luggage.
• Hotel transfer: many hotels offer pickups; book ahead.

See our Mykonos ferry port guide for onward travel.

Santorini to Mykonos with a stop

Because most boats call at other islands, the Santorini to Mykonos ferry route is easy to break into two short hops. Instead of a single trip from Santorini, you can buy two separate ferry tickets and spend a few nights on the way:

• Naxos or Paros: the 09:50 Seajets boat calls at both, and the 14:15 Golden Star Ferries boat calls at Paros. Both islands have frequent onward boats to Mykonos in summer. See Santorini to Naxos and Santorini to Paros.
• Ios: the Golden Star Ferries boat and some Seajets boats stop at Ios. See Santorini to Ios.

Splitting the ferry crossing costs a little more in total, but the legs are short, usually under two hours each. It is often the best way to add a quieter island to a Santorini and Mykonos trip. If the meltemi is blowing, shorter hops also mean less time on rough water.

Tickets and prices

You can book ferry tickets on the Seajets and Golden Star Ferries websites (each has its own booking engine), or compare all sailings on Ferryhopper or Direct Ferries. You get an e-ticket or QR code to show at boarding.

What drives the price:

• Vessel: Seajets economy fares ranged from €59.70 on some inter-island boats to €89.20 on the boat that continues to Piraeus.
• Class: Club-Business and Platinum or VIP seats cost €74.70 to over €150 on Seajets, depending on the vessel.
• Cars: these high speed ferries carry cars, but vehicle fares are high and space sells out.
• Round trip: Seajets offered a 40% discount on the return ticket for same-day inter-Cycladic trips from June 2026.

When to book: in July and August, booking in advance is highly recommended; book one to two weeks ahead for the 09:20 and 09:50 boats. Weekends and Greek public holidays such as 15 August are the busiest. In May, June and September a few days ahead is usually enough.

Tips

• Meltemi winds: the strong summer north wind can cause delays and cancellations, and the open stretch between the islands can be rough. Take seasickness tablets before boarding if you need them, and do not plan a same-day flight home from Mykonos after the ferry.
• Seat choice: seats are numbered, so there is no need to queue early for a good spot. A seat low and in the centre of the boat moves least.
• Food: snack bars sell coffee, sandwiches and drinks. Bring water.
• Luggage: keep medication, passports and valuables with you, as big suitcases are stored away from your seat.
• Pets: rules for pets differ by operator; declare them when you book.

Mykonos and Santorini are the two most visited Cyclades islands, so this leg fits most island hopping itineraries. Continue from Mykonos to Paros or Naxos, or back to Athens. See our Cyclades ferry itinerary, Greek island hopping guide, and the Seajets and Golden Star Ferries pages.
