Crossing from Santorini to Mykonos is the classic Cyclades island-hopping route, running about 2 to 3 hours by high-speed boat, with daily sailings in summer from around 45 to 90 euros. This guide covers the journey time, the prices, the operators, the schedules and tips for booking the ferry.
This route links Greece’s two most famous islands, a key connection in the wider Santorini travel guide. Both lie in the Cyclades. The sections below cover the ferry.
How long is the Santorini to Mykonos ferry?
This crossing takes about 2 hours 30 minutes on average, ranging from around 1 hour 50 minutes on the fastest high-speed boats to about 3 hours 20 minutes on slower high-speed ferries. It is a top Cyclades island-hopping route.
The crossing between Santorini and Mykonos is quick and direct. On average the ferry takes around two and a half hours. The exact time depends on the operator and vessel. The fastest SeaJets high-speed catamarans make the run in about 1 hour 50 minutes. The slower high-speed ferries take up to roughly 3 hours 20 minutes. All are passenger high-speed services with air-conditioned lounges and open decks. They cross the open Aegean between the two best-known islands of the Cyclades.
The route ranks among the busiest in the Aegean, so it pays to plan ahead. It sits within the wider guide to how to get to Santorini. The cost of the ticket varies with the operator and the class of seat, and the section below breaks it down.
How much does the ferry cost?
The Santorini to Mykonos ferry costs roughly 45 to 90 euros one way for a foot passenger, depending on the operator, season and seat class. High-speed SeaJets services run around 70 to 89 euros, while economy seats on slower ferries cost less.
Fares on the route span a wide band. A one-way ticket for a foot passenger costs between about 45 and 90 euros. The price varies with the operator, the season and the class of seat you choose. The fast SeaJets vessels cost around 70 to 89 euros. Economy seats on the Golden Star high-speed ferries cost less, at roughly 60 to 78 euros, with premium and business-class seats priced higher.
Prices climb in the peak July and August period and when boats fill up. Booking early secures both a place and a better fare. The fare structure sits alongside the guide to a Santorini itinerary. The schedule is dense in summer, and the operators section covers the frequency.
What is the schedule and who are the operators?
The ferry is operated by SeaJets and Golden Star Ferries, with around 52 weekly sailings from June to September, often three or four a day, dropping to about 8 a week from October to May. High-speed boats dominate the route year-round.
The frequency of the route swings sharply with the season. In the summer months from June to September, the two operators SeaJets and Golden Star Ferries run around 52 sailings a week between Santorini and Mykonos. That works out to three or four departures a day, giving broad flexibility for island-hopping. Outside the season, from October to May, the count drops to roughly eight sailings a week.
Winter and shoulder-season travellers therefore work around a thin timetable. The route is served almost entirely by high-speed vessels, which are quick but more affected by rough seas. The frequency sits alongside the guide to the best time to visit Santorini. Practical tips help you catch the boat, and the sections below cover booking, seats and vessel types.
How do you book Santorini to Mykonos ferry tickets?
You book Santorini to Mykonos ferry tickets online in advance, receiving an e-ticket with a booking reference. Print the ticket or collect a paper boarding pass at the port desk before departure, and reserve early for summer dates.
Booking the crossing online is the direct route. You choose the date, operator and seat class, then pay and receive an e-ticket carrying a booking reference. Some fares need collection as a paper boarding pass at the operator desk in the port before you board. Print the e-ticket or save the reference on your phone so the desk finds your reservation fast.
Reserve early for the June-to-September peak, when the popular morning and midday departures sell out. A confirmed seat locks in both the sailing and the fare before prices climb in July and August. Keep the booking reference, passenger names and passport details ready, since operators check them at the desk and at boarding.
What is the best ferry from Santorini to Mykonos?
The best ferry depends on your priority. A fast SeaJets catamaran covers the crossing in about 1 hour 50 minutes for speed, while a steadier high-speed ferry taking up to 3 hours 20 minutes handles a choppy Aegean more calmly.
Choosing between the boats comes down to a trade-off. The SeaJets high-speed catamarans are the quickest option on the route, reaching Mykonos in about 1 hour 50 minutes. That speed suits travellers who want the shortest time on the water and an early arrival. The catamaran hull rides fast but reacts more to swell in rough conditions.
A larger high-speed ferry taking up to 3 hours 20 minutes trades pace for a steadier ride. Golden Star Ferries run this heavier type, which many passengers find calmer when the meltemi wind stirs the open Aegean. Weigh the shorter crossing of the catamaran against the smoother deck of the bigger ferry, and match the choice to the sea forecast for your date.
What are the ferry types on this route?
Two ferry types serve the route. High-speed catamarans run by SeaJets use twin hulls for pace, while high-speed monohull ferries from Golden Star Ferries use a single larger hull for a steadier ride across the open Aegean.
The route is a high-speed corridor with two distinct vessel designs. The catamaran uses twin parallel hulls, which cut drag and push the fastest crossing times down toward 1 hour 50 minutes. The design carries foot passengers in air-conditioned lounges and reaches Mykonos quickly, at the cost of a livelier ride when the sea turns.
The monohull high-speed ferry uses one larger hull. It runs up to 3 hours 20 minutes on the same route, trading pace for stability and a heavier, calmer feel on deck. Both carry the same air-conditioned lounges and open-deck access, so the core difference is speed against steadiness rather than comfort inside the cabin.
Which seats should you book?
Book numbered or economy seats for the lowest fare, or business and premium seats for extra space and quiet. Window seats give the caldera and Aegean views, aisle seats give easy movement, and mid-ship seats feel the least motion.
Seat class shapes both the fare and the ride. Economy or numbered seats carry the lowest price and place you in the main lounge. Business and premium cabins cost more and add wider seats, extra legroom and a quieter space away from the busiest lounge. Choose the class against your budget and the length of the crossing.
Position matters too, and a short list helps:
- Window seats frame the caldera on departure and the open Aegean during the run.
- Aisle seats give quick access to the bar, the deck and the exits.
- Mid-ship seats sit over the vessel’s centre of balance and feel the least motion.
- Open-deck access lets you step outside for air on the high-speed boats.
Where do you catch the ferry and arrive?
You catch the ferry at Athinios port on Santorini, the main harbour below the caldera cliffs, and arrive at Mykonos New Port. Both harbours sit outside the main towns, so plan buses or taxis at each end and arrive early.
Athinios is the working port of Santorini, set below the caldera cliffs a winding road down from the island’s centre. Buses and taxis link the port to Fira and the villages, and the road fills before big departures. Reach Athinios in good time, since the descent and the boarding queue both take longer than travellers expect.
On arrival, the boats dock at Mykonos New Port, north of Mykonos Town. Buses, taxis and hotel transfers wait at the harbour to carry passengers into town and to the beaches. Both ports sit outside the main centres, so build the transfer into your timing at each end and keep your booking reference handy for the return leg.
What tips help for the ferry?
The tips are to book 1 to 2 months ahead for summer, or 2 to 3 for popular departures, arrive at the port 45 to 60 minutes before departure, and allow flexibility, as strong meltemi wind can delay or cancel boats in midsummer.
A well-planned crossing runs smooth. This is one of the busiest Cyclades routes, so booking ahead is strongly advised. Aim for one to two months in advance for summer travel, and two to three months for the most popular departures, which sell out. On the day, arrive at the port 45 to 60 minutes before departure, as boarding and the busy Athinios port take time.
Build in flexibility too. The high-speed boats that serve the route can be delayed or cancelled by the strong meltemi wind that blows in July and August, disrupting Cyclades sailings. With tickets booked early, the route makes combining Santorini and Mykonos easy. It sits alongside the guide to Santorini vs Mykonos. The questions below cover the points travellers ask most.
Can you get seasick on this crossing, and how do you avoid it?
You can get seasick on this crossing, as it runs the open Aegean where fast boats bounce more in the meltemi wind. Reduce it by booking mid-ship seats, taking motion medication beforehand and watching the horizon on deck.
The route crosses open Aegean water, and the high-speed boats react to swell more than heavier vessels do. The meltemi wind of July and August raises the sea and makes the ride livelier, so motion sickness is a real risk for travellers prone to it. The catamarans in particular bounce over waves at speed, which unsettles some passengers.
Four steps cut the risk on the crossing:
- Book mid-ship seats, where the vessel’s motion is smallest.
- Take motion-sickness medication before boarding rather than after symptoms start.
- Step out to the open deck and fix your eyes on the horizon.
- Eat lightly beforehand and keep water within reach during the run.
Can you take a car or luggage on the ferry?
The high-speed passenger boats on this route carry limited or no vehicle space, so a car is rarely an option. Luggage travels with you, stored in racks near the entrance, and you carry cabin bags to your seat aboard.
The Santorini to Mykonos corridor runs on high-speed passenger vessels built for pace rather than freight. Vehicle space is limited or absent on the catamarans, so drivers usually rent a car separately on each island instead of shipping one across. Check the specific sailing if a vehicle is essential, as availability is the exception on this fast route.
Luggage travels with the passenger. Larger cases go into open racks near the boarding doors when you step aboard, and staff point you to the racks during boarding. Carry cabin-sized bags, valuables and travel documents to your seat. Label your cases clearly, since the racks fill fast on busy summer departures and bags sit together.
Can you do a day trip from Santorini to Mykonos?
You can do a day trip from Santorini to Mykonos using an early sailing out and a late one back, but the crossing runs about 2 hours 30 minutes each way, so the day is long. An overnight stay works far better.
A same-day return is possible on paper. The summer timetable of around 52 weekly sailings includes early-morning and late-afternoon departures, which frame a window on Mykonos between the two crossings. The catch is the travel time: at about 2 hours 30 minutes each way, five hours of the day disappears on the water before you count boarding and transfers.
That long transit leaves a short slice of Mykonos itself, and any delay from the meltemi wind risks the return boat. An overnight stay turns the same trip into a relaxed two-island break, with a full day on Mykonos and no rush for the last sailing. Reserve both crossings early if you attempt the day trip, since the framing departures sell out first.
