Santorini to Mykonos 2026: Ferry, Flight & Day-Trip Guide
Last updated: May 28, 2026
Every summer, thousands of travelers face the same question: what’s the best way to get from Santorini to Mykonos? These two islands are the twin pillars of the Cyclades experience, caldera sunsets on one end, whitewashed windmills on the other, and the route between them is one of the most traveled in the Greek islands. At Discover Cyclades, we have helped thousands of travelers navigate this crossing, and this guide covers everything you need to know: ferry options, flight alternatives, whether a day trip is realistic, and the smartest way to book.
The Quick Answer
| Option | Duration | Price (one way) | Frequency | Best For |
|---|---|---|---|---|
| High-speed ferry | 2–3 hours | €60–€90 | 1–3 daily (summer) | Most travelers |
| Domestic flight | ~45 min flight + transfers | €80–€160+ | Seasonal, limited | Travelers with tight schedules |
The ferry wins for most people. It’s cheaper, more scenic, and, when you factor in airport transfers on both ends, rarely slower door to door.

The Ferry: Your Best Option
Route and Ports
All ferries depart from Athinios Port on Santorini, located about 12 kilometers south of Fira. You’ll need to arrange transport down the switchback road to the port, taxis, buses, and hotel transfers all serve this route. Plan to arrive at least 40 minutes before departure.
The ferry docks at Mykonos New Port (also called the Old Port area is nearby but most high-speed services use the larger New Port). From there, it’s a short bus or taxi ride into Mykonos Town (Chora).
Operators and Journey Time
Three main operators run this route in 2026:
SeaJets is the most popular choice and typically the fastest. Their high-speed catamarans complete the crossing in around 2 hours. They run multiple daily departures during peak season and are the operator that sells out first, book early.
Golden Star Ferries is another solid high-speed option. Their vessels are comfortable and well-maintained, with journey times in the 2.5-hour range. They tend to have more availability than SeaJets when you’re booking last minute.
Minoan Lines (seasonal) offers a slightly slower but larger vessel option, occasionally with an intermediate stop at a smaller island. Journey time can stretch to 3 hours with stops, but the ships are roomier and the deck experience is excellent.
Fares and Classes
Economy class on any of these operators will cost approximately €60 to €90 per person one way in 2026. A few things to know:
- Prices are dynamic. Booking 4–6 weeks in advance consistently yields the cheapest fares.
- There’s rarely a meaningful quality difference between economy classes on these high-speed vessels, the journey is short enough that a premium seat is rarely worth the extra cost.
- Bicycles and scooters can usually be transported for an additional fee; check directly with the operator.
Seasonality
Service is robust from late May through early October. Outside of that window, sailings become infrequent or stop entirely. In July and August, you may find two or even three sailings per day. In early May or late October, you might find only one per week. Always check current schedules on the Discover Cyclades ferry tickets page or directly with the operators before finalizing your dates.
The Flight Option
A domestic flight between Santorini (JTR) and Mykonos (JMK) takes roughly 40–45 minutes in the air. Sky Express operates this route during the summer season, with limited frequencies compared to the ferry.
However, flying has real drawbacks on this particular route:
- Transfer time erodes the advantage. Santorini's airport is about 6 kilometers from Fira, and Mykonos airport is about 3 kilometers from the town. Add check-in, security, and baggage claim, and the total journey time frequently exceeds 3.5 hours, comparable to or longer than the ferry.
- Cost is higher. Once you add airport transfers on both sides, flights are rarely cheaper than the ferry.
- Weather risk. The Aegean wind (meltemi) disrupts small domestic flights far more often than it affects large high-speed ferries.
When does flying make sense? If you’ve a very tight connection, say, arriving in Santorini in the morning and needing to be in Mykonos for an evening event, and you can find a well-timed flight, it can work. For almost everyone else, the ferry is the smarter choice.
Is a Day Trip Realistic?
We get this question constantly. The honest answer: technically yes, but we don’t recommend it.
Here’s why. The first ferry from Santorini to Mykonos typically departs around 7:00–8:00 AM (times vary by season and operator). The return sailing back to Santorini usually leaves Mykonos in the late afternoon, giving you perhaps 4–5 hours on the island. After accounting for port transfers on both ends, you’re realistically looking at 3–4 hours of actual time in Mykonos Town.
For €120–€180 in round-trip ferry tickets, that’s a costly half-day. Mykonos deserves at least one full evening, the island transforms after sunset, the cocktail bars along Little Venice come alive, and the famous windmills glow in golden light. A single overnight stay changes everything.
Our recommendation: plan at least one night in Mykonos hotels. If your itinerary is tight, two nights is the sweet spot.
Best Time to Travel and Booking Tips
Late June and early September offer the best balance of reliable service, warm weather, and manageable crowds. July and August are peak season: ferries run frequently, but they also fill up fast and prices spike.
Booking timeline:
- July / August travel: book 4–6 weeks ahead, especially for SeaJets morning departures
- June / September travel: 1–2 weeks ahead is usually sufficient
- May / October travel: check availability carefully as some operators have very limited schedules
When booking, always double-check the departure port listed on your ticket. Santorini occasionally sees ferries stopping at the smaller port of Oia/Ammoudi for day cruises, make sure you’re booked on a service departing from Athinios.
Arriving in Mykonos: New Port vs Old Port
Most high-speed ferries from Santorini dock at Mykonos New Port, located about 2.5 kilometers north of Mykonos Town. From the New Port, buses run regularly into Chora during peak season, and taxis are usually available (though they can be scarce at peak arrival times, have your accommodation's address ready and consider pre-booking a transfer).
A handful of services dock at the Old Port, which is more central and within walking distance of the town center. Your ticket will specify which port. If you’re staying in or near Mykonos Town, an Old Port arrival saves you time and taxi fare.
One tip we always give travelers: don’t assume your luggage will be close to you on a high-speed catamaran. Bags are often stored in a separate hold. Keep your daypack with essentials on board and retrieve your main luggage after docking.
Our Verdict
The Santorini to Mykonos crossing is one of the great short sea journeys in Europe. On a clear summer morning, watching the caldera of Santorini shrink behind you while the whitewashed cube houses of Mykonos appear on the horizon is genuinely memorable. Take the ferry, book early, allow at least one night on each island, and you’ll understand why this route remains one of the most beloved in the Cyclades.

Frequently Asked Questions
How long is the ferry from Santorini to Mykonos?
The high-speed ferry from Santorini (Athinios port) to Mykonos takes approximately 2 to 3 hours depending on the operator and whether it makes intermediate stops. SeaJets and Golden Star Ferries run the fastest crossings in peak season.
How much does the Santorini to Mykonos ferry cost?
Economy class tickets on the high-speed ferry typically cost between €60 and €90 per person one way in 2026. Prices vary by operator, travel date, and how early you book. Booking 4–6 weeks ahead usually secures the best fares.
Can you do Santorini to Mykonos as a day trip?
Technically possible but not recommended. Ferries usually depart in the morning and the return crossing in the afternoon gives you only 4–5 hours on Mykonos. Given the cost and effort involved, staying overnight makes the trip far more rewarding.
Is it better to fly or take the ferry from Santorini to Mykonos?
The ferry is almost always the better choice. It’s cheaper, more frequent in peak season, and the Aegean scenery makes it an experience in itself. Domestic flights operate only during summer, are often more expensive when you factor in airport transfers, and are heavily weather-dependent.
How far ahead should you book the Santorini to Mykonos ferry?
For July and August travel, book at least 4–6 weeks in advance. Specific sailings, particularly morning departures on SeaJets, sell out weeks before peak weekends. Outside of July and August, 1–2 weeks ahead is generally sufficient.
