Santorini or Mykonos: Who Each Island Suits

Santorini if the trip is for two. Mykonos if it is about the nights out. That split is not our invention. It is the one call made by all five sources we checked: GNTO (Greece’s national tourism organisation), Lonely Planet, Condé Nast Traveller in the UK, Condé Nast Traveler in the US, and Rick Steves. Every one of them puts Santorini down for couples or romance and Mykonos for nightlife. Past those two points they disagree, or say nothing.

Both islands are in the Cyclades. Santorini, the ancient Thera (the municipality is still called Thira), is in GNTO’s words a complex of islands at the southern end of the Cyclades, set around a caldera shaped by successive eruptions, with its villages strung along the caldera rim. GNTO calls the sunset over the caldera, watched from Oia, Fira and Imerovigli, “undoubtedly the most renowned sunset in Greece”. Mykonos is GNTO’s “island of the winds”: a Chora of paved lanes, the houses of Little Venice with their wooden balconies right on the sea, the windmills beside them, and beach bars and clubs. GNTO also calls the island “synonymous with cosmopolitanism and luxurious holidays”. Its neighbour Delos, the mythical birthplace of Apollo and Artemis and a UNESCO World Heritage site, is 30 minutes by boat from the Old Port.

The other labels vary. Lonely Planet’s July 2026 list gives Santorini “volcanic drama” and Mykonos “starry nights and dance parties”, and for a quieter version of each it suggests Folegandros instead of Santorini, and Paros, Naxos or Delos instead of Mykonos. Condé Nast Traveler in the US names Santorini for honeymooners and Mykonos for “decadent parties and five-star hotels”. Rick Steves gives each island two of his triangles, calling Santorini a “romantic island” and Mykonos one of “pulsating nightlife”, and saves his three-triangle rating for Hydra.

Santorini and Mykonos side by side

Sources: ELSTAT’s 2021 census; Fraport Greece’s traffic tables (airport passengers count arrivals and departures, residents included, so they are not visitor numbers); ELIME, the Hellenic Ports Association, for cruise traffic; the Santorini Port Fund’s berthing policy; the operators’ own timetables; GNTO.

Which is nicer, Santorini or Mykonos?

It depends on the trip, and the sources line up like this:

• Couples and honeymoons: Santorini, five of five. GNTO’s page on islands for couples says couples choose it for weddings and honeymoons.
• Nightlife: Mykonos, also five of five.
• A first Greek island: either. Lonely Planet says most first-timers choose the Cyclades and home in on these two.
• Ancient sites: both have a major one. Akrotiri, the prehistoric town destroyed by Santorini’s 16th-century BC eruption, costs €20 and closes at 15:30 on Mondays and Thursdays. Delos costs €20 for the site, plus about €25 for the return boat from Mykonos, and swimming is not allowed on its coast. See dates
• Something quieter: Lonely Planet’s swaps are Folegandros for Santorini and Paros or Naxos for Mykonos. See Naxos or Paros and the least touristy Greek islands.
• Families: neither. None of the five sources names either island for families. Their family picks are Crete (both Condé Nast editions), Naxos (Lonely Planet, for water shallow enough for children), Syros and Kefalonia; more in the best Greek islands for families.
• A tight budget: neither. Lonely Planet’s budget guide calls these two the “A-lister” islands.

Pretty is not something a source can settle for you. The nearest thing to a verdict is GNTO reserving its superlative for Santorini’s sunset.

Fees and caps on both islands

Two national charges apply to both islands in exactly the same way.

The cruise-passenger fee has been collected since 21 July 2025 from every cruise passenger who goes ashore, whatever their age. At Santorini and Mykonos it is €20 from June to September, €12 in April, May and October and €4 from November to March; every other Greek port charges €5, €3 and €1. It is levied per passenger at each port, through the cruise line, and nobody arriving by ferry or plane pays it.

The climate resilience fee is charged per room, per night, not per person: from April to October €2 in a one- or two-star hotel, €5 in a three-star, €10 in a four-star and €15 in a five-star, and €8 for a short-term rental, with lower rates from November to March.

Then each island’s own rules. Santorini’s Port Fund allows no more than 8,000 cruise passengers on the same day. Since 2026 it counts every ship at its full capacity rather than 80% of it, and it enforces the limit months ahead through berth allocation, not at the gangway. Since July 2026, ships certified for more than 1,000 passengers must land 70% of them at the Old Port of Fira and 30% at Athinios. We could not find any published daily cap for Mykonos.

On the ground, the Santorini cable car costs €10 one way (it was €6 until 2024); the alternative is the path from the Old Port, 587 steps by the Port Fund’s count. On Mykonos, the Delos boat and the Delos site ticket are bought separately.

What 2025 changed

In 2025 Mykonos edged Santorini for cruise passengers, 1,222,748 to 1,203,052, and only Piraeus received more. Santorini had a hard year.

A swarm of earthquakes began on 27 January 2025 in the sea between Santorini and Amorgos. Officials at first described it as tectonic, not volcanic; peer-reviewed studies published later in 2025 attribute it to a magmatic dike intrusion, magma forcing its way into the crust beneath the seabed. More than 10,000 residents and visitors left the island in early February, the municipality’s state of emergency was extended into July, and the Old Port and the cable car did not reopen until 15 May 2025. Santorini’s airport carried 16% fewer passengers than in 2024, though Fraport says it kept operating throughout, and cruise passengers fell 10.6%. In the first eight months of 2026, airport traffic was back up 4.5%.

What is open now is set by a decision in force until 31 March 2027. The Old Port of Fira, the cable car and the path from the port are open, except for one closed zone of the port. So are Armeni and Ammoudi below Oia, the path from Ammoudi up to Oia, and Korfos on Thirasia. The footpath from Ammoudi to Cape Agios Nikolaos is closed, and vehicles are kept off the road down to Ammoudi, a measure that dates from a May 2024 landslide rather than the earthquakes. Red Beach is a separate case: access has been banned since 2013 because of falling rock, more rock came down in February 2025, and the beach is seen from the sea.

Getting there, and between the two

Both islands have flights from Athens: 50 minutes to Santorini and 45 to Mykonos, by GNTO’s timings. By sea, SeaJets’ 2026 guide gives Piraeus to Mykonos as 2 h 40 (from €80), and its Worldchampion Jet reached Santorini 5 h 35 out of Piraeus on its 2025 summer schedule. From Rafina, the port closest to Athens airport, Golden Star takes 2 h 30 to Mykonos and 5 h 30 to Santorini. Blue Star’s conventional ships take about 8 hours from Piraeus to Santorini on the day route, and 4 h 40 overnight to Mykonos by way of Syros.

Between the two islands the fast boats go by way of Paros and Naxos. SeaJets times the legs at 35 to 50 minutes from Mykonos to Paros, 25 to 30 minutes from Paros to Naxos and 1 h 10 to 1 h 30 from Naxos to Santorini; on the Worldchampion Jet’s 2025 timetable, Santorini came 2 h 45 after Mykonos (our arithmetic). Golden Star gives 1 h 15 from Mykonos to Paros and 1 h 45 from Paros to Santorini.

Allow for the wind. The meltemi, the northerly summer wind, blows from June and often reaches gale force in the Aegean; in June 2025 it was strong on 24 of the 30 days. SeaJets itself advises a spare day before a flight home in July and August. In winter, Mykonos airport’s runway is closed every Thursday from 19 November 2026 to 18 March 2027 for rebuilding, except on 23, 24 and 31 December and 6 and 7 January.

Is Santorini or Mykonos cheaper?

No official source compares the two, and the charges set by law are identical: the same cruise fee and the same per-room climate fee. Lonely Planet’s budget guide treats both as “A-lister” islands. The featured tours start from $84 on Santorini and from $99 on Mykonos (October 2026), with the €20 Delos ticket on top of the Mykonos cruise, but that compares two different days out more than two islands. For the islands that do cost less, see the cheapest Greek islands.

How many days in Mykonos is enough?

No authority sets a number. Lonely Planet’s advice for island-hoppers is one island group and two or three islands in a week, which works out at two or three days an island; on Mykonos that is enough for Chora, a beach and Delos. The Delos boats leave the Old Port at 09:00, 10:00 and 11:30 from Tuesday to Sunday, with a later sailing in the afternoon from May to October, and the crossing takes 30 minutes. The 2026 boat season runs from 1 April to 30 November, and the site lists no weekly closing day.

What are the three best Greek islands to visit?

There is no agreed top three. Rick Steves’ Greece overview is the only source we read that names just three islands, and it rates them in this order: Hydra, then Mykonos and Santorini. The others choose by purpose. Lonely Planet’s twelve run from Ikaria to Kea, and both Condé Nast editions name Crete for families. Our homepage sets out who each island suits, and the map of the Greek islands shows where they all are.
