Which Greek Island Should You Visit?

The best Greek islands to visit depend on the trip you have in mind, and no single island wins for everyone. Read five of the guides that recommend islands side by side (Visit Greece, the Greek National Tourism Organisation’s site; Lonely Planet; Condé Nast Traveller in the UK; Condé Nast Traveler in the US; and Rick Steves) and they agree on two things only: Santorini for couples and Mykonos for nightlife. Beyond those two, they split.

This page compares eleven islands from five of the eight groups Visit Greece sorts them into. Santorini, Mykonos, Milos, Paros and Naxos are in the Cyclades. Crete is a group of its own, Rhodes is in the Dodecanese, and Corfu, Kefalonia and Zakynthos are in the Ionian Sea. Hydra is one of the Argo-Saronic islands, close to Athens. Each island has its own page with a featured day out, the other tours listed for it and where each one leaves from.

Pick the trip first. Then check how you would get there, and what is open in the month you go.

Who should pick which

Each pick below names the guide behind it.

• Couples: Santorini, in all five. The Rick Steves page calls it a “romantic island”, and Condé Nast Traveler (US) makes it the honeymooners’ island. Visit Greece’s own list for couples adds Milos and Amorgos, and Lonely Planet gives Kefalonia “rugged romance”. The honeymoon guide weighs them up.
• Nightlife: Mykonos, again in all five. The Rick Steves page mentions its “pulsating nightlife”, and Condé Nast Traveler (US) its “decadent parties and five-star hotels”.
• Families: Crete, in both Condé Nast editions. Lonely Planet suggests Naxos, “where kids can safely swim in shallow waters”, and names Syros “especially for families”; Condé Nast Traveler (US) adds Kefalonia for laid-back family vacations. The families guide goes through them.
• A first trip: Lonely Planet says most first-timers choose the Cyclades and home in on Santorini and Mykonos. Condé Nast Traveler (US) says that if you are unsure, “Crete is your best bet”.
• History: Lonely Planet picks Crete for archaeology and Rhodes for medieval history. Crete’s six “Minoan Palatial Centres”, Knossos among them, joined UNESCO’s World Heritage List together in July 2025.
• The sea: Lonely Planet calls Milos the island for underwater exploration and counts “more than 70 beaches” there; Visit Greece counts 80. Condé Nast Traveller (UK) picks Crete for beaches, and Lonely Planet picks Corfu for boating. The beaches guide compares the coasts.
• A short trip from Athens: Hydra. The Rick Steves page rates it above Santorini and Mykonos and calls it “convenient to Athens”; Condé Nast Traveler (US) suggests it for a long weekend. Cars and motorbikes are not allowed on the island (Visit Greece).
• Hiking and nature: Kefalonia, in Condé Nast Traveller (UK).
• A tight budget: of the five, only Lonely Planet takes this on. It calls Santorini and Mykonos “A-lister” islands, says bargains are hard to find from July to September, and calls Crete “one of the most affordable destinations in the Mediterranean”. The cheapest islands adds what drives the cost.
• Paros or Naxos: Condé Nast Traveller (UK) chooses Paros for an authentic experience. Lonely Planet sends families to Naxos and names both as quieter alternatives to Mykonos. Naxos or Paros sets them side by side.
• Zakynthos: none of the five matches it to a kind of traveler. Visit Greece calls it a haven for loggerhead turtles, and its best-known beach, Navagio, is closed to landing until 31 October 2026.

Two more matchups have pages of their own: Santorini or Mykonos and Crete or Santorini.

Eleven islands side by side

Flight times are Visit Greece’s, from Athens. Ferry times are the operators’ own where they publish one. The crowd figures are the closest official proxies: passengers arriving on international flights in 2025, from the civil aviation authority (HCAA), and cruise passengers landed in 2025, from the Hellenic Ports Association (ELIME).

On a phone, swipe the table sideways.

Crete and Rhodes are a night or most of a day from Piraeus by ferry, so for a short trip you fly. Milos, Naxos and Paros get almost no international flights; you reach them through Athens or by sea.

How many islands there are

Visit Greece puts the total at “6,000 islands and islets”, “of which only 227 islands are inhabited”, without a year or a definition. The census-based count is lower: 114 inhabited islands at the 2011 census, plus 440 islets recorded with no population, according to the University of the Aegean’s island atlas. Lonely Planet says 2,000-plus, about 250 of them inhabited. Totals run from 1,200 to 6,000 depending on how small an islet you count, and no count from the 2021 census could be found. How many Greek islands are there sets the counts and the island groups side by side.

The quieter islands

For fewer people, the guides point beyond these eleven. Lonely Planet and Condé Nast Traveller (UK) both pick Kythnos, and the UK edition adds Kastellorizo. Lonely Planet sends couples “seeking serenity and umbrella-free beaches” to the Small Cyclades and suggests Folegandros instead of Santorini, and Visit Greece calls Amorgos “a tranquil romantic refuge”. The numbers bear the quiet out: Folegandros landed 434 cruise passengers in 2025, Santorini 1,203,052. What these islands trade is access. Folegandros and Amorgos have no airport, and Visit Greece routes you by ferry from Milos (55 minutes to 2 h 50) or from Naxos (1 h 15 to 6 h). Water is short on some small islands too: Patmos and Leros were declared water-scarcity emergencies in November 2025, later extended, and Astypalaia in May 2026. The least touristy islands takes them one by one, with how to reach each.

One island, two or three

Lonely Planet’s advice for a week is one island group and two or three islands. The Cyclades make that easy. By SeaJets’ own times, Paros to Naxos takes 25 to 30 minutes, Mykonos to Paros 35 to 50, Naxos to Santorini 1 h 10 to 1 h 30, and Santorini to Milos 1 h 55. Crete links to Santorini by Blue Star’s conventional ferry and SeaJets’ high-speed boats, Rhodes to Symi by boats of about 45 minutes to 1 h 30, and Kefalonia to Ithaca by a 31-minute crossing from Sami, in Visit Greece’s timing.

The Ionian islands are a separate trip. No ferries run to them from Piraeus, Rafina or Lavrio; they sail from Kyllini, Patras, Astakos or Igoumenitsa on the mainland, so pairing Corfu or Zakynthos with the Cyclades means a mainland crossing or a flight.

Two more things to plan around. The ferry timetable year runs from 1 November to 31 October, and some links run only in high summer: Fast Ferries calls at Paros from Rafina only between 13 June and 13 September 2026. And the meltemi, the north wind of the Aegean summer, blows from June, when it was strong on 24 of the 30 days in 2025, and it can stop sailings: on 14 August 2026 ships were held in Rafina and Lavrio until 16:00. SeaJets itself advises a spare day before a flight in July and August. Island hopping has the routes and realistic combinations, and the islands map shows where each island sits and which ports link them.

What changed in 2025 and 2026

Since 21 July 2025, cruise passengers pay a fee at every Greek port where they land, whatever their age: €20 at Santorini and Mykonos from June to September, €12 in April, May and October and €4 from November to March, and €5, €3 or €1 at every other port; ferry and air passengers do not pay it. The climate resilience fee that hotels and rentals add per room per night, not per person, has been €2, €5, €10 or €15 by star rating from April to October since 2025, €8 for short-term rentals, and less from November to March. On Santorini, the earthquake swarm that began on 27 January 2025 was a magmatic dike intrusion according to peer-reviewed studies published that year, with counts from about 25,000 to more than 50,000 quakes depending on the method; a state of emergency declared in February 2025 was extended into July 2025, and the cable car and Old Port reopened on 15 May 2025. The access decision now in force runs to 31 March 2027: the Old Port, the cable car, Armeni, Ammoudi village and the path from Ammoudi up to Oia are open, while the footpath from Ammoudi to Cape Agios Nikolaos, one zone of the Old Port and the Ammoudi road, closed to most vehicles since a May 2024 landslide measure, stay shut. Red Beach has been closed to visitors since 2013, and boats view it from offshore. As of early October 2026, Samaria Gorge on Crete has been closed at both entrances “until further notice” since 1 October after storms and floods across the island, and Knossos shut from 14:00 on 3 October because of the weather. Navagio on Zakynthos is closed to landing and swimming until 31 October 2026; boats may pass only through a buoyed viewing zone, for 20 minutes at most and 15 boats at a time. Check the island page and the tour’s calendar in the week you book.

Guides for the next decision

Each guide takes one of these questions further: Santorini or Mykonos, Naxos or Paros, Crete or Santorini, a honeymoon, families, beaches, the cheapest islands, island hopping, the quieter islands, the islands map and how many islands there are.
