🪪 The quick answer
📍 The island groups
The Greek islands fall into groups with very different characters. The Cyclades, in the middle of the Aegean, are the white islands of the photos. Crete is a world of its own. The Dodecanese lie to the east, close to Asia Minor. The Ionian islands are green, in western Greece. The Saronic islands are right next to Athens. The Sporades and the North Aegean are further north and quieter.
🗺️ The groups of Greek islands
Each colour is one island group: orange the Cyclades, red Crete, purple the Dodecanese, green the Ionian, blue the Saronic Gulf, teal the Sporades and grey the North Aegean. Tap each dot for the island’s name.
| Group | Character | Well-known islands | From Athens |
|---|---|---|---|
| Cyclades | White villages, dry landscape, wind, clear water | Santorini, Mykonos, Naxos, Paros, Milos, Folegandros | Ferry 2.5–8 hours, flights to the big ones |
| Crete | A whole world: cities, gorges, ancient sites, beaches | Heraklion, Chania, Rethymno, Agios Nikolaos | Flight or overnight ferry |
| Dodecanese | Close to Asia Minor, knights and Italian architecture | Rhodes, Kos, Symi, Patmos, Karpathos | Mostly by plane |
| Ionian | Green islands, Venetian heritage | Corfu, Kefalonia, Zakynthos, Lefkada, Ithaca | Flight, or KTEL bus and ferry from the west |
| Saronic Gulf | The closest, for a day or a weekend | Aegina, Agistri, Poros, Hydra, Spetses | Fast ferry 40 minutes to 2.5 hours |
| Sporades | Pine trees down to the sea, the green northern Aegean | Skiathos, Skopelos, Alonissos | Flight to Skiathos or ferry from Volos |
| North Aegean | Big, authentic islands, less tourism | Lesvos, Chios, Samos, Ikaria | Flight or overnight ferry |
📅 Start with the number of days
The most important question is not which island is the most beautiful, but how many days you have. Every change of island means suitcases, a port, a possible delay and half a day lost. Here is what fits:
Saronic Gulf
Aegina for ease or Hydra for atmosphere. From Ioulianou 50, Line 1 to Piraeus and an early fast ferry.
One island
One Cycladic island, such as Naxos, Paros or Santorini, with no changes. Or Hydra and Aegina with Athens as your base.
Up to two islands
Santorini and Naxos, Paros and Antiparos, or just Crete, focusing on one side of it.
Up to three islands
For example Naxos, Santorini and Crete, or Milos, Folegandros and Santorini. No more.

🏝️ If it’s your first time
For a first Greek island, Naxos is often the most balanced choice: beaches, the Chora, villages, food, ancient sites, reasonable prices and good links with Piraeus. Paros is more stylish and more social. Crete works on another scale: cities, gorges, archaeology, beaches and villages, and it stays alive even out of season.
Santorini is the right choice if you know why you are going: the caldera, Akrotiri, wine, the volcanic landscape. If you choose it only for the photo of Oia, high season will feel harsh.

🏖️ If you want beaches
For sand and easy swimming, Naxos is one of the safest choices in the Cyclades: Agios Georgios, Agios Prokopios, Agia Anna, Plaka. Western Crete has Balos, Elafonisi and Falasarna, with long distances between them. Lefkada has Porto Katsiki and Egremni, but you need a car and patience for winding roads. Milos is more photogenic and more geological: Sarakiniko, Kleftiko, Firiplaka, Tsigrado.

🏛️ If you want history
Crete has Knossos, Phaistos, Venetian Chania and Rethymno, museums and villages with living traditions. Rhodes has the medieval Old Town, a UNESCO World Heritage Site, with the Knights of St John, Lindos and Kameiros. From Mykonos you can visit Delos, one of the most important sanctuaries of the ancient world. Patmos has a different feel: a monastery, the Chora, the Cave of the Apocalypse and a quiet pace.

🥾 If you want to walk
Crete is the strongest choice: Samaria, the White Mountains, Psiloritis, gorges and villages. Naxos has Mount Zas, the highest peak in the Cyclades, and footpaths between the mountain villages. Amorgos, Tilos and Karpathos have footpaths with fewer people. In July and August walk early in the morning: midday in the Cyclades, with no shade, is harsh.

🎉 If you want nightlife
Mykonos is the expensive version: beach bars in the south, clubs, reservations and bills that climb fast. Ios is younger and cheaper. Paros, mainly Naousa, has gentler evenings, with drinks at the little harbour rather than clubbing till dawn. If you want quiet evenings, avoid Mykonos, Ios and central Naousa in August.

👨👩👧 If you are travelling with children
Naxos and Paros work well for families: shallow sandy beaches and fairly simple journeys. Crete has infrastructure, hospitals, big hotels and options in any weather. Aegina and Poros are practical for a short trip from Athens. Hydra is hard with a pushchair, because of its steps and cobbles, and the caldera villages on Santorini tire small children.

💶 If budget matters
On a tighter budget, look at Aegina, Naxos off-season, Ikaria and Karpathos. On a mid-range budget, Paros, Milos, Crete, Rhodes and Kefalonia have plenty of options, as long as you book early. Mykonos, Santorini, Hydra and Spetses climb fast: there, changing the month helps more than endless searching.
🌿 If you want something different
If you have already seen the famous ones, look beyond the Cyclades. The Ionian has green mountains down to the sea and Venetian towns, such as Corfu. The North Aegean has big, authentic islands with less tourism, such as Ikaria. The small Dodecanese islands, such as Symi and Tilos, have colourful harbours and peace. See also our guide to the lesser-known islands worth the detour.

🗓️ Month by month
April and May are good for walking, archaeological sites and towns, with the sea still cool. June is one of the most balanced months. July and August mean high prices, crowds and the meltemi in the Aegean. September has a warm sea and a better pace. October often keeps swimming going until mid-month. From November to March, Crete, Rhodes and Corfu suit best, as they are alive all year round.
🧭 Four ready-made plans
Classic Cyclades
Santorini for 2–3 nights and Naxos for 2–3 nights. A little spectacle and a little everyday island life.
Beach and culture
Crete, with Heraklion, Knossos and Chania. Don’t try to see the whole island.
Quieter Cyclades
Milos and Folegandros, with careful checking of ferries. Santorini goes at the end only if there is a good connection.
No long ferry
Athens as your base: one day on Hydra, one on Aegina, one in the city. More relaxing than island hopping.
To combine islands, see our tips for island hopping. For the ferries, see our guide to ferries from Piraeus.
⚠️ Common mistakes
- Too many islands. One island every 3–4 days is already enough.
- Santorini and Mykonos as the whole of Greece. They show two extremes, not the full picture.
- August without a booking. Rooms, ferries and cars sell out.
- Choosing only by the cheapest ferry. A bad connection costs more.
- Ignoring the meltemi. In the Cyclades it changes both the beach and the ferry schedule.
If you will only make one trip to the Greek islands, choose Crete or the Santorini and Naxos combination. For a short break from Athens, Hydra for atmosphere or Aegina for ease. If you have already seen the famous ones, look at the Small Cyclades, Karpathos, Tilos, Patmos, Symi or Ithaca.
Frequently asked questions
What is the best island for a first visit?
Naxos, for its balance, or Crete, if you want variety on one island. Both have beaches, history, food and good connections.
Which island is closest to Athens?
Aegina, about 40 minutes by fast ferry from Piraeus. From Ioulianou 50, take Line 1 from Victoria to Piraeus.
Which island has the best beaches?
For sandy beaches, Naxos and western Crete. For unusual, geological landscapes, Milos. For turquoise water below cliffs, Lefkada.
Which island should I choose in winter?
Crete, Rhodes or Corfu, which have towns and life all year round. The small Cycladic islands close almost completely.
Santorini or Mykonos?
Santorini for the caldera, sunsets, wine and ancient sites. Mykonos for beaches, nightlife and Delos. If you want a bit of both without the excess, Naxos sits in between.
