Greece has around 200 inhabited islands in six groups. The useful question isn’t which is “best” but which group suits your trip — because moving between groups eats days.

The groups
| Group | Character | Best for |
|---|---|---|
| Cyclades | White villages, blue domes, dry and dramatic | First visit, the classic image |
| Ionian | Green, sheltered, Italian-influenced | Families, sailing, calmer seas |
| Dodecanese | Medieval towns, Turkish influence | History, fewer crowds |
| Crete | Its own world — mountains, gorges, cities | Two weeks, road trips |
| Sporades | Pine forests, clear water | Quiet, greenery |
| Saronic | Close to Athens | Short trips, weekends |
Pick one group per trip. The Cyclades and the Ionian are on opposite coasts and connecting them means going back through Athens.
The Cyclades, island by island
| Island | Character | Cost |
|---|---|---|
| Santorini | The caldera. Spectacular, crowded | High |
| Mykonos | Nightlife, beach clubs, glamour | Highest |
| Naxos | Big, green, great food and beaches | Moderate |
| Paros | Pretty towns, good balance | Moderate |
| Milos | Extraordinary coastline, quieter | Moderate |
| Folegandros | Tiny, dramatic, barely developed | Moderate |
The usual mistake is booking Santorini and Mykonos together — the two most expensive and most crowded islands, and quite similar in how they feel in August. Pair one famous island with one quiet one instead.
The Ionian
Greener, wetter, and much more sheltered — which is why it’s the beginner’s sailing region. Corfu for variety and history, Kefalonia for scenery, Zakynthos for beaches, Lefkada because you can drive to it.
If you’re chartering rather than staying ashore, this is where to start — see sailing the Greek islands.
How many islands?
Two in ten days. Three at most. Ferries between Cycladic islands take 30 minutes to 3 hours, run to fixed schedules, and cancel in high winds. Each hop costs half a day.

Frequently asked questions
How many Greek islands should I visit?
Two in ten days, three at most. Ferries between islands take 30 minutes to 3 hours and each hop costs half a day.
Which island group is best for a first visit?
The Cyclades — Santorini, Naxos, Paros and Milos. It’s the classic white-village image most people have in mind.
Which islands are best for families?
The Ionian — Corfu, Kefalonia and Lefkada. Calmer seas, shallower beaches and greener landscapes.
Can I combine the Cyclades and the Ionian?
Not sensibly in under two weeks. They’re on opposite coasts and connecting them means routing back through Athens.
About the author
Born and raised in the Middle East, I’ve spent most of my adult life travelling — more than 40 countries so far. I write these guides the way I’d explain them to a friend: real prices, honest opinions, and a straight answer when the cheaper option is the better one. I don’t sell tours or own hotels, which is why I can tell you what the operators won’t.
