Greece has far more inhabited islands than any trip can sensibly cover, and they differ more than the postcards suggest. Some are built for nightlife, some for walking, some for doing very little in a village with three tavernas. Choosing badly is the main way people come home disappointed.
Groups, in short
The Cyclades give you the whitewashed look, good ferry links and the biggest crowds. The Dodecanese, further east, mix medieval towns with quieter beaches. The Ionian islands to the west are greener and often reached from different airports. The smaller, less connected islands trade convenience for calm.
Ferries and logistics
Ferry schedules dictate itineraries, and they thin dramatically outside summer. Two islands in a week is comfortable, three is busy, four is a travel diary rather than a holiday. Check whether a connection actually exists rather than assuming neighbouring islands are linked, since many route through a hub.
- High-speed ferries cost more and cancel more readily in wind
- Build a spare night before an international flight home
- Small islands may have limited cash machines, so arrive with some cash
When to go
May, June, September and early October give warm sea and manageable crowds. Midsummer is hot and full, and August is when Greeks holiday too. By late autumn many island businesses close for the season, which is peaceful but limiting.
Eating and customs
Dinner starts late and is not rushed; asking for the bill is on you. Ordering a few shared dishes is the normal pattern. Tipping is modest, rounding up or leaving a small amount. In villages, a greeting when you walk into a shop or taverna is standard courtesy.
What to skip
Day trips that put you on a boat for six hours to spend forty minutes on another island. Stay put, swim, and eat lunch slowly instead.
