Greece has the longest coastline on the Mediterranean and somewhere between 1,200 and 6,000 islands depending on how an island is counted, of which 227 are inhabited. That figure is the whole planning problem. Around 10 million people live in the country's nine regions, and the three largest cities - Athens, Thessaloniki, Patras - are all on the mainland, while the 21 UNESCO World Heritage Sites are spread across mainland and islands alike. Most trips split accordingly: the mainland for antiquity and the mountains that fill the southern tip of the Balkan peninsula, the islands for the sea, with Crete, the largest of them, big enough to fill a week on its own.

Common questions

How long should a first trip to Greece be?

Eight to twelve days can cover Athens, one mainland archaeological route and one island group. Every ferry leg consumes real itinerary time, so collecting ports across several island chains is poor use of a first visit.

What entry documents are needed for Greece?

Greece’s Ministry of Foreign Affairs provides the visa framework for entry. Passport nationality, stay length and the wider Schengen route determine whether an application is needed and where it must be lodged.

What is the best way to travel around Greece?

Athens is the main gateway, while ferries and domestic flights connect island groups and regional airports. Mainland buses and limited rail corridors require route-specific planning; ferry schedules should be rechecked close to travel.

When is a practical time to visit Greece?

April to June and September to October suit many archaeological and island itineraries without peak midsummer heat. Ferry exposure, island seasonality and mountain weather still vary by destination.

What money and payment basics apply in Greece?

Greece prices transactions in euros (EUR). National card-acceptance and fee details are Not recorded in this bundle; confirm payment expectations with small accommodations, boat operators and remote businesses.

What practical safety details should I save for Greece?

Greece uses 112 for emergency assistance and 230 V Type C and F sockets. A single nationwide tap-water recommendation is Not recorded, so use the relevant island or municipal guidance.
