Best places to visit in Greece
Athens
Start with the Acropolis, major museums and neighbourhoods such as Plaka and Monastiraki.
Greek islands
Santorini and Mykonos suit iconic Cycladic scenery, while Crete, Rhodes and Corfu support longer trips with beaches, historic towns and road-trip options.
Meteora and the Peloponnese
Visit Meteora for monasteries and dramatic rock landscapes, or combine Nafplio with Mycenae and other ancient sites.
When to visit Greece
Spring and autumn usually provide the best balance of warm weather and manageable crowds. Summer is ideal for beaches and island hopping but is hotter, busier and more expensive. Winter is better for Athens, Thessaloniki and mountain travel.
Getting around
Use domestic flights and ferries for island travel, urban public transport in Athens and Thessaloniki, and rental cars for larger islands and rural routes. Allow buffers around ferry connections.
Mobile data in Greece
Reliable data is useful for ferry updates, maps, accommodation messages, tickets and translation. A typical one-week trip may need 5–10 GB; island hopping, video and hotspot use can justify 10–20 GB or unlimited data.
