The capital
Athens is where most trips begin: the Acropolis and world class museums above a lively modern city of tavernas, markets and rooftop bars. Its ports at Piraeus and Rafina are the gateways to the islands.
The Cyclades
Santorini is the famous volcanic island, with white villages on the rim of a sea filled crater and sunsets that draw crowds every evening. Naxos, a short ferry ride away, is bigger, greener and calmer, with long sandy beaches, mountain villages and excellent farm food. The two pair perfectly.
The big island
Crete is a world of its own: the Minoan palace of Knossos, Chania's Venetian harbour, the Samaria Gorge, pink sand at Elafonisi and some of the best food in Greece. Give it at least five days.
The mainland
Meteora is one of Europe's most extraordinary sights, with Byzantine monasteries perched on top of giant rock pillars in Thessaly. Thessaloniki, the second city, is a relaxed seafront port with Byzantine churches, a big student scene and a reputation as the country's food capital.
How to link them
A classic ten day route is Athens, Santorini and Naxos by ferry, then back to Athens. With two weeks, add Crete by ferry or flight from Santorini, or swap the islands for the mainland: Athens to Meteora by train, then on to Thessaloniki and fly home from there.
