Same 0 to 100 rating as the strip above, from each city's own long-run normals.
Where you go changes when you go
Athens and the mainland
Hot summers and mild winters. Spring and autumn are ideal for the Acropolis and ancient sites, without the summer heat.
The Cyclades and islands
Santorini, Mykonos and the rest are at their best from May to mid June and late August into September, warm but a touch calmer.
Crete and the south
The warmest, longest season of all, with swimming well into October and mild winters.
Athens, Meteora and down the Cyclades to Crete
A few days in Athens, a train north to the monasteries at Meteora, then ferries south through the Cyclades to Santorini and on to Crete. Late May, June and September are the sweet spot: ferries running, sea warm, crowds thin.
Lines show the order of stops, not the roads or ferry tracks.
Athens
The Acropolis, Plaka and Psyrri. Base for the train north and the ferries south.
Nafplio
A Venetian harbour town, with Epidaurus and Mycenae close by.
Meteora
Monasteries on rock pillars. One full day covers the main ones; cover shoulders and knees.
- Train back, then the ferry from Piraeus
Paros
Naoussa harbour, Parikia and the beaches in between. A sociable hub island.
Naxos
The biggest Cycladic island: long beaches, hill villages, and the best value of the group.
Milos
Volcanic coves and the moonscape at Sarakiniko. Rent a scooter.
Santorini
The caldera, Oia at sunset and the Fira to Oia walk. Two nights is plenty.
Heraklion, Crete
Knossos, the old harbour, then Chania or the Samaria gorge. Fly home from Heraklion.
Chania
The prettiest harbour in Crete, and the base for the Samaria gorge and Balos.
