Crete: plan a longer stay
This is not a day-trip from Athens. It is the largest Greek island — mountains, a long north-coast road, and south-coast pockets that repay a car or a slow bus.
What it is for
- One-island holidays instead of four rushed ports.
- Split bases (e.g. Chania and Heraklion areas) if you accept transfer time.
- Archaeology (Knossos is the famous name; it is not the whole island).
Air and sea
Airports: HER (Heraklion) and CHQ (Chania). See getting here. Ferries from Piraeus run to Cretan ports — check operator (Blue Star / Attica Group are the names you will see most; still verify the ship).
KTEL on the island is useful along the north coast. Regional booking examples exist (e.g. e-ktel.com for Chania–Rethymno). I will not invent a Chania–Heraklion duration.
