Getting around Greece: trains, buses, driving and domestic flights

Match the mode to the shape of your trip, not to a single rule. A Cyclades chain of two or three islands is a ferry job. Crete, Rhodes, Corfu or Thessaloniki are flight jobs from Athens. The mainland — Delphi, Nafplio, Meteora, Patras — is bus and train country. A car earns its cost only where you want to stop between villages, which means Crete, the Peloponnese or one large island.

Book the long legs first. In summer, Piraeus–Cyclades ferries and Crete cabins fill weeks ahead; domestic flights on Aegean, Olympic and Sky Express are cheapest booked early. Then fill the middle with buses and trains, which rarely need booking more than a day or two out.

At Piraeus, check which gate your ship uses (E1–E12) before you leave the metro, and arrive 30–60 minutes early. On conventional ferries, deck space never sells out, so a last-minute ticket is usually possible even in August.

For the mainland, KTEL runs the intercity buses. Athens has two main stations, Kifissos and Liossion, and they serve different routes — confirm which one before you set off. Trains are the comfortable choice on the Athens–Thessaloniki line; elsewhere the network is thin, and post-2023 upgrade work can mean delays and bus substitutions, so check before you travel.

If you hire a car, sort the paperwork at home. Non-EU licences need an International Driving Permit in Greece. Ferries charge extra to carry a car, island roads are narrow, and parking in Athens and Thessaloniki is its own project — pick up the car on the day you leave the city.

The meltemi wind is the single biggest variable in Aegean travel from roughly July to August. Small high-speed craft are cancelled first and roll badly in swell; conventional ferries are slower but far more reliable. If a tight connection matters, build in a spare day or fly.

Almost all island-to-island flights route through Athens, so a flight is rarely a shortcut between two islands. Ferries connect islands directly, but not every pair, and not every day.

Quads and scooters look easy and are not: accidents are common on island roads, insurance often excludes quad damage, and a motorbike licence is required. If you do not already ride, do not start here.

Tap water is safe in Athens, Thessaloniki and most of the mainland; on many islands it is desalinated or hard, so ask locally and buy bottled if unsure. Carry cash for small ferries, buses and kiosks.
