Greek Island Ferries vs Flights: When to Take Which

Greece’s ferry network is extensive, cheap and genuinely pleasant. It’s also slow, weather-dependent, and the reason a lot of island-hopping itineraries fall apart. Knowing when to fly instead is the difference between a relaxed trip and a stressful one.

Typical journey times

The rule: fly from Athens to your first island, then ferry between islands within the group.

Ferry types

• Conventional ferries — larger, slower, cheaper, far more stable in rough seas. Take these if anyone gets seasick.
• High-speed catamarans — roughly half the time, roughly double the price, and cancelled more readily in high winds.

In strong Meltemi conditions, high-speed services are the first to be pulled while conventional ferries keep running.

The three things that catch people out

1. Cancellations. Ferries stop in high winds, most often July and August. There’s no appeal and no alternative — you wait. Never book a ferry that arrives the same day as an international flight.

2. Summer sell-outs. Popular routes sell out days ahead in August, especially with a vehicle. Book as soon as your dates are fixed.

3. Ports aren’t in towns. Piraeus is a 40-minute metro from central Athens, and island ports can be a long way from where you’re staying. Add an hour at each end.

Booking notes

• Reserved seating is worth the small extra on journeys over two hours.
• Deck class is fine in good weather and much cheaper.
• Check the operator’s cancellation policy — refunds for weather cancellations vary.
• Domestic flights from Athens are frequently €40–80 if booked ahead.
