Car Hire in Greece: What to Know Before You Book

Greece is not one driving destination but two, and the booking decision is different for each. On the mainland and the larger islands a hire car is the difference between seeing three villages and seeing thirty. On a small island, or on a trip that hops between several, it can be an expensive way to move a vehicle you barely use. Settle which trip you are taking before you book, because the answer changes the car, the pick-up point and the price. For the underlying method, start with how to rent a car abroad without overpaying.

Island-hopping changes the question entirely

The instinct on a multi-island trip is to hire one car at the point of arrival and take it along. In practice the cheaper and simpler pattern is almost always the opposite: travel between islands as a foot passenger and hire a separate car on each island where you actually want one. You pay for a vehicle only on the days it earns its place, you skip the vehicle fare on every crossing, and you avoid the paperwork entirely.

It also protects you from the trip's most common piece of bad luck. Ferry schedules in Greece are subject to weather, and a cancelled or rescheduled sailing is an ordinary event rather than a disaster. Without a car aboard, a missed crossing costs you a day. With one, it can also mean a rental agreement that no longer matches where the car physically is, and a return branch you cannot reach on time.

Taking a hire car on a ferry

If you do want the same car on more than one island, treat it as something to be agreed in writing before you book, not assumed. Many suppliers require prior permission to take a vehicle on a ferry, and some prohibit it outright — a restriction that sits in the rental conditions rather than on the booking page, which is why travellers discover it at the desk. Ask the specific question, get the specific answer, and check what it does to the cover on the car while it is aboard.

The same caution applies to collecting a car on one island and dropping it on another. Where a supplier permits it at all, it is a one-way rental across a water gap and is priced accordingly. Our one-way car hire guide covers how those charges are built and when they are worth paying.

The roads, and the car to book for them

• Book the smallest car that genuinely carries your luggage — village lanes, port towns and older parking areas were not built for a large vehicle, and a big car turns tight streets into a daily problem.
• Most of the fleet is manual. Automatics exist but are a minority, and on the islands a small one, so book early and build the rest of the trip around that constraint.
• Rural and mountain roads can be narrow, unlit and steep, with surfaces that vary; plan journey times on the map's shape rather than its distances.
• Check the supplier's conditions on unsurfaced roads. Many exclude damage sustained off sealed roads, which matters if a beach or a taverna sits at the end of a dirt track.

That last point is worth dwelling on, because it is the clause most likely to turn a good trip into an argument. A track down to a remote beach is exactly the sort of place a hire car is wanted, and exactly the sort of place the rental conditions may not cover it. Read the wording before you decide the trip depends on reaching somewhere only a track serves.

Tolls, fuel and parking

The main mainland motorways are tolled, and the tolls are collected at barriers you pass through rather than by a ticket taken at one end and paid at the other. Card and cash lanes sit alongside lanes reserved for transponder holders; use the general lanes unless the car came with a device and the supplier has told you how the charges reach you. If a car does carry a transponder, ask at the desk how usage is billed and what is added for handling it, because that is where the cost sits.

Fuel is generally served by an attendant rather than at self-service pumps, so state the fuel type and the amount, and confirm the pump is zeroed before it starts. Take a full-to-full policy and fill up before returning the car, ideally at a station away from the airport perimeter. Away from the main towns, opening hours can be shorter than you expect and stations thinner on the ground than a map suggests, so treat a half tank on a rural evening as the point to refuel rather than a comfortable margin.

Parking in the older parts of towns is the recurring friction. Streets are narrow, marked bays are few, and the practical answer is usually a car park on the edge of the centre followed by a walk in. Ask the hotel where its guests actually park before you arrive, rather than circling with the luggage still in the car.

Season decides the price, and the fleet

Greek car hire is intensely seasonal, and island fleets are finite in a way mainland fleets are not. Through the peak summer weeks the small and automatic classes are the first to disappear on the islands, and what remains is priced accordingly. The defence is the one that works everywhere: book early on a free-cancellation rate, then re-shop as the dates approach and rebook if the price has moved in your favour.

Shoulder season is where Greece becomes both cheaper and better to drive. The roads are quieter, the fleet is not picked over, and the parking problem in the pretty places largely solves itself. If the dates are yours to choose, they are the strongest lever you have on the total cost.

Where a car earns its keep, and where it does not

On the mainland — the Peloponnese, Epirus, the routes out to Meteora and the Mani — a car is transformative and there is no realistic substitute for one. On a large island with real distances, the same holds. On a small island where the settlements sit within a few kilometres of each other, a car spends most of the week parked while you pay for it, and buses, taxis or a scooter cover the trip more cheaply.

Athens is the clear case against. Traffic is heavy, parking is scarce and expensive, and the metro reaches most of what a visitor wants. The better-shaped Greek trip usually collects the car on leaving the city and returns it on arriving back, which also removes several days of parking charges from the bill. If your trip is the island comparison rather than the mainland drive, Santorini versus Mykonos is the more useful place to start.

Before you sign at the desk

• Decide your excess cover before you travel, not at the counter where it is sold under time pressure — see car rental insurance explained.
• Photograph the car from every angle, including roof, wheels and windscreen, before you drive away and again on return.
• Confirm the fuel policy on the agreement matches the one you booked, and that the tank is as full as the paperwork claims.
• Whether you need an International Driving Permit alongside your national licence depends on the country that issued your licence — check your own government's guidance rather than the rental company's.
• Ask which charges can reach you after the rental ends, and how — that is where the surprises live, as avoid hidden car rental fees sets out.

Getting the best rate

Prices at Greek airports and island depots vary widely between suppliers for the same car on the same dates, so comparing across suppliers matters more here than picking a brand you recognise. Compare car hire in Greece on DiscoverCars, check the reviews for the specific pick-up location rather than the company as a whole, and hold a full-to-full, free-cancellation rate you can re-shop later.
