Renting a Car in Greece: Everything You Need to Know Before You Book

Renting a car in Greece is straightforward for most visitors, but a few local rules catch people out. You need a valid driving licence, a credit card in the main driver's name for the security deposit, and often an International Driving Permit (IDP) if your licence was issued outside the EU or EEA. Book early for summer and reserve an automatic specifically if you can't drive a manual, because stick-shift cars dominate the Greek fleet and automatics sell out fast between May and September.

Greece rewards drivers with freedom the ferries and buses can't match, especially once you're off the main routes. The golden rule for island hopping: rent a fresh car on each island rather than paying to take one car across on the ferry. It's almost always cheaper and far less hassle. Below is everything to sort out before you book, so the only surprise on the road is the view.

Licence and International Driving Permit rules

What you need depends on where your licence was issued. EU and EEA licences are valid in Greece exactly as they are. If your licence comes from outside the EU/EEA, Greek law and most rental agencies expect you to carry an International Driving Permit together with your original national licence — the IDP is a translation, not a replacement, so you must have both on you. An IDP is cheap and quick to get from your home country's motoring authority before you leave, and you can't usually get one once you've arrived.

Rules and enforcement can change, and some agencies are stricter than the legal minimum. Always confirm the exact requirement with your rental agency or the relevant Greek authority before booking, rather than assuming your licence alone will be enough at the counter.

Age, documents and payment

Most agencies rent to drivers aged 21 and over, though larger, premium or high-powered cars often require you to be 23 or 25. Drivers under 25 should expect a young-driver surcharge. You'll typically also need to have held your licence for at least a year.

At pick-up, bring your licence (plus IDP if required), your passport or ID, your booking confirmation, and — this is the one people forget — a credit card in the main driver's name. The agency blocks a security deposit on that card to cover excess and incidentals. Debit cards and cash are often refused for the deposit, so check the accepted payment methods when you book.

Deposit, mileage and fuel policy

Before you confirm, read three things: the deposit amount, the mileage allowance, and the fuel policy. A fair deal is unlimited mileage and a simple fuel-to-fuel (also called full-to-full) policy — you collect the car full and return it full. Avoid 'full-to-empty' style policies where you pre-pay for a tank and lose whatever fuel you don't burn. Knowing the deposit figure in advance also means no shock hold on your card at the counter.

• Deposit: how much is blocked, and when it's released after return.
• Mileage: unlimited is ideal; otherwise check the per-kilometre charge.
• Fuel: fuel-to-fuel is the fairest; note the nearest station to the drop-off point.
• Insurance and excess: what's covered, and the deductible you'd pay on a claim.

Manual vs automatic — reserve early

Greek rental fleets are predominantly manual. If you can only drive an automatic, treat it as a scarce item: reserve it as early as you can, because in summer the automatics are often gone first. Expect to pay more for one, and don't rely on being able to switch at the desk — confirm the transmission on your actual booking.

Peak season pricing and booking early

Demand climbs steeply from May through September, and on popular islands the fleets are finite — once the local cars are booked, there simply aren't more. Prices rise and the cheaper categories disappear first. The single best money-saver is booking weeks ahead rather than days. Last-minute summer rentals, especially automatics on small islands, can be eye-wateringly expensive or unavailable entirely.

Islands vs mainland: don't ferry one car around

Taking a rental car on a ferry between islands usually costs more than it's worth: you pay for the vehicle's ferry ticket, you burn hours of your rental on boats instead of roads, and many agencies restrict or forbid taking their car off the island. The cleaner approach is to rent locally on each island you stop at and go car-free on the ferry. You also get a car sized to the island — a compact for tight village lanes rather than whatever you picked up on the mainland.

Driving in Athens vs the islands

Athens is a busy capital: dense traffic, assertive drivers, scooters weaving between lanes, and parking that takes patience. Many visitors skip a car entirely in central Athens and rent only when they leave the city. The islands are the opposite — quieter roads, but often narrow, winding, steep and sometimes unpaved, with livestock and oncoming cars around blind bends. Drive calmly, use your horn lightly on blind corners as locals do, and don't rush.

Colour-coded street parking in cities

In Athens and other larger towns, kerbside parking is often colour-coded. As a general guide, blue lines mean paid, controlled parking (buy a ticket or use the app), white can indicate free or resident parking, and yellow typically marks no-parking zones, loading bays or bus stops. Codes and enforcement vary by municipality, so read the nearest sign and, when in doubt, use a paid car park — a tow or fine will cost far more than the parking fee.

What transparent booking looks like

Most of the stress in renting a car comes from not knowing the real number until you're at the counter — the deposit, the fees, what the insurance actually covers. A transparent marketplace fixes that. DRIVO, for example, is a European marketplace where you rent directly from trusted independent and local agencies across Europe and North Africa, with both the rental price and DRIVO's own service fee shown up front before you pay. You see the security deposit and exactly what the agency's insurance covers before you book — insurance is arranged directly with the agency under its own terms, not an add-on DRIVO sells. You get instant confirmation and free cancellation up to 48 hours before pick-up, with the service fee refunded too, so reserving early carries no penalty if plans change. Listings and support come in five languages (English, French, Spanish, Italian and Arabic), with WhatsApp and in-app concierge help if you have a question before you drive off. Whatever platform you book your Greek car through, look for that same up-front pricing, a clear deposit figure, and insurance terms you can read before you commit.
