Rent a Car Kos: Your Complete Guide to Exploring the Island Like a Local
If you have never rented a car on a Greek island before, the process is straightforward but there are a few things worth knowing. Renting a car in Kos is not complicated, but spending ten minutes reading this will save you an hour of confusion later.
This guide walks through the whole process from booking to drop-off, with the practical details that actually matter and the ones you can safely ignore.
Step One: Book Before You Arrive
Kos is busy in summer. The small cars sell out first, and the prices increase as availability drops. Book two or three weeks ahead if you can. Same-day rentals are possible outside July and August, but do not count on them.
Use the search tool on koscarhire.com. Enter your dates, choose a car, and confirm. You will receive a voucher with the office location, opening hours, and what to bring.
Step Two: Documents You Actually Need
Bring your driving licence, your passport, and the credit card used for the deposit. Photocopies are not accepted. If your licence is not in English or Greek, an International Driving Permit is advisable, though many offices will accept a standard licence with a translation app ready.
The minimum age is usually twenty-one, though some categories require the driver to be twenty-five.
Step Three: Collecting Your Car
You can collect either at Kos Airport or in Kos Town. Both are simple, so pick whichever fits your arrival.
At the desk, the staff will verify your documents, take the deposit, and walk you to the car. Check the fuel level — the car should be full — and note any existing scratches or marks. Take photos. It takes two minutes and saves arguments later.
Ask where the nearest petrol station is and how to open the fuel cap. Different cars hide the release lever in different places, and fumbling around at a Greek petrol station is not how you want to spend your first evening.
Step Four: Driving on Kos
Roads are generally good, though the mountain routes can be narrow and occasionally shared with goats. Signposting is fine in the towns and patchy in the countryside. Download an offline map before you leave your hotel.
Parking in Kos Town is manageable in May and September. In July and August, arrive early or expect to walk. The beaches fill by eleven in the morning, even the ones with parking lots.
Drive on the right. Speed limits are enforced, particularly near the airport. Seatbelts are compulsory and the fines are real, not theoretical.
Step Five: Returning the Car
Return the car to the same location where you collected it. Fill the tank before you arrive. The return process is quick: a visual inspection, a signature, and you are done.
If your flight is very early or very late, check whether the office supports out-of-hours returns. Not all do.
How Much Should You Expect to Pay?
Our cheapest category starts at €25 per day. Mid-size cars are more, and SUVs cost more again. See our cheap car rental Kos page for the current rates.
The total cost depends on how long you rent, which category you choose, and whether you are visiting in peak season. A compact car for a week in June will cost significantly less than the same car in August.
What Type of Car Do You Actually Need?
Couples and solo travellers: compact is fine. Families: mid-size. Large groups: people carrier or SUV.
You do not need four-wheel drive. Kos roads are paved and the hills are gentle. The only time a larger car helps is when you are carrying luggage for more than two people.
Final Tips
Book early, fill the tank before return, and check the car before you leave the lot. The rest is just driving around a beautiful island.
