Decide whether you need a car for the whole trip
Begin with the places you want to visit, not the rental listings. Mark your accommodation, arrival point, beaches, walking routes and villages on a map. If most of your plans are close together, a car for just one or two days may be more useful than a week-long booking. Buses, boats, bicycles and walking can also be enjoyable parts of an island journey, although their schedules and suitability vary.
Consider where a car would sit when you are not using it. Parking may be limited near old town centres, harbours and popular beaches, and your accommodation may not include a space. Ask about parking before booking, especially if you plan to stay on a narrow lane or in a pedestrian area. A smaller car is often easier to place on tight roads, provided it has enough room for your passengers and luggage.
Match the vehicle to the roads
An island can have several kinds of driving in a small area: smooth main roads, steep village streets, sharp bends or rough tracks leading towards a viewpoint. Look closely at the routes you expect to take and ask your accommodation or rental company about any difficult approaches. A car that seems convenient at the airport may feel less suitable on a narrow road with little room to pass.
Check the transmission type, seating and luggage capacity rather than relying on the vehicle photo alone; rental companies may supply a similar model instead. If you are considering a larger vehicle for comfort, balance that against the roads and parking you expect to encounter. Do not assume that an ordinary rental agreement permits driving on unpaved tracks, even if a route appears on a map.
Read the rental terms before comparing prices
Compare the full cost, not just the daily rate. Check what is included for additional drivers, mileage, child seats, roadside assistance and pickup outside normal hours. Note the fuel or charging policy and the amount held as a deposit. If your arrival depends on a flight or ferry, find out what happens if you reach the desk later than planned and how to contact the company.
Read the insurance and damage terms carefully, including the excess and any exclusions for tyres, glass, the underside of the car or lost keys. Requirements and cover differ between providers and locations, so ask for clarification if a term is unclear. Before you pay, confirm the licence and payment-card requirements for every person who may drive.
Check ferries and island-to-island travel separately
Do not assume a rental car can leave the island where you collect it. Some companies restrict ferry travel, require advance permission or have different arrangements for breakdowns away from the pickup island. If your itinerary includes another island, ask the company to confirm its policy for the specific route and vehicle before making a non-refundable booking.
Taking the car on a ferry also adds another timetable and cost to your plans. Compare that option with travelling as a foot passenger and renting a second vehicle only if you need one. This can be simpler when you want to spend most of the next island visit in a harbour town or on walking trails.
Plan the pickup and your first drive
Find the exact pickup location: an airport desk, a shuttle stop and a harbour office are very different after a long journey. Check opening hours and allow time to reach your accommodation without rushing. If possible, plan a straightforward first drive in daylight, leaving more demanding roads until you are familiar with the car and local signs.
At pickup, inspect the vehicle with the agent when possible and make sure existing marks are recorded. Check the fuel level, lights, tyres and the location of any charging cable or safety equipment supplied. Save the rental company’s contact details somewhere you can reach offline. A few careful checks at the start leave you freer to slow down, stop where parking is permitted and enjoy the journey beyond the arrival port.
