Car Hire in Portugal: What to Know Before You Book

Portugal is one of the easier countries in Europe to drive: the distances are short, the motorways are good, and the coast and the interior both reward getting out of the cities. It also has one charge that catches more visitors than any other, and it is not a fine — it is the way some of its motorways collect tolls. Understand that before you book and the rest of the trip is straightforward. For the general booking discipline, start with how to rent a car abroad without overpaying.

Electronic tolls — the one that catches everyone

Some Portuguese motorways have no toll booths at all. There is nowhere to stop, nowhere to hand over a card and no barrier — an overhead gantry reads the number plate as you pass and the charge is raised against the vehicle afterwards. Drivers used to taking a ticket at one end and paying at the other reach their destination assuming the road was free, and learn otherwise only when the bill appears through the rental company later.

The practical consequence is that you must know, before you drive away, how the car you have hired is set up to pay. Most suppliers offer some form of electronic device or plate registration, either included or as a daily-rate add-on, and each has its own way of passing the toll charges on together with an administration element. The question to ask at the desk is not whether the car has a device, but three things about it: how you can tell it is active, how the tolls themselves will be billed to you, and what is added on top for handling them.

Two things follow. First, get the answer written onto the rental agreement rather than given verbally, because the charge lands weeks after you have gone home and the conversation at the desk is no longer available to either of you. Second, if you decline the device you have not avoided the tolls — you have only changed who settles them and how, and settling them yourself as a visitor in a rental car is more awkward than it sounds. For most travellers on a short trip, taking the supplier's arrangement and reading the terms is the calmer choice.

The older toll roads with conventional barriers still exist alongside the electronic ones, so a single journey can involve both. There are also toll-free national roads running roughly parallel to several motorways. They are slower and pass through towns, which on a holiday is frequently the better drive rather than the compromise — but choose them deliberately, not by accident.

The cities are the wrong place for the car

Lisbon and Porto are both built on hills, with narrow historic streets, tram lines, steep gradients and very limited parking. Both have public transport good enough that a visitor does not need a car, and both make one an active nuisance to keep. The well-shaped Portuguese trip usually starts and ends in a city without a car and collects the vehicle for the stretch in between, which removes several days of city parking from the bill at the same time.

Where you do end up parked overnight in a city, a secure car park is worth the cost over an on-street space, particularly with luggage in the vehicle. Ask the hotel what its guests actually use rather than trusting a map. If you are still choosing where to base yourself, our Lisbon guide and Algarve guide cover the two ends of that decision.

The car to book

• Small wins again. Historic centres, hill towns and older car parks all favour a compact vehicle, and nothing about a larger car improves a Portuguese road trip.
• Manual transmission dominates the fleet. If you need an automatic, book it early and treat it as the fixed point of the itinerary.
• Take a full-to-full fuel policy and refuel away from the airport perimeter before returning the car.
• Check the conditions on unsurfaced roads before planning a route that depends on one, and on taking the car out of the country if Spain is part of the trip.

That last item matters more than it looks. The Algarve and Andalusia sit close enough together that a combined trip is a natural idea, and crossing a land border in a hire car is usually permitted — but usually is not always, and some suppliers restrict it or charge for it. Confirm it before you build the itinerary around it, and see car hire in Spain for the other half of that drive.

Parking, fuel and the details that cost money

On-street parking in town centres is generally paid during the working day through a machine or an app, with the ticket displayed on the dashboard, and free outside those hours — but the hours are posted locally rather than set nationally, so read the sign at the head of the row instead of assuming the pattern from the last town. In the busier coastal resorts through the summer, a paid car park is often the only realistic option near the beach, and arriving early is worth more than circling.

Filling stations are plentiful along the motorways and thinner in the interior, where opening hours are shorter and an unattended automatic pump may be the only option late in the evening. That is a poor moment to find out whether a machine accepts your card, so refuel in daylight when the interior is on the route.

Madeira and the Azores are separate decisions

The islands are their own rentals, hired locally rather than taken from the mainland, and the case for a car is strong on both — the interiors are the reason to go and public transport does not reach most of it. Book early, because island fleets are small and the peak weeks empty them, and expect steep, winding and sometimes narrow roads that make a small car and an unhurried schedule the sensible combination. The best-known walks and viewpoints tend to end at car parks that fill in the morning.

When to book

Coastal demand concentrates hard into the summer, and it is again the small and automatic classes that go first. Book those windows as early as you can on a free-cancellation rate, then re-shop and rebook if the price falls. Outside the peak, Portugal is one of the cheaper countries in western Europe in which to hire a car, and the driving is better without the season's traffic.

Before you sign at the desk

• Settle your excess cover before you travel rather than at the counter — see car rental insurance explained.
• Get the toll arrangement written onto the agreement, including how the charges and any handling element reach you.
• Photograph the car from every angle before driving away and again on return, including wheels, roof and windscreen.
• 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 arrive after the rental has ended, which is where most disputes begin — avoid hidden car rental fees covers the pattern.

Getting the best rate

Rates at Lisbon, Porto and Faro vary widely between suppliers for the same car on the same dates, and Faro in particular swings hard with the season. Compare car hire in Portugal on DiscoverCars, read the reviews for the specific pick-up location rather than the brand, and hold a full-to-full, free-cancellation rate you can re-shop as the dates approach.
