Renting a Car in Portugal: Everything I Learned From My Road Trip

Renting a car in Portugal? Here’s what I learned on my Porto-to-Algarve road trip, including tolls, fuel, parking and driving tips.

Planning a Portugal road trip? Rent the car. Just don’t rent it for the entire trip.

On our three-week trip through Portugal, my husband and I spent our first few days wandering Porto on foot, then picked up a rental car at Porto Airport and drove south through Coimbra, Óbidos, Ericeira, Lisbon, Évora and the Algarve before returning it at Lisbon Airport.

Honestly, Portugal was one of the easiest places I’ve road-tripped. The roads were excellent, driving between destinations was straightforward and having a car meant we could turn otherwise boring transfer days into stops at places like Costa Nova, Batalha, Nazaré and Peniche.

But there are a few things I’d do very deliberately again, and a couple of suggestions on what I’d change for next time.

Do You Actually Need a Rental Car in Portugal?

It completely depends on your trip.

If you’re visiting Porto and Lisbon only, save your money and take the train. I’ve spent plenty of time exploring Lisbon without a car, and honestly, you don’t need one. Both cities are much more enjoyable without worrying about a car.

But for our Porto-to-Algarve route, having one gave us the freedom to:

• ✔ Stop at Aveiro + Costa Nova on the way to Coimbra
• ✔ Visit Batalha + Nazaré en route to Óbidos
• ✔ Detour through Peniche before reaching Ericeira on Portugal’s Silver Coast
• ✔ Travel inland through Évora
• ✔ Explore Carvoeiro, Benagil, Lagos & Sagres at our own pace

Spend your city days car-free, then rent a car once the actual road trip begins. I’d make exactly the same choice again.

Where I Rented My Car & What I’d Do Again

We picked up our car at Porto Airport after three nights in the city and returned it one-way at Lisbon Airport.

For our route, this setup was ideal:

• Porto: no car
• Porto Airport: pick up when leaving the city
• Road trip: keep the car for the smaller towns, coast + Algarve
• Lisbon Airport: one-way drop-off rather than driving all the way back north

I’d definitely compare one-way rentals rather than automatically returning the car to the same location. Even if the rate is slightly higher, backtracking several hours just to save on a rental fee makes very little sense to me.

Search airport-to-airport first. It gave us an easy exit from Porto and an equally easy finish in Lisbon without navigating either city centre with luggage and a rental car.

If you’re still figuring out where to base yourself, I’ve broken down my favourite Porto neighbourhoods separately.

What You Need to Rent a Car in Portugal

The paperwork is pretty standard. For most rentals, you’ll need a valid driving licence, passport or ID, and usually a credit card in the main driver’s name.

Portugal’s tourism board says rental companies generally require drivers to be at least 21–25 years old, depending on the company, and to have held their licence for more than one year.

Before booking, I’d check the individual rental company’s rules for:

• Minimum driver age and any young-driver fee
• How long you must have held your licence
• Deposit amount
• Whether they require a physical credit card
• Whether your licence requires an International Driving Permit

The important bit is to read the rental conditions before paying, particularly the deposit and card requirements. Those are the details far more likely to cause an annoying airport-counter surprise.

Tip: I also screenshot the rental company address and return instructions before leaving Wi-Fi. It takes two minutes and saves a surprising amount of faffing around later.

Manual or Automatic? What I’d Choose in Portugal

If you’re comfortable driving a manual, great, you’ll usually have more choice.

If you need an automatic, I’d filter for automatic cars early rather than hoping one is available at the desk. This is especially important if you’re travelling in peak season or want a smaller car.

Personally, I’d choose the transmission you’re actually comfortable with rather than saving a little money and spending three weeks mildly stressed every time you hit a hill, roundabout or tight parking space.

And on a Portugal road trip, there will be plenty of all three.

Rental Car Insurance in Portugal: What I’d Check Before Booking

This is the part of car rental bookings that always seems designed to make you second-guess yourself.

At minimum, check exactly what the base rate includes and, more importantly, what the excess is if the car is damaged or stolen. Don’t assume “insurance included” means you have zero financial responsibility.

If you book through Discover Cars, their optional Full Coverage works on a reimbursement basis. You still leave the rental company’s security deposit, and if something happens, you pay the supplier first and then claim eligible costs back through Discover Cars.

For me, the biggest thing is knowing what you’ve actually bought before you reach the desk. I hate making insurance decisions while tired, holding luggage and being presented with three extra options I’ve never heard of.

Before pickup, I’d know two numbers: your security deposit and your excess. That alone makes the rental counter much less stressful.

Portugal Tolls: The One Thing to Sort Out Before You Drive

Portugal has both normal toll booths and electronic-only toll roads, which sounds more confusing than it needs to be.

With a rental car, my advice is simple: sort this out at the rental desk before you drive away. Many Portuguese rental cars have an electronic toll device installed (ours did!), with your toll charges passed on by the rental company.

Ask: “Is the toll transponder activated, and how will I be charged?”

Then check whether there’s a daily/device administration fee on top of the actual tolls.

I wouldn’t try to save a few euros by making the toll system more complicated. We covered a lot of Portugal by motorway, and this is one of those things I’d rather have automatically dealt with while I get on with the road trip.

What Driving in Portugal Is Really Like

I found driving in Portugal surprisingly easy.

The main roads were smooth, wide and well-marked, and motorway driving was much less stressful than I’d built it up to be in my head. Outside the historic centres, I rarely felt like I was battling the road.

The only places I’d actively avoid driving around for fun are central Porto and Lisbon. Narrow streets, hills, pedestrians, and parking headaches. None of it adds anything to your trip. I remember gripping the door handle on a couple of city streets in central Lisbon. I definitely wouldn’t wish that on anyone (nervously laughs).

Once you’re between cities, though, Portugal is a very forgiving road-trip destination. I’d happily drive the same route again.

Parking in Portugal: Where It Gets Annoying

Parking was rarely a problem on our road trip until we got into the bigger cities and historic centres.

In smaller towns and along the coast, we usually found somewhere without much drama, except for maybe the historic centre of Ericeira. Porto and Lisbon were the opposite story, which is another reason I wouldn’t keep a rental car there unless you genuinely need it.

My rule became pretty simple: if our hotel offered parking, great. If not, I’d rather park slightly outside the centre and walk than squeeze the car down a medieval lane hoping Google Maps knew what it was doing.

Also, always check the parking situation before booking accommodation. A hotel that looks perfectly located can become significantly less charming when you’re circling the block for the fourth time with suitcases in the boot.

Fueling Up in Portugal: A Couple Things Worth Knowing

We never had trouble finding fuel, but the drive from Évora toward the Algarve is noticeably sparser than most of this route. Before leaving Évora, we searched Google Maps for stations along the way, picked one that made sense and carried on. Worked a charm.

Once we reached the coast, the distances between the towns we stayed in the Algarve were easy with a car.

A couple things worth knowing at Portuguese petrol stations:

• Gasolina = petrol. Gasóleo = diesel. It sounds obvious written down, but “gasóleo” is exactly the kind of word I’d second-guess while standing at a pump with a rental car. Petrol is generally labelled 95 or 98.
• Many stations are self-service. If you pay at an automated pump, your card may temporarily show a larger pre-authorisation amount before adjusting to what you actually spent. With foreign cards, that hold can occasionally take a couple of business days to disappear.

My biggest tip is simply to photograph the fuel type when you pick up the car. Rental-car fuel caps or paperwork usually tell you exactly what it takes, and that saves the little moment of panic later when you’re staring at gasolina and gasóleo wondering which one you were told.

5 Rental Car Mistakes I’d Avoid in Portugal

There wasn’t much about driving in Portugal that felt difficult, but there are a few decisions that can make the whole experience unnecessarily annoying.

• Picking up your car too early. If you’re starting in Porto or Lisbon, enjoy the city first. Paying for a rental car just to park it for three days makes no sense.
• Ignoring the toll setup. Confirm how your rental company handles electronic tolls before leaving the desk. This is not something I’d want to figure out halfway down the motorway.
• Booking a huge car. Portuguese motorways are spacious, but historic towns are not. I’d choose the smallest car that comfortably fits you and your luggage.
• Assuming every hotel has easy parking. Check before booking, especially in places like Coimbra, Óbidos and Lisbon.
• Waiting until the tank is nearly empty. Most of the route is easy, but stretches like Évora to the Algarve have fewer obvious fuel stops. A quick Google Maps check beforehand solves the problem.

None of these are trip-ruining mistakes. They’re just the little things that separate a relaxed road trip from spending your afternoon arguing with Google Maps in a medieval alley.

So, Would I Rent a Car in Portugal Again?

Yep. In a heartbeat.

Portugal made road-tripping almost suspiciously easy once we were out of the cities. Good roads, manageable driving distances and the freedom to pull off for a beach, monastery or pastel-striped fishing village whenever we felt like it. Honestly, I am so glad we decided to spend our 3 weeks in Portugal this way.

My only strong opinion: don’t drag a rental car around Porto or Lisbon unless you have a very good reason. Pick it up when you’re ready to leave, sort out the toll situation at the desk, and go.

That’s really it. No dramatic warnings required.
