For most trips to Cagliari, renting a car isn’t essential. Here’s what you can easily do without one, where public transport works well, and when having a car really makes a difference.
If you’re planning a few days in Cagliari, one question will probably come up sooner or later is this: do you really need to rent a car? The short answer is no, at least if your plan is mainly to explore Cagliari, go to the beach, eat out and have a fairly relaxed holiday. In some situations, a car can actually become more of a hassle than a help, especially if you’re staying in the centre and would only use it once or twice.
Things change quite a bit if Cagliari is just your base and you’re planning to spend most days somewhere else in Sardinia, perhaps exploring the southern coast around Chia, Villasimius or Costa Rei, or beaches that aren’t particularly well served by public transport. In that case, a car can be very useful and may even make financial sense if you’re sharing the cost with someone else — despite fuel prices being far from cheap as I write this.
So, going back to the original question — “Cagliari with or without a car?” — the most accurate answer is: it mostly depends on the kind of trip you have in mind.
For a first trip to Cagliari, you probably won’t need a car
Most of the places you’re likely to visit on a first trip to Cagliari are concentrated in a relatively small area, often not far from the port and railway station. Marina, Stampace, Castello and Villanova are all close to each other, and much of the city is easy to explore on foot. Cagliari isn’t a huge city either.
There wouldn’t be much point in driving between Piazza Yenne, Bastione di Saint Remy, the Cathedral and the streets of the historic centre. In some cases, finding somewhere to park would probably be more complicated than simply walking there. You could also end up entering or approaching a ZTL, the Italian name for a restricted traffic zone.
The area around Piazza Matteotti, Via Roma and the port is particularly convenient if you’re travelling without a car. This is where you’ll find Cagliari railway station, the ARST bus station and several urban bus stops. Marina and Stampace basically begin once you cross the road.
Castello is close too, although this is where you’ll start noticing Cagliari’s hills. The district sits above the lower part of the city, so expect some uphill walking through the historic centre on the way there.
Of course, a car-free trip is much easier if you stay in the centre or somewhere with good public transport connections. Choose an apartment well outside the central areas and you may end up relying on buses much more than you expected.
What can you actually do without a car?
Rather than simply saying that Cagliari is walkable, I think it makes more sense to look at where some of the places you’ll probably want to see actually are.
If you use Piazza Matteotti and the railway station as your reference point, for example, Bastione di Saint Remy is roughly a 10–15 minute walk away. From there you can carry on towards Castello and the Cathedral of Santa Maria. There’s some uphill walking involved, but you certainly don’t need a car.
The National Archaeological Museum, where you can see some of the famous Giants of Mont’e Prama, can also be reached on foot through Castello. If you don’t fancy walking uphill, you can take CTM bus 8 from Piazza Matteotti. The ride to the Buoncammino area takes around 8 minutes, followed by a short walk. Buoncammino itself is also a great place for a walk, with wide views over the city and towards the sea.
Another interesting stop is the San Benedetto Market. There is one important thing to know here: the historic market building has been closed for renovation since 2025, and the traders have temporarily moved to a new structure in Piazza Nazzari, not far from the original site. The market is still there, but for the time being the experience is different from what you might see in older photos and reviews online. The temporary market is still easy to reach from the centre without a car.
Outside the centre, the two most obvious examples are Poetto and Molentargius Park.
Poetto is around 6 km from central Cagliari, but it’s well connected by CTM buses, with extra services to the beach during the summer. A standard urban ticket currently costs €1.30 and is valid for 90 minutes, while a 24-hour ticket costs €3.30. If you’re coming in summer, though, don’t be surprised if some buses are very busy, especially at certain times of day.
I’ve written a separate guide to beaches near Cagliari you can reach by bus, including routes, ticket prices and what the different beaches are actually like.
Molentargius, best known for its flamingos, can also be reached by public transport. CTM services including the PF and PQ lines run towards the Poetto and Molentargius area. Exactly how much walking you’ll need to do depends on which entrance and part of the park you want to reach, but again, this isn’t somewhere you need to rent a car just to visit.
You’ve probably got the idea by now. If you come to Cagliari to explore the historic centre, visit the Archaeological Museum and stop at the market, you can already do all of that without a car. The same applies to many boat trips and organised tours, which leave directly from the port or from areas around the station.
If you want to add a day at Poetto or go and see the flamingos at Molentargius, a simple bus can still be enough — with all the usual pros and cons that come with using public transport.
Getting to and from the airport is easy too — most of the time
Elmas Aeroporto railway station is connected to the airport terminal by a short covered walkway, and trains reach Cagliari’s central station in less than 10 minutes. The ticket currently costs €1.30.
There are frequent trains for most of the day, so for the majority of flights this is probably the easiest way to travel between the airport and the city.
Things become more complicated at the edges of the timetable. Under the current regular schedule, the first train from central Cagliari to the airport leaves at around 5:10 am, while the last train from the airport into Cagliari leaves at around 11:07 pm. ARST also operates a late-night bus connection around midnight.
Timetables can change, and extra late services are sometimes added during the summer, so I’d always check Trenitalia and ARST for your exact travel date rather than relying on an old timetable.
If you need to be at the airport at 4:30 or 5 in the morning, public transport may simply not be practical. That’s when a taxi or a pre-booked private transfer starts to make much more sense.
Where having a car starts to make a real difference
If your plans are mostly Cagliari and the immediate surroundings — museums, archaeological sites, restaurants, evening walks, a boat tour and perhaps an organised day trip — I don’t see much reason to pay for a rental car for an entire week.
If, on the other hand, you already have a list of places outside the city, want to visit different beaches every day or plan to explore inland areas as well, the situation changes.
Villasimius, for example, is reachable by bus. But getting to Villasimius and getting to the particular beach you want to visit are not necessarily the same thing. You still need to work out the last part of the journey and plan your day around the available return buses.
With a car, you can leave when you want, change your plans, stop somewhere along the way or switch beaches if the one you chose turns out to be too windy or too crowded.
I don’t think there’s one answer that works for everyone here. It comes down to how much you’re willing to plan around public transport, how important flexibility is to you and, obviously, how much time you have.
The real limitation of public transport is flexibility
Within Cagliari, public transport is mainly operated by CTM. For many destinations outside the city, you’ll instead use ARST, the regional bus network connecting towns and villages across Sardinia.
For urban buses, the CTM BusFinder app is particularly useful: you can check services and buy tickets directly from your phone. Google Maps is also handy for checking routes and seeing when the next bus should arrive.
Outside Cagliari, you’ll usually need to plan a little more carefully.
Several places in southern Sardinia can be reached without a car using regional public transport, including Villasimius, Pula and some beaches around Chia. The problem is that reachable doesn’t necessarily mean convenient — or quick.
A journey that takes less than an hour by car can take considerably longer by bus and may also involve some walking. More importantly, you need to keep an eye on the return timetable.
I’m not saying public transport outside Cagliari is unusable or necessarily unreliable. Some connections work perfectly well. The real limitation is flexibility: if you want to stay an extra hour, change beaches at the last minute or decide to have dinner before heading back to Cagliari, you’ll still have to work around the last bus.
And missing the last bus from somewhere well outside the city can quickly turn a cheap day trip into a much more expensive taxi ride.
Taxi and Uber: there’s one important difference
If you normally use Uber at home, be aware that the service you’ll find in Cagliari may not be what you’re used to. Uber is available here, but Uber Taxi connects you with licensed local taxi drivers. So you shouldn’t arrive expecting a huge pool of cheap private UberX drivers.
For late-night journeys or very early airport departures, you can also pre-book an NCC — the Italian term for a private hire car with driver — or an airport transfer. Looking at published prices from several operators in 2026, transfers between central Cagliari and the airport generally start at around €25–30 per vehicle, but can rise to €40–50 or more depending on the time, vehicle and service.
A normal daytime taxi can cost less. The main advantage of a private transfer is predictability: you know in advance that someone should be there to pick you up at a specific time.
You don’t have to choose between “a car for the whole trip” and “no car at all”
There’s a third option that I think makes more sense for quite a few trips to Cagliari: rent a car for only part of your stay.
If you’re spending five days in the city, for example, you could easily walk and use buses for three or four of them, then rent a car for one or two days to visit Chia, Villasimius or somewhere else that’s awkward to reach by public transport.
That way you avoid paying for five or six days of rental, fuel and parking when the car might spend almost half your stay sitting unused.
Cagliari also has car-sharing services such as Playcar, which can be another option if you only need a vehicle for a shorter period. Before relying on it, I’d check the current registration requirements and whether your driving licence is accepted directly on the official website or app.
So before deciding, I’d ask yourself a slightly different question: how many of the things you actually want to do on this trip really require a car?
Would you be happy organising your days around buses and regional public transport, or would you rather pay more for the freedom of having your own car?
If you’re trying to work out whether a particular place is realistic without a car, leave a comment. If I know the route or can point you in the right direction, I’ll be happy to help.
