The best things to do in Cagliari divide into three groups that have almost nothing to do with each other: a medieval upper town on a limestone ridge, an eight kilometre beach with a flamingo colony behind it, and one of the most important archaeological museums in the Mediterranean. You can do all three in two days, and most people do none of them because they land at the airport and drive north.
This is the list in the order I would actually work through it, with what each one costs and when to go.
What to book before you come
Cagliari is a cheap city to be a tourist in. The terrace costs three euros, the cathedral is free, the flamingos are free, and the beach is a bus ride. There are four things worth paying for, and three of them involve getting off the land.
- The Devil’s Saddle from the water. You can walk up the headland, and you should. But the limestone cliffs on its seaward side are only visible from a boat, and three hours out with a Sardinian skipper is how you see the shape of the gulf you have been looking down on. 4.9 across eighteen hundred reviews.
- Underground Cagliari. The best thing on this list and the least obvious. The city is hollow: Roman cisterns, quarried caves, wartime shelters cut into the rock under the streets you have been walking. Two hours, and it reframes everything above it.
- A swimming afternoon, four stops and a prosecco. The coves east of the city are hard to reach without a car and easy to reach by boat. Three hours, snorkelling included, and it solves the transport problem that otherwise decides your day.
- Eating your way through the old town. Fregola, bottarga, culurgiones and seadas are not obvious from a menu if you have never met them. Three hours with someone who orders properly is the fastest way into Sardinian food, which is not Italian food.
Everything else below is either free or costs about the price of a coffee.
The terrace above the square
The great pale terrace above Piazza Costituzione is where everyone starts, and it earns it. It is much newer than it looks, built in classical style between 1896 and 1902 by Giuseppe Costa and Fulgenzio Setti, and it functions as a grand staircase and viewing gallery joining the lower town to the walled quarter above.
Open daily, roughly 10:00 to 17:00 in winter and with a long afternoon break in summer, about 3 euros, with reductions for students under 26 and over 65s and free entry under 6.
Go in the morning for the light across the gulf, or at dusk for the city coming on underneath you.
The medieval tower you can climb
On Via Santa Croce there is a square white limestone tower built in 1307, part of the Pisan defences, with one side left completely open so you can see the timber floors stacked inside it. It is named for a small carved elephant on its face, which is easy to miss.
Same hours as the terrace, about 3 euros, no booking needed. The stairs are steep and the top is the better of the two high views because it is smaller and less busy.
The amphitheatre cut into the hill
On the western flank of the hill there is a Roman amphitheatre that was not built so much as excavated: the tiers are carved down into the living rock rather than constructed in blocks, so what you are looking at is a hole in the hillside shaped like a theatre.
It is unusual and it is worth seeing. It has also been subject to restoration and access restrictions in recent years, so check locally on the day rather than building your morning around it.
The museum, and the bronzes
The Museo Archeologico Nazionale sits at the top of Castello in the old citadel, and it is the single most important thing in the city.
Three floors covering roughly seven thousand years. The Neolithic mother goddesses are extraordinary. But the reason to come is the bronzetti: small nuraghic bronze figures of archers, hunters, wrestlers, priests and shamans, with elongated bodies and enormous eyes, made by a civilisation that left no writing. They are the closest thing to a voice that culture has.
The museum also holds several of the Giants of Mont’e Prama, the oldest monumental sculptures in the Mediterranean, dated to the 8th and 9th centuries BC. Which giants are on display in Cagliari and which are at Cabras does move, so if they are your reason for coming, check before you travel.
Allow two hours if you like museums, one if you do not.
The market, and go early
The Mercato di San Benedetto is a working civic market, not a food hall for visitors. Fish downstairs on marble under strip lights, produce and cheese and bread upstairs. Mornings only, closed on Sunday.
Go for the fish floor even if you have no kitchen. It is where the bottarga comes from, where you understand what the restaurants are working with, and where nobody is performing for you.
Poetto, which is a proper beach
Cagliari has seven or eight kilometres of pale sand inside its bus network, running from the headland to Quartu Sant’Elena. The water stays shallow and clear for the first hundred metres.
PF and PQ buses from Piazza Matteotti, fifteen to twenty minutes, around 1.50 euros. Concessions charge roughly 5 to 12 euros for a sunbed and umbrella and the free public stretches at the western end are perfectly good.
The full version is in my guide to Poetto beach and the Devil’s Saddle.
The flamingos behind the beach
Behind Poetto lie over 1,600 hectares of former salt pans, now the Molentargius-Saline regional park, and they hold greater flamingos year round, with the peak on spring and autumn migration.
Free. Open dawn to dusk. Take the same beach bus and get off at Ospedale Marino, then walk about ten minutes to the gate. There are boardwalks and hides, and in the evening the birds feed close enough that a phone will do.
This is the thing I would put highest on a list of what makes Cagliari different from other Italian cities, and almost nobody comes for it.
The walk up the Devil’s Saddle
At the western end of the beach the land rises into a limestone headland. A steep path climbs from behind the Calamosca hotel to a viewpoint and the remains of an Aragonese tower, with the whole gulf laid out below.
Short but completely exposed, so early morning or late afternoon only. Proper shoes, water, and do not attempt it at midday in August.
An evening in Marina
Not a sight, but the most reliable pleasure in the city. After about eight the flat grid of streets between the upper town and the port fills with tables, the stone gives back the day’s heat, and the whole city seems to be outside.
Where to eat, and what to order, is in my guide to where to eat in Cagliari.
If you have a day spare
Get out to the archaeology. Nora is forty-five minutes southwest, a Roman city on a promontory with part of it under the sea. Su Nuraxi di Barumini is an hour inland, UNESCO listed, and guided entry only.
Frequently Asked Questions
What is Cagliari best known for?
Its walled upper town on a limestone ridge, the Poetto city beach, the flamingo colony on the salt pans behind it, and the national archaeological museum, which holds the finest collection of nuraghic bronzes on the island.
How much do Cagliari’s main sights cost?
Very little. The terrace above Piazza Costituzione and the medieval tower are around 3 euros each, the cathedral is free, and the flamingo park is free. The museum is the main paid attraction, and out of town Su Nuraxi di Barumini is 15 euros including its guided tour.
Can you see flamingos in Cagliari?
Yes, reliably and year round, in the Molentargius-Saline park behind Poetto beach. Numbers peak during spring and autumn migration. It is free, open from dawn to dusk, and reachable on the PF or PQ bus to Ospedale Marino plus a ten minute walk.
Is the Cagliari archaeological museum worth it?
Yes, and it is the one paid indoor attraction I would not skip. The nuraghic bronzetti are the best surviving record of a civilisation that left no writing, and the museum gives Barumini and Nora the context that makes them legible.
