Things to Do in Cagliari: Castello, Poetto, Flamingos and Food (2026)

The best things to do in Cagliari fit into two or three easy days. You get a walled hilltop quarter, a long city beach, a lagoon full of flamingos and a busy morning food market. In addition, Sardinia’s capital is compact, so you can mix all of them without a car. This guide puts them in order, with the practical details checked in September 2026.

Things to do in Cagliari at a glance

If you only have one day, however, a guided walk links the old town and the viewpoints fastest. Our page on a guided Cagliari tour compares two options side by side. As a result, you can pick one before you land.

Castello: the walled old town above the port

Castello is the historic hilltop quarter, and it is where most first-time visitors start. The Pisans fortified it in the 13th and 14th centuries. As a result, you still enter through massive gates. Then you walk under two white limestone towers, the Torre dell’Elefante and the Torre di San Pancrazio. Look for the small stone elephant on the first one.

Inside the walls, the lanes are narrow and quiet. For example, the Cathedral of Santa Maria faces a small square with the old Palazzo Regio beside it. Meanwhile, the edges of the quarter also open onto terraces with views over the port, the lagoon and the salt flats. Wear shoes with grip, since the stone paving gets slippery.

How to get up to Castello

The climb from the Marina district is short but steep. Instead of walking all the way, look for the public elevators that link the lower town with the old quarter. Then walk down at the end of the day. In short, go up by elevator and come down on foot.

Bastione di Saint Remy and the city views

The Bastione di Saint Remy is the grand stone terrace that links the lower town with Castello. It was built between the late 1800s and early 1900s on top of older Spanish walls. Today, the upper terrace, the Terrazza Umberto I, is a free public viewpoint. In fact, it is one of the simplest things to do in Cagliari at sunset, when locals gather with a drink.

Then, continue along the walls to the Bastione di Santa Croce in the old Jewish quarter. It faces west over the rooftops and the lagoon, so it catches the evening light even better. Together, the two terraces give you sweeping free views in under an hour.

Rainy-day things to do in Cagliari: the museums

The National Archaeological Museum sits in the Cittadella dei Musei, at the northern tip of Castello. Above all, go for the nuraghic bronze statuettes, small figures of warriors, priests and animals made by Sardinia’s Bronze Age culture. The museum also shows some of the stone giants of Mont’e Prama, which are unique in the western Mediterranean.

According to the museum’s official page (checked September 2026), it opens daily from 8:30 a.m. to 7:30 p.m., and the ticket office closes at 6:45 p.m. A full ticket costs about €10 (checked September 2026) and also covers the Pinacoteca Nazionale next door. Visitors under 18 enter free. Hours can change for special days, so check the page before you go. For the national picture, see our guide to free museum days in Italy.

The Pinacoteca is a short walk away in the same complex. By contrast with the bronzes, it focuses on Sardinian and Catalan altarpieces from the 15th and 16th centuries. It is also a quieter visit, so it suits a hot afternoon.

Outdoor things to do in Cagliari: Poetto and the Sella del Diavolo

Poetto is Cagliari’s city beach, a long strip of pale sand. It runs east from the Sella del Diavolo headland toward Quartu Sant’Elena. It has beach clubs, open public stretches and kiosks, and locals use it year-round. In fact, spending a slow afternoon here is among the most local things to do in Cagliari.

For a short hike, then, climb the Sella del Diavolo, the “Devil’s Saddle”, from the Marina Piccola end of the beach. The trail is exposed, so start early in summer and carry water. In return, you get views of the whole gulf. City buses also run from the center to Poetto. However, check current lines and tickets with the local operator, CTM, before you travel. For more coastal ideas, see our guide to Italian beaches.

Molentargius park: flamingos inside the city

Molentargius is a wetland park between the city and Poetto, made of lagoons and old salt pans. Its best-known residents are the pink flamingos. According to the park, Molentargius has in recent years been the most important flamingo nesting site in the Mediterranean. As a result, you can see them wading within sight of apartment blocks.

The green areas are free. The park’s official page (checked September 2026) lists them as open from 6:30 a.m. to 9:00 p.m. between March 1 and October 15. From October 16 to February 28, they open from 7:00 a.m. to 6:00 p.m. In addition, the flat paths suit walking and cycling, so rent a bike and loop the lagoon. Also bring binoculars, since the birds keep their distance.

Things to do in Cagliari for food lovers

Cagliari’s food mixes the sea with Sardinia’s shepherd traditions. For example, try fregola, a toasted semolina pasta often cooked with clams. Then look for culurgiones, hand-pleated pasta filled with potato, pecorino and mint. Also order bottarga, cured mullet roe, grated over spaghetti. Finally, finish with seadas, fried pastry filled with cheese and topped with honey.

The San Benedetto market, in its temporary home

San Benedetto is the city’s historic covered market, famous for its fish floor. However, the old building is closed for renovation. In March 2025, its traders moved to a temporary market in Piazza Nazzari, according to the City of Cagliari (checked September 2026). The hall stands on Via Santa Alenixedda, next to the Teatro Lirico. The city expected the move to last about two years. The temporary hall opens Monday to Friday from 7:00 a.m. to 2:00 p.m., and Saturday until 3:00 p.m. Go early for the best fish.

In the evening, the Marina district fills with trattorias and bars. For a pre-dinner drink, see our guide to aperitivo in Italy. If you prefer a guided tasting, browse our food tours in Italy.

Getting to and around Cagliari

Most visitors fly into Cagliari Elmas airport. Trains stop at the airport station about every 20 minutes, every day, from early morning to late evening. That is according to Trenitalia (checked September 2026). A covered walkway links the station to the terminal. The ride into Cagliari’s main station is short, and the station sits beside the port and the Marina district.

In the city, walk the historic center and use buses for Poetto and Molentargius. Meanwhile, a car only helps for day trips along the south coast. For rail tips across the country, see our guide to trains in Italy.

When to visit Cagliari

Cagliari has mild winters and hot, dry summers. As a result, most outdoor things to do in Cagliari feel easiest in late spring and fall, when the hilly old town is cooler. In addition, the sea usually stays warm enough to swim well into fall. By contrast, July and August bring heat and crowds on Poetto. For seasonal planning across the country, see our guide to Italy in fall.

Cagliari charges non-hotel lodging more from July to September; see our Italy tourist tax guide.

Cagliari is the natural start for the south of the island. See our Sardinia itinerary for 7, 10 and 14-day routes that begin or end here.

For day trips from the city, we compared two options for a Barumini tour to Su Nuraxi, and two for a Cagliari beach tour to Chia and Tuerredda or Villasimius and Solanas.
