Looking for things to do in Cagliari? The capital of Sardinia is easy to explore on foot, from the hilltop citadel of Castello down to the harbour district of Marina. Visitors come for its viewpoints over the gulf, its archaeological museum and the giants of Mont’e Prama, then for Poetto beach and the flamingos of the Molentargius salt pans on the edge of the city. Allow 2 to 3 days, ideally in May-June or September-October.
This guide brings together the highlights, a three-day plan, the budget, the best areas to stay and the official climate, with a calculation other guides do not give: the number of rainy days to expect during a one-week stay, by month.

Things to do in Cagliari: the highlights
Castello and the Bastion of Saint Remy
Castello is the upper town, enclosed by Pisan and Aragonese walls. Climb up via the monumental stairways of the Bastion of Saint Remy, built at the turn of the 20th century: its terrace offers one of the finest views over the rooftops, the port and the gulf. In the lanes you pass the Royal Palace and the Archbishop’s Palace, and find the medieval Elephant and San Pancrazio towers, which are sometimes closed for works.
Santa Maria Cathedral
Castello’s cathedral, founded in the 13th century, was given a neo-Romanesque façade in the 20th century. The Baroque interior and the Crypt of the Martyrs, carved into the rock, are worth a visit. Modest dress required (shoulders and legs covered).
The National Archaeological Museum and the Citadel of Museums
At the northern entrance to Castello, the Citadel of Museums brings together several collections. The National Archaeological Museum traces the prehistory and Nuragic civilisation of Sardinia, with the stone statues of the giants of Mont’e Prama. The National Art Gallery is next door.
Marina, Stampace and Villanova
Below Castello, Marina is the district of restaurants and shops, lined by the arcades of Via Roma facing the port. Stampace, to the west, and Villanova, to the east, are more residential, with churches and lanes full of flowers. The covered San Benedetto market is the best place to discover Sardinian produce; come in the morning.
The Roman amphitheatre and the Tuvixeddu necropolis
The amphitheatre, partly carved out of the rock, recalls Roman Karales. Tuvixeddu hill holds a vast Punic necropolis, with tombs dug into the limestone.
Poetto, the Sella del Diavolo and the flamingos
Poetto, a long city beach, is reached by bus from the centre. At its western end, the Sella del Diavolo (“Devil’s Saddle”) can be walked for views over the gulf, starting from Calamosca cove. Behind the beach, the Molentargius-Saline nature park is home to flamingos that can be seen all year round.
Around Cagliari
The archaeological site of Nora, to the south-west, combines Phoenician and Roman remains by the sea. The Nuragic village of Su Nuraxi at Barumini, a UNESCO site, is reached by road to the north. To the east, Villasimius and the coast towards Costa Rei have beaches with clear water. A car is useful for these trips.
