About Cagliari

Cagliari climbs from a long urban beach to a fortified Castello quarter of towers, domes, and views over the Tyrrhenian. May to June and September to October deliver warm swimming at Poetto, manageable crowds, and pleasant evenings for seafood along Via Roma. July and August are hot and busy—reserve parking and expect packed lidos. Winter stays mild and sunny by Italian standards, good for archaeology at Nora or Tuvixeddu without beach plans. Rent a car for Costa Rei or the southwest coves on a longer stay.
