Cagliari is the capital of Sardinia, rising above the southern coast of the island with views across the Gulf of Angels. Its historic districts climb the hills behind the waterfront, with the medieval Castello quarter offering narrow lanes, old stone buildings, and viewpoints overlooking the city and sea. The Bastione di Saint Remy is one of the most recognizable spots, especially around sunset.

The coastline is a major part of life in Cagliari. Poetto Beach stretches for several kilometers east of the city and is lined with beach bars and restaurants, making it a popular place for swimming, cycling, and long walks. In the city, visitors can explore the Roman amphitheater, browse the stalls of San Benedetto Market, or enjoy Sardinian specialties such as fregola, culurgiones, fresh seafood, and local cheeses. The nearby Molentargius-Saline Regional Park is home to large colonies of flamingos, while the wider southern coast offers secluded coves, archaeological sites, and scenic roads.
