The most famous beach in Cagliari is Poetto. It attracts the largest number of people, so if you want to secure a good spot, it's best to come early in the morning. However, Poetto offers the widest range of water activities, and there is also a water park nearby. The rental prices for beach equipment at Poetto are significantly higher.
You can combine a beach vacation with a short excursion by visiting Nora Beach, located 27 km from Cagliari. After enjoying swimming and relaxing on the white sandy beach, it's worth visiting the local caves and the archaeological excavations of the ancient Phoenician city with the same name.
Santa Margherita Beach, located 8 km from Nora Beach, is surrounded by a magnificent pine forest. Swimming in the sea while inhaling the scent of pine trees - isn't it a paradise for city dwellers?
