Spiaggia di Marina di Capitana, Mediterranean beach in Quartu Sant'Elena, Italy.

Marina di Capitana is a Mediterranean beach on Sardinia's southern coast featuring white sand and clear blue water. The shoreline curves gently and is framed by a marina on one side and natural rocky features that create the sheltered bay.

The source documents only record Marina di Capitana as a beach in the Province of Cagliari, Sardinia, about 400 km southwest of Rome, with a mild climate averaging 17 °C and roughly 706 mm of rain a year. They give no founding date, fishing village or development history, so no such account can be stated.

The name Capitana comes from the Sardinian word for the tuna-fishing traps once worked from this stretch of coast. Today the small marina beside the beach still holds fishing and pleasure boats, and the shoreline takes its name from that maritime past rather than from any surviving fleet.

The beach provides changing facilities, umbrella rentals, and lifeguard supervision throughout the swimming season. Parking is readily available near the shore, and several restaurants are within easy walking distance for meals or refreshments.

The beach lies in the Quartu Sant'Elena municipality, about 400 km southwest of Rome by air, in the Gulf of Cagliari. The area has a mild climate averaging 17 °C, with July highs near 28 °C and February lows around 9 °C, and roughly 706 mm of rain a year, mostly between November and June.
