This is one of the main attractions of San Pietro, in the territory of Carloforte. La Conca is found in the Mezzaluna gulf, in the southernmost tip of the island, and is characterised by plunging cliffs, a rocky seabed and clear, deep water. The rays of the sun create multi-coloured reflections thanks to the high, dark rocks. This is the ideal place to relax and have fun, especially if you love swimming.

The beach has a car park and is popular with underwater fishing, diving or snorkelling enthusiasts. An unforgettable panorama is also guaranteed for cavers, with several caves opening onto the cove. The surrounding landscape is completed by Mediterranean bushes, such as cistus, strawberry trees and myrtle.
