Sa Rocca is an area in the Northern part from the peninsula Sinis. It is worth going there as the area around and the whole peninsula is full of dazzling beaches and nature.
In the area you can find remains of the "Nuraghi", for example Thassos, one of the most famous cities in the phonic time. Here nature is still nature and very different.
Since there is no real center, the shops, restaurants, etc. are located along the road. The nearest towns are Cabras and Oristano, where there is a good range of shops, cafes and restaurants.
