The beautiful Cala Corsara is made up of four beaches. It is one of the busiest given the presence of the pier that allows landings. In the central beach there is a hollow rock similar to a cave called the Tafone di Spargi, famous because finds have been made inside it which date back to the Neolithic period and which are currently on display at the Sanna museum in Sassari. In prehistoric times the site represented an important crossing point for those men who wanted to reach Corsica on foot from Sardinia: a route that was viable at the time since the two islands were connected by a mountain chain while the sea level was lower by as much as 20 metres above the current level.
