The third largest island in the archipelago, it stands majestically surrounded by dense vegetation. It can only be reached by sea, but it is well worth the effort: granite rocks, dreamy beaches, peculiar sand dunes that characterise some coves and a hinterland rich in typical Mediterranean scrub vegetation.

For those arriving from the west, the island appears unwelcoming, with sheer cliffs and no beaches. But do not be deceived, just continue eastwards and the visitor will be inundated with some of the most beautiful beaches in the Archipelago: Cala Corsara, Cala Granara and Cala Ciaccaro.

When you arrive on the island, you will be struck by the shapes of the rocks, each more bizarre than the other. The most famous are those of the witch and the bulldog, but there are many others: it is up to you to find them and imagine what they are like.

A peculiarity of the island is the presence of small streams, called vadine, which are particularly abundant in the rainy season and offer the visitor an unusual scene. These are small rivers that flow down to the sea, breaking through the beaches to make their way. Spargi is not only nature and unspoilt/untouched beaches, but also military history. In fact, there are several fortifications on the island, built between the late 19th and early 20th centuries.

The island is also home to several rare species, in particular the Armeria pungens, which could be considered the symbol of the island. It is precious for the Archipelago of La Maddalena because, although it is widespread along the Gallurese coast, it is rare in the Park area. On the island of Spargi it can be found in Cala Ciaccaro and Cala Corsara, where it flowers in late spring.

The Phoenician juniper (Juniperus phoenica), the Tree heath (Erica arborea) and the Strawberry tree (Arbutus unendo) are some of the 400 species recorded on the island.

To the north-west are the islets of Spargiotto and Spargiottello, protected by the Park Authority as important nesting sites for marine avifauna such as the Audouin's Gull (Laurus audouinii), the Scopoli's shearwater (Calonectris diomedea), the Mediterranean shearwater (Puffinus yelkouan) and the European Storm Petrel (Hydrobates perlagicus).

An important archaeological discovery was made off the coast of Spargi, on the Corsara shoal (at a depth of -18 metres) by the Magdalenian diver Lazzarino Mazza in 1939. The cargo of a Roman honorary ship (110 B.C.) was brought to light, and later, in 1958, thanks to the director of the Centro Sperimentale d'Archeologia Sottomarina di Albenga, Nino Lamboglia, and the journalist Gianni Roghi, the research campaign began. A second campaign was conducted in 1963, which unfortunately revealed that many of the artefacts had been stolen by poachers. Everything that was found, around 2,000 amphorae and ceramics, is now kept in the ‘Nino Lamboglia’ Naval Museum on La Maddalena.

Beaches
Arriving from La Maddalena, the beach of Cala Corsara slowly opens up, leaving the visitor amazed until the very end. The colour of the crystalline water contrasts with the colours of the granite rocks, creating an unforgettable spectacle.

A point of interest on the beach is the tafone, the first 'house' on the island. The traces found (potsherds, bowls and a tripod base) tell of the life of distant peoples who sought refuge here. Travellers heading north would have stopped on the island during storms to wait for a safe passage through the Strait of Bonifacio. The use of the tafone lasted for a long time, from the ancient Neolithic period to the beginning of the Nuragic period, and was resumed in more recent times: shell casings and ammunition from weapons dating from the Second World War have been found.

Cala Granara, on the east coast of the island of Spargi, is a spectacular beach with exceptionally turquoise waters. The shallow, sandy seabed will amaze visitors. Behind it, winding sand dunes and dense vegetation protect the beach, enveloping tourists in fresh Mediterranean scents.
The beach is divided in two by a rocky headland, creating two coves.

Cala Soraya, or Cala Ciaccaro as it was originally called by the people of La Maddalena, is a paradise characterised by a flourishing Mediterranean scrubland with species such as the spiny thrift (Armeria pungens), the helichrysum and the lily. 

The cove was renamed Cala Soraya after the events of the former queen of Persia, Soraya Esfandiary, who, repudiated by her husband, was said to have been seen frequenting Cala Gavetta and someone thought it would be a good idea to give her name to this sandy mountain of Spargi.
