Even if it is quite small, the beach of Guidi offers a show of rare beauty for the light colour of its very fine sand which alternates with dark rocks and its crystal clear waters. The underwater world, which alternates among sandy areas and blooms of poseidonia, is variegated and multicoloured with a gently sloping sea shelf, offering the possibility to spot a number of different fish species. The beach is only a few kilometres from the town of Carloforte, founded at the beginning of the 18th century by Ligurian fishermen transferred from the island of Tabarka in Tunisia, and a short distance from the other beaches on the west coast too.
