Overlooking the Sulcis archipelago, which includes islands such as San Pietro and Sant'Antioco, Portoscuso is one of the most interesting tourist destinations in southern Sardinia. Founded by the Spanish as a fishing village at the end of the 16th century, with the name of Puerto Escuso or "hidden port", this town later became an important trading hub - and that meant it needed a castle.
The imposing 16th-century tower still dominates part of the skyline, adding to the character of this little town. But Portoscuso is best known for its tuna fishing, a trade that has its own local festival. You can also see the Su Pranu Tonnara, a 17th-century structure used to kill the tuna after the catch. Even today, the tuna trap is still used each year between May and June.
The broad beaches and crystal-clear waters are just perfect for a spot of peaceful sunbathing. Although the beaches are crowded during the summer season, they are quiet and secluded during the rest of the year.
