The name Carloforte comes from the famous tuna fisheries. For decades the local fishermen lived thanks to tuna fishing. This activity, which was at the beginning only a momentary way to survive, became a real industry in which the whole population invested in for its future. However, the 70's registered the decrease of this revenue, once considered inexhaustible. The foreign shipping companies resorted to technology in order to catch the tuna in international waters. Captured far from the coasts, the fish didn't come back anymore, not even to lay eggs. And in the end, they disappeared. Nowadays, the tuna fisheries are only a memory, a sort of tribute to themselves, the symbol of a village not more than three hundred years old.
The cliffs' ruggedness, the solitary white, sand beaches and the characteristic vegetation represent an important visiting card for anybody in search of the "real" Sardinia. It's a natural life in close contact with the sea, a life of numerous difficulties and isolation. Carloforte's allure is definitely its authenticity. It is proudly defended by its population and also by its sea; a strong and untameable sea. The highest point of the island is Guardia dei Mori. From this hilltop called "bricco" and where there still is an old abandoned lighthouse, the view reaches out in all directions, beyond the wonderful pine woods surrounding the hill. San Pietro's vegetation is no longer as thick as it used to be; before the junipers were cut down in order to build the village.
