Second: they always say Sardinians don't know how to fish, and they're not really sea people, as they were originally mountaineers. True, but this place you see here is fairly different. Golfo Aranci in fact is inhabited since less than a century, and it was founded by coral fishermen who came here from the island of Ponza, in "Continental Italy". Yes, you heard well, Sardinians call Italians "Continentals".
Last thing: no, Golfo Aranci is not Golfo degli Aranci, and no, there is no orange tree here. It seems the name "aranci" comes from a particular kind of seaweeds in the area. But don't get afraid, even seaweeds look great in Sardinia.
