Wind and sea have sculpted Capo Testa's granite into rounded boulders, slabs and hollows that look like an open-air gallery. The peninsula, joined to the mainland by a narrow isthmus with a beach on each side, lies about four kilometers from Santa Teresa Gallura and looks across the Strait of Bonifacio to Corsica; on a clear day you can pick out the Lavezzi Islands.
The Romans quarried this stone from the first century BC, and the columns of the Pantheon were probably cut here; Pisan masons took columns for their cathedral in the twelfth century. The Valle della Luna, a maze of boulders running down to small coves, became a hippie haunt in the 1970s and remains the most beloved walk.
