I Pagliai
Around the island you can find dozens of stones, more or less large, that all together resemble a host of monoliths. These stones are pyramidal in shape and their appearance recalls, in a very particular way, the haystacks that are stacked in the Italian countryside. One of them has a puncture in which it is possible to navigate in it for about twenty meters.
