Triangular crevice in the rock, reachable only by swimming or by canoe, on the southern coast of the promontory just after the Torre Paola Cave, towards the San Felice Circeo marina. Its name directly recalls the legendary tradition of the sorceress Circe, protagonist of the tenth book of Homer’s Odyssey, who according to myth lived on this very promontory, then thought to be an island, the Aeaea described by the Greek poet.
As you approach this splendid natural cavity, you notice large limestone blocks to the right of the entrance: they fell from above and are the ancient floor of a cave higher up. Once inside, climbing a few metres and looking up towards the top of the cavern, you see a very evocative sight: the entrance of the ancient upper cave framed by dwarf palms (Chamaerops humilis). Remember, though, that it is extremely dangerous: enjoy the natural spectacle without attempting the climb. A popular belief holds that this was the cave where the sorceress Circe came to bathe, away from prying eyes. It is said that it was connected directly to her palace, on the highest peak of the promontory, by a tunnel in the rock, a sort of secret staircase she could use whenever she wished to bathe in the waters of the gulf.
