The Sirens' Island is an island in the Sea of Monsters, where the Sirens dwell. The beach has black volcanic rock and sand with a large cove that is filled with spikes, mines, broken wood, and shredded ships from past sailors that were lured to their doom. In Greek mythology, the Sirens sing so sweetly that they enchant sailors and lure them to their deaths. The island changes appearance, though, depending on what your heart desires. In older times, it was known as "Sirenum Scopuli", meaning "Rock of the Sirens" in Latin.
