The deserted islands to the northeast of Alonissos are a paradise full of wild life. The island of Gioura has a unique species of wild goat. On Skantzoura and her steep cliffs the falcon finds refuge along with the rare Aegean seagull, while isolated reptile populations of great interest also live on these deserted islands. The island Piperi is the natural refuge of the monk seal. Approaching the island or visiting it is prohibited.
