  Sifnos, Syros, Tinos, Folegandros, as well as the "Minor Cyclades" comprising Donousa, Irakleia, Koufonisia and Schinoussa.

The Ionian Sea is home to one sole island group:

• The Ionian Islands: Zakynthos, Ithaca, Corfu, Cephallonia, Lefkada, Paxi, Antipaxi, Ereikoussa, Mathraki, Meganissi, Othoni, Strofades.

These islands, together with Kythira, which is however cut-off from the rest, opposite the southern Peloponnese (Lakonia), as well as neighbouring Antikythira, they constitute the Eptanissa. The islands of Gavdos (situated south of Crete), Elafonissos (in the Gulf of Laconia) and Trizonis (in the Gulf of Corinth), although not forming part of any group, are of unparalleled natural beauty.
