There are 7 Ionian Islands: Kefalonia. Zante(Zakynthos), Lefkas (Lefkada), Ithaka (Ithaki), Corfu (Kerkyra), Paxos and Kythira.
Kefalonia is the largest of the Ionian islands with Zante (Zakynthos) to the south, Lefkas (Lefkada) in the north and its sister island, Ithaca (Ithaki) a few miles off its eastern coast. North of Kefalonia, near Lefkas, there are many smaller islands, such as Meganissi, Madouri, Skorpios, Skorpidi, Thilia, Tsokari, Sparti, Heloni.
Wherever you go on Kefalonia you should be able to see another island in the distance whether it is one of the tiny islets such as Dias near Avithos and Vardiani near Lassi in the south of the island or scenic vistas across the Ionian sea to the Ionian islands beyond. The larger islands are connected by ferry-boat and some by water-taxi. Others are only reached by cruiser, yacht or motor-boat.
