About Ithaca

Ithaca lies off the west coast of Greece between Kefalonia and the mainland, a green Ionian island of cypress, olive terraces and deep bays. Vathy is the main harbour town and home to a small archaeological museum, while Kioni and Frikes keep a village feel and Gidaki and Filiatro are the best known swimming coves. Boats link it with Kefalonia and Patras, so the Melissani cave and Assos are easy add-ons. Late May to early October is the season, and winter is wet and quiet.
