The Strait of Ithaca is a strait separating the islands of Kefalonia to the west and Ithaca to the east. The Strait is approximately 20 km long and 4 to 6 km wide. It runs from south to north, starting at Cape Dichalia and Cape Agios Andreas and ending at Cape Viotis and Cape Exogi. The boating route linking the ports of Sami and Fiskardo lies in this strait. The Strait connects to the Ionian Sea on both sides. The Agia Effimia and Sami bays lie to the southwest.
