Although the Piraeus port is the main transportation hub for the Aegean islands, there are different ports to go to the Ionian islands. For example, ferries from Killini port in Peloponnese serve ferries to Kefalonia, Zakynthos, and Ithaca, while ferries to Corfu and Paxi operate from Igoumenitsa port in Epirus. Visitors can book online ferry tickets to almost all Greek islands.
