Poros (Greek: Πόρος), older form -o and -on, is a picturesque small town located in the municipality of Elios-Pronnoi, some 40 km SE of Argostoli, 28 km SE of Sami and 12 km NE of Skala, in the southeast of Kefalonia, one of the Ionian Islands of Greece. Poros is effectively divided into three parts. Poros port, with its couple of tavernas and bars, connects the island with Kyllini on the Peloponnese area of mainland Greece via regular year-round ferry service. During the summer months a ferry may connect Poros with Zakynthos and a couple of tourist caiques offer cruises to Ithaca and the Blue Caves of Zakynthos. The harbour is also home to the local fishing boats which supply the area with fresh fish.
