Poros (from Greek Πόρος) is an island in the Saronic Gulf, separated from the northeastern coast of the Argolid (Peloponnese) by a channel only 200 meters wide: its name means “channel or passage.” It is reachable only by sea and is 32 nautical miles from Piraeus.
It has an area of 49 km² and about 4000 inhabitants.
The island is characterized by low hills, with the highest reaching 326 meters (Mount Vigla), and is covered with pines, lemons, figs, and olives. In fact, Poros is composed of two islands: Kalavria (the main one) and the islet Spheria, where the port is located. Over the centuries, the two islands have joined with an isthmus of land. Its inhabitants primarily engage in fishing, lemon cultivation, and tourism.
The capital is Poros, where the main port of the island is also located.
Poros was the island of Poseidon (Neptune), the God of the sea. Nowadays, it is mostly frequented by Athenians on weekends and is a very lively island, also due to the presence of a naval school.
The road network of the island consists mainly of a single road that connects the main towns and beaches. There is a local bus service, taxis, and car and scooter rentals available.
