Poros is a small Greek island in the Saronic Gulf, just 31 km². The traditional village of Poros is the capital and port of the island. The special feature of Poros is its close distance from the opposite shore of the Peloponnese mainland.

Poros is a lush island worth exploring. Apart from the town of Poros which is built on a small hill, important sights to visit are the ruins of the ancient temple of Poseidon, the Old Russian naval station and the historic Monastery of Zoodochos Pigi (The Monastery of the Life Giving Spring).
