Poros consists of two islands, the small volcanic islet of Sfairia over which Poros town houses cluster on its hillside and the pine-swathed Kalavria.
Poros lies 31 n. miles from the port of Pireaus and is one of the most popular islands for sailing and yachting. Poros bay will offer you many small and quiet spots for relaxing.
Poros takes its name from the sea passage that separates the island from the Peloponnesian mainland.
The first houses were built in 1463 at the top of the hill.
