Kálamos (Greek: Κάλαμος, known in antiquity as Καρνος – Karnos), is a mountainous island and a former community in the Ionian Islands, Greece. Since the 2011 local government reform it is part of the municipality Lefkada, of which it is a municipal unit. It lies east of Lefkada, near the Greek mainland. It has an wintering population of around 500 people, which is swelled substantially in the summer by tourists. The name Kalamos means reed in Greek and the presence of this plant along its coastline in the past may have given its name. Another version is that the island had several beaches with good sand (Kali Ammos in Greek) hence the name given. Its population was 496 at the 2011 census. The land area is 24.964 kmÂ² (9.639 sq mi), and its highest point is 754 m (2,474 ft) above sea level.
