The river begins in the Agrafa mountains in the western part of Karditsa regional unit. Since the late-1950s it flows into Lake Plastiras, a reservoir that supplies electricity and water to Thessaly and Central Greece, near Pezoula. Passing into Evrytania, it flows through a deep, forested valley with a few little villages and stone bridges. Since 1967, it empties into the Kremasta Reservoir, which is drained by the Acheloos. It forms the border between Evrytania and Aetolia-Acarnania. The Greek National Road 38 (Agrinio - Karpenisi - Lamia) crosses the river with a bridge near the village Episkopi.
