Ozeros
Lake Ozeros is a lake located west of Agrinio. The lake is formed from the waters of the Acheloos river, flowing from the northwest. The lake has a surface of ca. 10 km and an average depth of 8–10 m, but this varies greatly with the season. The GR-5/ E55 ( Antirrio - Agrinio - Ioannina) runs to the northeastern side.
