Acherontas and Kalamas

Located in Northern Greece, in the Epirus region, the outfalls of the rivers Acherontas and Kalamas into the Ionian Sea together with the marsh of Kalodikiou form the National Park of Kalama-Acherontas Rivers.

Brief description

It is an area with unique aesthetic and ecological value, as well as historical as according to Greek mythology, Acherontas was the river where Haros (Charon or “Death”) was transferring (by boat) the deceased to the gates of Hades (Adis - underworld).

The beautiful canyon that crosses the river Acheron with the steep slopes and dark green clear water is an area of exceptional biogeographical interest which contains remarkable habitats that host many rare or endangered species of fauna and flora. It is also an area with unique natural features, such as marshes, coves with dunes, magnificent coastal ecosystems with steep cliffs covered with pine forests, which provide to the area a distinct biological landscape and aesthetic value. The highly rugged landscape of the Acherontas Canyon, is tied to the ancient Greek mythology as the Oracle of the Dead or “Nekromanteio” lies just footsteps from the banks of the Acheron River. The whole area has been declared by UNESCO as World Cultural Heritage. 

The Kalama River Delta formed by the outfalls of the old and new river bed with its shallow lagoons and marshes is one of the most important wetlands of western Greece and Europe as due to its geographical position is an integral part of western migration route of birds.

The marsh of Kalodiki is also a wetland of ​​great ecological value and great aesthetics due to its importance for the birds’ western migratory route and its natural features (freshwater marsh, waterlilies etc.). At the time of flowering of the European White Waterlily (Nymphaea alba ) the view of the marsh is unique.
