The lagoon extends north of the Bay of Vlorë on the eastern shore of the Strait of Otranto and is separated from the sea by a narrow littoral strip, consisting of an alluvial dune.

It has a surface area of 41.8 km2 (16.1 sq mi) with a maximal depth of 1.5 m (4.9 ft).

It is situated within the boundaries of the Vjosa Wild River National Park, and has been recognised as an important Bird and Plant Area of international importance.

[4] It is formed by the constant accumulation of solid flow of the Vjosa River, which originates within the Pindus Mountains close to the border between Albania and Greece.

A wooden footbridge connects mainland to the island, where a 13th-century monastery is located.
