The area of Kožara is around 1 square kilometre (0.39 sq mi).[3] The name means "leather island" in Serbian.
The island is floodable, completely covered with forest and without permanent population. On the Jojkićev Dunavac's mouth into the Danube, across Kožara, a weekend-settlement of Mika Alas is located. There are several permanent elongated bogs on the island.[1][2]
It represents an oasis of undisturbed natural life even though it is only 600 meters away from the old core of Belgrade (the neighborhood of Dorćol, right across the Danube). Despite this, in 2005 Belgrade City government announced that Kožara is the most likely site of the future much enlarged semi-artificial island envisioned as the twin-island of the Veliko Ratno Ostrvo, also on the Danube, but some 800 meters to the southwest. Unlike Veliko Ratno Ostrvo which is protected by the law and any human interference is prohibited, future Kožara (probably with changed name; temporary name for the time being is Čaplja) is projected as the island-aqua park and major tourist attraction. However, as of August 2022 no work has begun on this project.
