Ada Ciganlija (Serbian Cyrillic: Ада Циганлија, pronounced [ˈǎːda tsiˈɡǎnlija]), colloquially shortened to Ada, is a river island that has artificially been turned into a peninsula, located in the Sava River's course through central Belgrade, the capital of Serbia. The name can also refer to the adjoining artificial Lake Sava and its beach. To take advantage of its central location, over the past few decades, it was turned into an immensely popular recreational zone, most notable for its beaches and sports facilities, which, during summer seasons, can have over 100,000 visitors daily and up to 300,000 visitors over the weekend.
