Ada Ciganlija, 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 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. Owing to this popularity, Ada Ciganlija has been commonly nicknamed "More Beograda" (Belgrade's Sea), which was officially accepted as an advertising slogan in 2008, stylised as More BeogrADA. Apart from the sport facilities, a 7 kilometer-long beach of Lake Sava has a closely supervised, fenced-off children's swimming area. Ada Ciganlija features a tall sports observation tower and bleachers on multiple levels which is its most prominent structure as well and one of very few permanent solid structures. One of those structures is the "Jezero" hotel at the entrance. The northern edge of the island is lined with attached floating barges, or houses on the water owned by many inhabitants of Belgrade as a weekend refuge given the peninsula's exceptionally quiet and green environment. In addition, many city dwellers come to enjoy fishing excursions, picnics and barbecues. From the beach, stunning views of central Belgrade can be seen, and sunsets are particularly beautiful when viewed from here. Ada Ciganlija has in the past been a host to a number of local and international water sporting events such as competitions in rowing and kayaking. Belgrade has a reputation for offering a vibrant nightlife, and many clubs that are open until dawn can be found throughout the city. The most recognizable nightlife features of Belgrade are the barges (splavovi) spread along the banks of the Sava and Danube Rivers. The island has over 70 restaurants, bars and cafés as well as a café-cinema.
