An islet in the Sava River dubbed as ‘Belgrade’s Sea’, it is the most popular swimming venue and outing area in Belgrade. The tips of the islet are connected to the mainland with embankments, thus creating an artificial lake 4,2km long, with an average width of 200m, and the depth of 4-6m. Both sides of the lake feature fine pebble beaches, dotted with cafés, restaurants and numerous sports venues. There is also a designated picnic area. The swimming season (when beach lifeguard service operates from 10:00 to 19:00) is open from 15 June to end September. The water is warm and clean, but rather muddy, so you cannot see much when you dive. In addition to water sports (swimming, kayaking, rowing, windsurfing, water skiing, fishing) Ada Ciganlija offers a great number of free venues for football, basketball, handball - you need only bring a ball and a crowd, plus there is a trim trail, biking and roller-skating paths, facilities for table tennis, tennis, bowling, artificial rock climbing, a bungee jumping platform (55m high), a nine-hole golf course, mini golf, rugby, field hockey, paintball, aqua football facilities, artificial alpine skiing and snowboarding slopes, skateboarding ramps, adventure park, and more. There is also a Robinson Crusoe Island theatre and entertainment feature for children.
