Dubbed the Summer Sensation, H2O is one of the newest stars of Belgrade's club scene and should be included on any serious clubber's Serbian itinerary. As the name suggests it's technically one of the city's fleet of party boats, or splavovi, anchored along the shores of the Danube and Sava rivers, but the interior bears little resemblance to its often ramshackle kin - other than the water out the windows. Currently attracts some of the biggest names of any of Belgrade's clubs, from Turbofolk and pop to mainstream international DJs like David Morales.
