The Slunjčica (natives also call it Slušnica) is a river, which flows through the Kordun region in central Croatia. It partly flows underground through porous karst (limestone soil) and surfaces in the vicinity of the city of Slunj. At Rastoke the Slunjčica leads into the river Korana, which reaches this point after passing the Plitvice Lakes National Park. The city of Slunj bears its name from this river.
