Zrmanja starts its 69 kilometre long course in the southern part of Plješevica Mountain. On its way to Novigrad Sea where it flows, it passes through the narrow valleys and magnificent 200 metres deep canyon.
She is a typical karst river with many waterfalls and strong rapids which makes her ideal river for white water sports. Rafting fans named her Beauty and Beast, because at the time of high water level her flow makes one of the best rafting locations in this part of Europe. On the other hand, Zrmanja with its tributary Kupa, during the summer is quiet and peaceful, easily carrying the visitors through the fascinating landscape.
