The area was proclaimed national park in 1985. The National Park includes one or more preserved or insignificantly altered ecosystems. By the submergence of the riverbed, the Krka River is about 72.5 kilometers long and has its source at the foot of the Dinara mountain. With seven travertine waterfalls and a total fall of 224 meters, the Krka is a natural and karst phenomenon. The beauty of Skradinski buk, the longest travertine barrier on the Krka River and one of the most famous beauties of Croatia, is particularly remarkable
