Among the rivers in the Croatian karst Krka is for sure the most strange one. This river is known for its numerous waterfalls which, like those at Plitvice Lakes, were created through the sedimentation of a special form of limestone.
The park includes the larger part of the course of the River Krka, together with the neighbouring coastal area, from the historical town of Knin, near the river 's source, to Skradin, another historical town. Here after some magnificent waterfalls the river gradually wends its way into Lake Prukljansko and thereafter into the deep sea bay where the historical town of Sibenik
is situated. The river partly flows through a deep canyon carved into a limestone plateau and partly forms lakes.
Among the numerous waterfalls of particular beauty are the Skradinski buk and the Roški slap between which the rivers forms a lake where is situated the Island of Visovac with its remarkable Fransiscan monastery.
