Established in 1985, the Krka National Park (Nacionalni Park Krka) protects the ecologically important area around the middle and lower sections of the River Krka. 

As the river flows down from the upper reaches, it meets a series of lakes and rapids, as well as the beautiful Roski Slap and Skradinski Buk waterfalls.

 At the center of the park is Lake Visovac, just below the Roski Slap waterfalls, and from here, the Krka River joins up with the River Cikola before flowing over Skradinski Buk and out to sea.
