The Krka National Park is located in the area of Šibenik-Knin County and covers an area of 109 km² of the most beautiful river Krka and the lower stream of the Čikola River.
The National Park is a spacious, predominantly unchanged area of exceptional and multiple natural values, and includes one or more preserved or slightly modified ecosystems. Its purpose is primarily scientific, cultural, educational and recreational, and for tourists there are also tourist activities.
The flooded part of the Krka River is about 72.5 km long and the length of the 22nd rivers in Croatia. It runs at the foot of the Dinara mountain, 3.5 km northeast of Knin. With seven sedrenic waterfalls and a total fall of 224 m, Krka is a natural and karst phenomenon. The sloping waterfalls of the Krka River are the fundamental phenomenon of this river.
Already in the middle of the 20th century, the need to legally protect the river Krka and its due to the exceptional natural values to be preserved has already been recognized. The initiative for proclaiming the Krka River National Park was launched in 1971, when a spatial plan bearing the name Krka National Park was developed: a development spatial plan. The area from the old Croatian fortresses of Trošenj and Nečven to the Šibenik bridge, including the three and a half kilometers of the river Čikola, with a total area of 142 km², the Parliament of the Republic of Croatia on January 24, 1985 declared the national park. Due to the four urban areas (Skradin, Bilice, Raslin and Zaton), the construction of the Zagreb – Split motorway and the development of tourism and other economic activities in that area, the Parliament of the Republic of Croatia revised the boundaries of the Park in 1997 by the Law on Amendments to the Law on the Proclamation of the Krka National Park . The southern boundary of the Park was moved upstream to Skradinski bridge, and the north to almost Knin. The border of the Krka National Park stretches 50 km along the upper and middle flow of Krka River (two kilometers downstream from Knin to Skradin) and the lower stream of Čikola (covering the mouth of the river and 3,5 km of river canyon) on the territory of Knin, Drniš, Skradin and Šibenik and the municipalities of Ervenika, Kistanja and Promine.
