The Krka National Park is located in Central Dalmatia and encompasses an area of 109 square kilometers along the Krka River: two kilometers downriver from Knin to Skradin and the lower part of the Čikola River. From the flooded part of the mouth, it is 72.5 kilometers in length, making the Krka the 22nd longest river in Croatia.

The source of the Krka River is at the base of the Dinaric Mountains, 3.5 kilometers northeast of the base of Knin and 22 meters below Topoljski Slap, Veliki Buk and Krčić Slap, which are noisy cascades in the winter but run dry during the summer.

The length of the freshwater section of the river is 49 kilometers and that of the brackish section is 23.5 kilometers. Significant tributaries of the Krka River include Krčić, Kosovčica, Orašnica, Butišnica and Čikola with Vrb. With its seven travertine waterfalls and a total drop of 242 meters, the Krka River is a natural and karstic phenomenon.

Krka National Park is a spacious, largely unchanged region of exceptional and multifaceted natural value, and includes one or more preserved or insignificantly altered ecosystems. It is intended primarily for scientific, cultural, educational, recreational, and tourism activities such as visiting and sightseeing.

It was proclaimed a national park on January 24, 1985.
