The 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 was proclaimed a national park in 1985 and is the seventh national park in Croatia. The Krka National Park is located entirely within the territory of Šibnik-Knin County and encompasses an area of 109 square kilometers along the Krka River.

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. With its seven travertine waterfalls and a total drop of 242 meters, the Krka River is a natural and karstic phenomenon.
Between Skradinski Buk and Roški Slap is Visovac Lake with an islet on which there is a Franciscan monastery with a small church. Downstream of Skradinski Buk is the Krka River estuary in which freshwater mixes with saltwater. Part of the estuary is also Prokljansko Lake. The park visitors may see the water mills in which cereals are ground with millstones and taste bread made of such ground cereals. The National Park may be reached from Skradin by boat, or by car to the entrance of Lozovac. From here buses take visitors to Skradinski Buk.
