Krka National Park is located near Šibenik and streches downstream of river Krka across the area of 109 km2. The climate is Mediterranean and sub-Mediterranean.
The river Krka has its source at the foot of the Dinara Mountain, north-east of Knin. The river water is partly fresh and partly brackish. The mixing of waters creates a specific habitat to living organisms distinct from the ones that live in the sea and rivers.
Krka has seven tufa falls with the total height of 242m. It is the natural and karst phenomenon forcing its way through krast rocks and deep canyons towards the sea, on its 72 m way.
