Dinara mountain. After meandering through the Krčić canyon, it enters the
karst valley of
Knin through the Krčić waterfall of . At the foot of the second, called the Topoljski waterfall, of these is a spring in a cave with of passage. The river then flows through the valley, where it is fed by the on the left (from the nearby
Kosovo polje) and the and the on the right, passing the
Fortress of Knin between the last two on the way, and into the main canyon. What follows belongs to the
Krka National Park. The first waterfall there is the high Bilušića waterfall, which is followed by twice its height in cascades. They lead to the Brljansko lake with a waterfall in its middle, of nearly equal height. At the end of the second half of the lake begin the Manojlovački waterfalls, a series of waterfalls and cascades with a total elevation of , half of which is from the last one. Here, on the right bank, lie the
Roman ruins of
Burnum. At the far end of the canyon are the ruins of the medieval castles of
Nečven on the left and Trošenj opposite it. Beyond it is the
Serbian Orthodox Krka monastery. Further down, an extensive cascade system ends in the high Roški waterfall. Still further, the river forms the Visovačko lake, with the
Franciscan order Visovac Monastery on the island in the middle of the lake. The lake ends at the confluence of the Krka and its largest tributary, the
Čikola. At that point, they form the Skradinski waterfalls, a long series with a total height of . The river is navigable from the sea up to this point. The river flows past the town of
Skradin on the right, flowing into the wide

Šibenik, which is connected to the
Adriatic Sea by the
