The river Krka, a natural phenomenon in rocky terrain, springs at the foot of the mountain Dinara, at the east part of the field of Knin, it flows through a magnificent canyon and empties into the Adriatic Sea near the town of Šibenik. With the flooded part of its mouth the river is 72 km long. In 1985 it became a national park because of its natural, scientific and cultural value. 

A small island of Visovac is definitely a jewel among the sacral values of the national park. It is situated in the middle of a lake also formed by the river and it is a home to an old Franciscan monastery, a valuable historical monument.
