The beautiful Krka River provides an abundance of natural beauties, scientific unknowns, significant cultural and historical sites and ways of exploiting its endless water in a rocky area which is otherwise dry during the summer. The boundaries of the Krka National Park cover almost the entire freshwater area of the Krka River with all its seven waterfalls. Krka’s magnificent architectural work began 10 000 years ago in a harsh karst region. The sedimentation of calcium carbonate from water creates tufa which produces diverse geomorphological tufa forms. These forms are the main phenomenon and the backbone of today’s hydrogeological and landscape image of the Park. According to the distribution of plant and animal species, the Krka River belongs to the Mediterranean area, which is characterized by extremely rich and diverse flora and fauna due to its peculiar position and the mosaic arrangement of different types of habitats.
