We might call it the Magnificent Seven: Bilušića buk, Brljan, Manojlovac, Rošnjak, Miljacka slap, Roški slap and Skradinski buk. These are the tufa cascades of the Krka River – for many, the most beautiful blue line of the Dalmatian karst. Gorgeous cascades and thick, rich sound of life given by water. In many of its parts, the Krka’s flow is calm, and its cascades are announced by “silver necklaces” – increasingly thick rippling of water, the color of which turns silver, resembling countless necklaces scattered on the river. The Krka River source is located near the city of Knin, and the river passes through the Knin valley and enters into a canyon. Quite nearby, sixteen kilometers downstream from Knin, is the first place where the Krka River takes a plunge, creating the Bilušića buk cascade over 20 meters high. Through a large portion of its course, the Krka forms lakes. Brljansko Lake ends with the cascade of Brljan. The highest waterfall on the Krka River is Manojlovac, with the total height of 59.6 meters, and with the highest individual cascade reaching over 30 meters. The lake below Roški slap is approximately 300 meters wide, and the surrounding vegetation, mostly reed and sedge, is a refuge for waterfowl. The lake then enters the narrow passage Među gredama. Following that canyon, the Krka River again opens into the Visovac Lake. In the middle of the lake, there is a small island of the same name – a widely recognizable image of the Krka National Park, for it houses a church and a monastery. The area of Skradinski buk is most frequently the main aim of the visitors. It is the biggest cascade on the Krka River, and the richest in water, its flow over seventeen barriers creating a wonderful sight and sound of nature.
