The Krka National Park is located entirely within the territory of Šibenik-Knin County and encompasses an area of 109 square kilometers along the Krka River: two kilometers downriver from Knin to Skradin and the lower part of the river Čikola. The Krka National Park is a spacious, largely unchanged region of exceptional and multifaceted natural value, and includes one or more preserved or insignificantly altered ecosystems.
Skradinski buk is one of the most attractive parts of the park. It is a massive, clear, natural pool with high waterfalls at one end and cascades at the other, located in the Krka National Park in Croatia. It is the lowest of the three sets of waterfalls formed along the Krka river. In an area 400 m in length and 100 m in width there are 17 waterfalls and the total difference in height between the first and
the last falls is 47.7 m. Due to the wealth and variety of geomorphological forms, vegetation, and the various effects caused by the play of light on the whirlpools, Skradinski buk is considered
to be one of the most beautiful calcium carbonate waterfalls in Europe.
The rate of flow is 43 m3 a second in winter, 18 m3 in summer, with an average of 55 cubic metres a second flowing down Skradinski buk annually. It is the largesttravertine cascade system in Europe.
Swimming is allowed only in authorised zones, the park can be visited by boat or from Skradin by foot. Entry to National Park Krka is in the town Skradi. Ticket prices for entrance into the nature park is from 25 to 80kn, and for children 7-14 years from 15 to 65 kn.
