River Krka is a phenomenon which forms many lakes, falls and water currents. The National Park that flows along its banks encompasses an area of 109 km2 and follows it nearly 2 km down from Knin to Skradin, a witness to twelve water falls. The most impressive and most visited ones are Skradinski buk and Roški slap. Roški slap is very accessible and can be visited year round. The left bank hosts a number of mills used for processing wheat and corn, some of which are still in use today.
The river Krka is rich with various endemic species of fish. The National Park is also celebrated by bird watchers as a haven and one of the most valuable birding areas in Europe. The park can be visited by boat or from Skradin by foot.
