Named after the Krka River, the Park covers an area of just over 142 square km and includes two thirds of the river itself. The top attraction of the Park are its magnificent waterfalls, including the famous Skradinski Buk falls, the longest waterfall on the Krkr River and are one of Croatia’s most famous sights. The cascades are composed of travertine barriers, islands, and lakes. Other highlights include the small island of Visovac and Roski Slap waterfall. A boat trip through the park (included in the entrance ticket) is a great way of seeing much of the Park. Best of all, it is possible to swim in some locations in Krka National Park!
