Plitviče Lakes National Park is a 295-sq.-km forest reserve in central Croatia. It’s known for a chain of 16 terraced lakes, joined by waterfalls, that extend into a limestone canyon. Walkways and hiking trails wind around and across the water, and an electric boat links the 12 upper and 4 lower lakes. The latter are the site of Veliki Slap, a 78m-high waterfall.
The national park is world-famous for its lakes arranged in cascades. Sixteen lakes can be seen from the surface. These lakes are a result of the confluence of several small rivers and subterranean karst rivers. The lakes are all interconnected and follow the water flow. They are separated by natural dams of travertine, which is deposited by the action of moss, algae, and bacteria. The particularly sensitive travertine barriers are the result of an interplay between water, air and plants.
