PLITVICKA JEZERA (PLITVICE LAKES), are the most known Croatian national park and are entered in the UNESCO Register of World Natural Heritage. Sixteen little lakes interconnected with waterfalls created by deposition of travertine, a special kind of limestone, constitute the main attraction of this unique park. The park includes the spring of the Korana River in the area surrounded by dense forests of beech, fir and spruce, partly in the form of primeval virgin forest. Apart from the lakes and forests, the Park is ornamented with several caves, springs, flower meadows, and is inhabited by brown bear, among other animal species. The popularity of this park is also in the use of special vehicle for transporting visitors (panoramic trains and electric boats), and is conveniently situated at the main road from Zagreb to Dalmatia.
