The most prominent and most visited among the eight national parks in Croatia - Plitvice Lakes, is only natural in a society's cultural values, in Croatia included in the World Heritage List (UNESCO) and it still 1979th was among the first in the world.

Possible activities in the park are hiking, climbing, driving an electric boat and train, photography, biking, skiing and boating.

Area Plitvice Lakes National Park is part of the Dinaric karst area that is characterized by carbonate geology background, a number of karst forms, the rare occurrence of surface flow, and expressed surface-underground connection through numerous cracks. Plenty of water and creating lakes in this end of the remarkable and valuable phenomena.
     
An important role in the entire system has a collection area that supplies water lakes. It is highly permeable with a number of underground (caves and pits) and surface karst formations (sinkholes or sinkhole and field), but poor surface flows. The limestone peaks rising just in this area, and the highest - Seliški peak, 1279 m. After the way through the underground water encounters an obstacle - an impermeable rock with which expires at the surface, forming many streams, which enrich the lake. The most important sources of black and white river. On the basis formed the Upper Lakes: Prošćansko Lake Ciginovac, Okrugljak, Batinovac, Big Lake, Small Lake, Vir, Galovac, Milino Lake Gradinsko Lake, the largest and Burgeti plitvice lakes - Kozjak. Lower lakes: Milanovac, Gavanovac, Kaluđerovac and Novakovic Brod, limestone canyon in the concave surface, part of the propusnog areas, where water sinks and is lost through the many cracks in the underground. On the surface of the mesh network of many cells called the valley as a "tower" rising limestone blocks.
Plitvice water streams down through the rocks, forming high 78 mi amphitheater Great falls highest waterfall in Croatia, along with the water forming a lake Slapište essays which begin river Korana.

Systematic studies of the flora of higher plants that have started quite late in 1984. Confirmed that Park Plitvice in terms of richness and diversity of the flora of higher plants represents a sort of phenomenon. On a relatively small area of the park recorded a 1267 plant species grouped in 112 families.

Geographical location (60km from the sea air) in the hinterland of Velebit, on the border between continental and maritime precipitation regime, at an altitude of 418-1279 m, and geological base which is reflected in a number of karst features have enabled the development of reciprocal action by the rich and diverse flora world. Park space is abundant endemic species and the narrow spread wide (72 species).

When it comes to the animal world, Plitvice Lakes National Park, the first association of its trademark - the bear.
Insects, which are among najzastupljenijim number of species in terrestrial habitats are further attracted the interest of biologists - the researchers the habitat of meadows and forests. Deserved the attention received by a group whose number of butterfly species known to the current research has climbed to 321, of which 76 species danjih, and 245 species of butterflies night.
Fauna of birds from far recorded 157 species are in third place in the number of species within the national parks in Croatia.
The Plitvice Lakes National Park is noted for more than 50 species of mammals: puhovi, shrew, voluharice, hedgehog, marten, marten, wild boar, etc.
Recent research has identified 20 species of bats - which live in different habitats, holes and caves, then under the bark of trees in the sockets, etc.
Particular interest is often the population of wolves, deer, deer, wild cat, lynx, otters, brown bears, and of course, from the beginning of the story, as the crown Plitvice animal kingdom.
