Plitvice Lakes National Park is one of the oldest and largest national parks in Croatia. In 1979, Plitvice Lakes National Park was inscribed on the UNESCO World Heritage list, due to its outstanding and picturesque series of tufa lakes, caves, connected by waterfalls.

The beauty of the National Park lies in its sixteen lakes, inter-connected by a series of waterfalls, and set in deep woodland populated by deer, bears, wolves, boars and rare bird species.  The National Park covers a total area of 300 square kilometers, whilst the lakes join together over a distance of eight kilometers.

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. The encrusted plants and bacteria accumulate on top of each other, forming travertine barriers which grow at the rate of about 1 cm per year.

Plitvice Lakes isn’t just for summer. It’s a stunning place to visit any time of year as the different seasons see the Park take on different hues, whether that’s lush greenery in spring/summer, rich colors in autumn, or magical scenes in the snow and ice in winter. Even if conditions are rainy, the park can still be wonderful to explore as the water takes on a dramatic effect – sometimes bubbling up underneath your feet on the wooden pathways.

The popularity of this park is also boosted by the special means of transport used to ferry visitors around: the panoramic electric trains and the noiseless electro-powered boats. By a network of paths, visitors can get around and access the numerous waterfalls and the rocky lake shores easily.

Each year, more than 1 million visitors are recorded. The preservation of old customs and traditions is of high significance for the local population. The local culture has also been detected as an important factor for tourism. As regards architecture, the region of Lika is well known for its low wooden houses with roofs made of rye straw or shingles.
