Plitvice Lakes National park

The Plitvice Lakes National Park is a remarkable geological and hydro geological karstic phenomenon. The Plitvica Lakes complex has been declared a National park on April 8, 1949. It is the largest, oldest and most visited Croatian National park. It presents a forested mountainous region with 16 smaller and larger lakes of crystal clear bluish-green color.
The lakes receive water from numerous rivers and streams, and they are interconnected by cascades and waterfalls. Travertine cascading barriers formed  over the past ten thousand years are one of the main characteristics of the Park. Distinct geographical location and specific climate attributed have contributed to the formation of many natural phenomenon and rich biological diversity. Travertine sediments have been formed from the age of Pleistocene until today, in karst sinkholes and depressions between surrounding mountains. The Upper lakes in the south are mainly comprised of Dolomite, while the Lower lakes in the north are limestone.
