Plitvice Lakes

Plitvice Lakes is a World Heritage Site and National Park in Croatia. 
Waters flowing over the limestone and chalk have deposited minerals, and created natural dams. The result is a series of beautiful lakes, caves and waterfalls. The forests in the park are home to bears, wolves and many rare birds.
Plitvice is the oldest national park in southeast Europe and the largest national park in Croatia. It was founded in 1949 and is in the mountainous karst area of central Croatia, at the border with Bosnia and Herzegovina.
In 1979, Plitvice Lakes was one of the first natural sites added to the UNESCO World Heritage register. Each year, more than 900,000 visitors are recorded.
The lakes are renowned for their distinctive colours, ranging from azure to green, grey or blue. The colours change constantly depending on the quantity of minerals or organisms in the water and the angle of sunlight.
