Plitvice Lakes National Park is one of the oldest national parks in Southeast Europe and the largest national park in Croatia. In 1979, Plitvice Lakes National Park was added to the UNESCO World Heritage list. The waters flowing over the limestone and chalk have, over thousands of years, deposited travertine barriers, creating natural dams which in turn have created a series of beautiful lakes, caves, and waterfalls. These geological processes continue today. The forests in the park are home to bears, wolves, and many rare bird species. No wonder Plitvice Lakes is the most visited National park in Croatia! Stop for a few hours and explore this beautiful park before continuing to Zagreb!
