Beyond the main tourist attractions, hidden in a rural area, between Rastoke village and Plitvice Lakes National Park is the Mreznica River. In the canyon, dense forest covers the area, surrounded by cliffs where you can reach the waterfalls only by kayak. The source of the river is only 12 km upstream from civilization but it brings clean drinkable water. Surrounded by untouched nature, the easy rapids and calm waterfalls put this river on the world map, marking it the most beautiful river in Europe. Its local name is actually “The waterfall playground”.
