What Plitvice is most famous for is it's 16 interlocking kiwi-colored lakes and countless waterfalls varying in height from 6 inches to 300 feet. The science behind this unbelievable beauty is that the flowing water pulls nutrients from the limestone and chalk valley walls and, over thousands of years, deposited travertine barriers, creating natural dams which in turn have created a series of beautiful lakes, caves and waterfalls.
