The unity and harmony of the 16 lakes here and their rare natural and cultural value is not only famous throughout Croatia, but also worldwide; earning this remarkable national park a coveted place on UNESCO's list of World Heritage sites.

The path takes us first across Gornja Jezera (Upper Lakes),a system of 12 lakes separated by travertine barriers. Then it's time for a peaceful boat ride towards the second area called Donja Jezera (Lower Lakes), placed in a limestone canyon. Wherever you are in Pltivice it's easy to see why its travertine marble formations are such an extraordinary natural phenomenon. The barriers, sills and other forms created in these lakes, karst rivers and streams are stil an ongoing process that shapes the wonderful landscapes that make your walk through the park so enjoyable. Its these same travertine formations that have and are still creating the  numerous magnificent waterfalls here. This constant evolution makes the Plitvice Lakes never look the same.
