The lakes are divided into the Upper Lakes, lying mostly on dolomite, and the Lower Lakes in a limestone canyon, close to the 78-metre Veliki slap, the park’s highest waterfall. Wooden boardwalks lead visitors over and alongside the turquoise water, electric boats cross Lake Kozjak, one of the two largest lakes, and panoramic vehicles link the main points of the park.
Swimming is not permitted, to protect the fragile tufa barriers. Each season brings its own colours, from lush spring greens to autumn gold and, in winter, frozen waterfalls.
