Introduction
Lake Kozjak is the heart of Plitvice Lakes National Park: about 81.5 hectares and some 46 metres deep, the largest and deepest lake in the park, lying between the Upper Lakes (twelve) and the Lower Lakes (four). That it is one lake at all is the work of travertine - a 40-metre barrier that once divided two lakes grew faster downstream, so about 400 years ago the water rose and merged them, the old barrier now about 4 metres under the surface; the bed is impermeable dolomite, so the water never sinks into the karst. Three piers, P1, P2 and P3, are served by open-sided silent electric boats, the main P2-P3 crossing taking about 10-15 minutes, included in the park ticket. From the boat you can see Stefanija's Island near the centre, a small travertine islet named after Crown Princess Stephanie of Belgium's 1888 visit; fish are visible in the exceptionally clear water between forested limestone cliffs, the quietest stretch of water in the park. At the southern end the Burget cascades pour in from Gradinsko Lake. In peak season the P3 pier queues 20-30 minutes between 10:00 and 15:00; coming from Entrance 2 on Route H and boarding at P2 is usually quicker, and wheelchair users can take the boat with staff assistance.
