What Makes Plitvice Lakes Extraordinary

Question

Accepted Answer

Plitvice Lakes National Park (Nacionalni park Plitvička jezera) protects a chain of 16 terraced karst lakes linked by 92 waterfalls, set within a deep forested canyon in the Lika region of central Croatia. The water changes colour constantly — emerald green in the shallower upper lakes, turquoise and deep azure in the lower pools — because of calcium carbonate and magnesium dissolved in the water. These minerals precipitate as travertine (a form of limestone) on mosses and algae, forming the natural barriers between lakes. New barriers are still forming today; the waterfall system is alive and growing. The park covers 296.85 km² and was established in 1949, becoming Croatia's first national park. UNESCO inscribed it as a World Heritage Site in 1979, citing the exceptional natural beauty and the ongoing geological processes. In 2025 it received over 1.5 million visitors — a record. The park's signature feature is the 78-metre Veliki Slap (Great Waterfall), Croatia's tallest waterfall, which plunges from a clifftop at the edge of the Lower Lakes. The combination of wooden boardwalks threading centimetres above the water surface, electric boats crossing the widest lake, and panoramic viewpoints over the cascades makes Plitvice visually unlike anything else in Europe. Swimming is strictly prohibited to protect the delicate ecosystem, but that prohibition has done nothing to diminish Plitvice's status as Croatia's single most-visited natural attraction.
