Korana River: From Plitvice’s Cascades to Historic Towns
Discover the Korana River, one of Croatia’s most scenic rivers. Flowing from the famous Plitvice Lakes through canyons and karst fields to join the Kupa, it blends wild beauty, rich biodiversity, and cultural heritage.
Flowing out of one of the most breathtaking places on Earth—the Plitvice Lakes—the Korana River begins its journey in a rush of emerald waters and crashing waterfalls. But this karst beauty is far more than just a river that carries the legacy of a UNESCO World Heritage site. It carves through lush canyons, nourishes rich ecosystems, and flows past towns steeped in history and folklore. From its dramatic origin to its confluence with the Kupa, the Korana River tells a story of nature’s resilience and cultural memory.
Origin: Born from a Natural Wonder
The Korana River is born at the Sastavci Waterfall, where the powerful waters of the Plitvice Lakes plunge into a deep limestone canyon. This entire region is defined by karst topography—porous rock formations that dissolve and reform over time, creating dramatic sinkholes, caves, and cascading water systems. The river’s name is thought to come from the Proto-Indo-European root “karr”, meaning “stone” or “rock,” which fits its rugged limestone setting.

Course and Geography
Korana flows for 134 kilometers, winding its way from the Plitvice Lakes National Park through narrow gorges, karst fields, and broad river valleys. Along the way, it forms a natural border between Croatia and Bosnia and Herzegovina for about 25 kilometers before turning north into central Croatia. The river eventually meets the Kupa River in the city of Karlovac, forming part of the great Sava basin that drains into the Danube.
Natural Beauty and Biodiversity
The upper Korana valley is defined by spectacular limestone canyons, clear turquoise waters, and waterfalls, including hidden cascades beyond Plitvice’s famous falls. The river supports a rich mosaic of aquatic and riparian habitats, sheltering species like:
- Otters, a flagship species of clean rivers
- Endemic fish, including trout and the elusive Phoxinellus spp.
- Kingfishers and herons, nesting along overgrown banks
- Rare plants growing on karst cliffs and gravel bars
During the summer, the middle and lower parts of the river become popular swimming and recreation areas, especially around Slunj, Rastoke, and Karlovac.
Rastoke: Where Folklore Meets Waterfalls
One of the most iconic places on the Korana is the village of Rastoke, where the river Slunjčica joins Korana in a fairytale setting of water mills, wooden cottages, and cascading falls. Often referred to as the “Small Plitvice,” Rastoke is a perfect example of how human life has coexisted with the power of water. The mills once ground local grain, powered by the relentless current that still tumbles over moss-covered rock steps. Read more about Rastoke
Cultural and Historical Importance
The Korana has long been a lifeline for settlements and trade routes. It was a frontier zone in the Ottoman-Habsburg conflicts, and towns along the river like Karlovac grew as defensive strongholds and cultural centers. Today, remnants of ancient mills, fortresses, and bridges can be found along the riverbanks, whispering stories of the past.
A River to Protect
While the upper reaches near Plitvice remain pristine, the Korana faces environmental pressures downstream—from urban runoff, agriculture, and summer tourism. Water quality monitoring, habitat restoration, and eco-tourism education are key to preserving its unique biodiversity and landscape.
