The Karlovac Freshwater Aquarium is located by the river Korana. The address is Branka Cavlovica Cavleka 1a, 47000 Karlovac
The exhibition displays the flow of a karst river. It starts on the square with a water surface and continues inside the building with a system of ramps that wind down, underground, into the basement level. Passed the headwaters, sounds of the flowing river quiet down and visitors plunge into caves that feature endemic species. Further on, they arrive to an aquarium with larger specimens of rare species. Out of the cave, the river emerges from the underground back to the surface. As visitors walk into a tunnel that evokes immersion into the river, they can observe, from the sides and then from underneath, fish and aquatic plants living in warmer parts of the riverbed. After the tunnel a new series of aquariums with water lilies and rushes show marshy habitats. The exhibition ends with a system of cascading aquariums whose biotopes display waterfalls and the travertine barrier. Finally, a stairway and an elevator bring visitors passing through the gift shop, back to the entrance hall
