Neretva - Upper Neretva

The upper course of the Neretva river is simply called the Upper Neretva (Bosnian: Gornja Neretva), and includes vast area around the Neretva, numerous streams and well-springs, three major glacial lakes near the river and more lakes scattered across the mountains of Treskavica and Zelengora in the wider area of the Upper Neretva, mountains, peaks and forests, flora and fauna of the area. All this natural heritage together with the cultural heritage of the Upper Neretva, represents rich and valuable resources of Bosnia and Herzegovina as well as Europe.

The upper course of the Neretva, Upper Neretva has water of Class I purity and is almost certainly the coldest river water in the world, often as low as 7–8 degrees Celsius in the summer months. Rising from the base of the Zelengora and Lebršnik Mountain, Neretva headwaters run in undisturbed rapids and waterfalls, carving steep gorges reaching 600–800 m in depth through this remote and rugged limestone terrain.
