The Neretva: one of the coldest rivers in the world?
Emerald, fast and shockingly cold even at the height of summer — why the Neretva has earned its icy reputation, and where to feel it for yourself.
Stand on the Old Bridge in Mostar in August, with the stone baking at 38°C, and watch the divers hesitate before they leap. They are not being dramatic. The Neretva below them is astonishingly cold — often only ten or twelve degrees — and it is this shock of cold green water in a Mediterranean landscape that gives the river its near-mythical reputation. You'll hear it called, with a touch of local pride, one of the coldest rivers in the world.
The reason is altitude and speed. The Neretva is born high in the Dinaric mountains and fed by snowmelt and powerful karst springs that pour out of the limestone already frigid. It runs fast through deep canyons, never lingering long enough in the sun to warm up. By the time it reaches Mostar it is still mountain-cold, which is exactly why the leap from the bridge is a rite of nerve as much as skill.
You don't have to dive to feel it. Raft the emerald rapids out of Konjic, dip your feet from a riverside terrace, or simply watch the colour — that improbable, glacial green — change with the light. It is the thread that ties Herzegovina together, and the coldest welcome you'll ever enjoy.
