American videographer Devin Graham shot this waterslide madness, titled “World’s Most Epic Natural Waterslide! In 4K!”.

The action happens at the Rere Rockslide in New Zealand, a smooth, natural rock formation almost 200 feet long, which has an inclination of 30°, over which the Wharekopae River rushes like water in a colossal water slide. The algae that grow on the stones and bedrock in the river offers a little bit of padding, making this slide almost completely safe.
