Kaieteur Falls, Guyana, Kaieteur National Park

Kaieteur Falls is a waterfall on the Potaro River in Kaieteur National Park, central Essequibo Territory, Guyana. It is 226 metres high when measured from its plunge over a sandstone and conglomerate cliff to the first break. It then flows over a series of steep cascades that, when included in the measurements, bring the total height to 251 metres. While many falls have greater height, few have the combination of height and water volume, and the falls are among the most powerful waterfalls in the world with an average flow rate of 663 cubic metres per second.
Kaieteur Falls is about four times higher than the Niagara Falls.
