Kaieteur Falls is a waterfall on the Potaro River in Kaieteur National Park, central Essequibo Territory, Guyana. It is 226 metres (741 ft) 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 (822 ft). 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 (23,400 cubic feet per second).
Kaieteur Falls is about four times higher than the Niagara Falls, on the border between Canada and the United States and about twice the height of the Victoria Falls on the border of Zambia and Zimbabwe in Africa. It is a single drop waterfall and is the 123rd tallest (single and multi-drop waterfall) in the world, according to the World Waterfall Database. The same website lists it as 19th largest waterfall in terms of volume, and in their estimation, Kaieteur is the 26th most scenic waterfall in the world
