Kaieteur Falls is a very large waterfall which lays on the Potaro River, Kaieteur National Park in Guyana (not to be confuse with Ghana which is in Africa). Kaieteur Falls drop from a staggering height of 225 meters (more than 4 times the height of Niagara falls). These falls are not the tallest in the world but the joining of the water volume & the height of the drop – together these qualities makes it to be one of the most powerful waterfalls anywhere on the globe.
