At 360ft high and 1 mile wide they are the biggest falls in the world. Niagra Falls is less than half as high just to give you a perspective of the size of these falls. I am so happy to have seen this world wonder in my life --I would love to go back to see and hear it just one more time. The falls are located on the Zambia/ Zimbabwe border. When I was there it was the Zambia/ Rhodesia border.
