Victoria Falls is a spectacular sight at any time, not least because its spray, like rain, creates a rainbow when the sun is out.
At night, this rainbow usually vanishes, except when there is a full moon and a clear sky, and when the Zambezi River is at its most thunderous (Jan–Jul). The combination of moon and rainbow is a very romantic one.
Victoria Falls is a waterfall on the Zambezi River in southern Africa, which provides habitat for several unique species of plants and animals. It is located on the border between Zambia and Zimbabwe and is one of the world’s largest waterfalls, with a width of 1708 m (5604 ft).Wikipedia
