The Zambezi River flows quietly across a flat plain - and then suddenly disappears over an enormous cliff. The whole river drops at once. The water hits the bottom so hard that it explodes back upwards as a thick white mist. On a busy day, that mist can rise 400 metres into the sky and be seen from 50 kilometres away.
Because of the mist, a whole little rainforest grows on the opposite cliff. Even when the rest of the area is dry, the spray waters the trees there every single day. Monkeys, baboons, butterflies and bright birds live in this tiny patch of rainforest that only exists because of the falls.
Walking across the bridge in front of the falls is a wet experience. The spray flies sideways and upwards in every direction, so visitors put on raincoats - and they still get soaked. On sunny days, full circle rainbows hang in the mist. At full moon, you can sometimes see a 'moonbow' - a rainbow made by moonlight instead of sunlight.
Victoria Falls is one of the Seven Natural Wonders of the World, and a UNESCO World Heritage Site. The river is shared by Zimbabwe and Zambia, and you can see different parts of the falls from each country. Most visitors agree that the Zimbabwean side gives you the widest, longest view of the whole curtain.
