Victoria Falls, Zimbabwe/Zambia

Victoria Falls (Mosi-oa-Tunya, "The Smoke That Thunders") is the largest waterfall in the world by combined width and height, stretching 1,708 metres across and dropping 108 metres into the Batoka Gorge of the Zambezi River. The volume during peak flood (March–May) reaches 500,000 cubic metres per minute, generating a roar audible 40 kilometres away and a spray cloud visible from 50 kilometres. The best viewing platform is the Zimbabwe side via the knife-edge walk and Rainforest Trail; the Zambia side offers the famous Devil's Pool natural infinity pool at the very lip of the falls (accessible August–January when the water is lower).
