Victoria Falls, Zimbabwe/Zambia

Victoria Falls is the largest waterfall by combined width and height, spanning 1,708 m and dropping 108 m into Batoka Gorge. At peak flood from March to May, the Zambezi River thunders at 500,000 m³ per minute, audible 40 km away and visible as a spray plume from 50 km. This torrent is 30% greater than Iguazu Falls' average flow, making Victoria the more thunderous spectacle during the wet season. The Zimbabwe side's knife‑edge walk offers the closest rainbowed views, while the Zambia side's Devil's Pool allows swimming at the lip from August to January. Arrive at dawn to avoid crowds and witness the spray‑lit rainbow casting a 60‑meter arc.
