Victoria Falls, or Mosi-oa-Tunya (Tokaleya Tonga: The Smoke That Thunders), is a waterfall in southern Africa on the Zambezi River at the border of Zambia and Zimbabwe. It has been described by CNN as one of the Seven Natural Wonders of the world.
David Livingstone, the Scottish missionary and explorer, is believed to have been the first European to view Victoria Falls on 16 November, 1855, from what is now known as Livingstone Island, one of two land masses in the middle of the river, immediately upstream from the falls on the Zambian side. Livingstone named his discovery in honour of Queen Victoria of Britain, but the indigenous Tonga name, Mosi-oa-Tunya—"The Smoke That Thunders"—continues in common usage as well. The World Heritage List officially recognizes both names.
The nearby national park in Zambia is named Mosi-oa-Tunya, whereas the national park and town on the Zimbabwean shore are both named Victoria Falls.
A famous feature is the naturally formed "Armchair" (now sometimes called "Devil's Pool"), near the edge of the falls on Livingstone Island on the Zambian side. When the river flow is at a certain level, usually between September and December, a rock barrier forms an eddy with minimal current, allowing adventurous swimmers to splash around in relative safety a few feet from the point where the water cascades over the falls. Occasional deaths have been reported when people have slipped over the rock barrier.
