The Victoria Falls or Mosi-oa-Tunya are one of the world's most spectacular waterfalls. The falls are situated on the Zambezi River, on the border between Zambia and Zimbabwe, and are roughly 1.7 km (1 mile) wide and 128 m (420 ft) high. They are considered a remarkable spectacle because of the peculiar narrow slot-like chasm into which the water falls, so one can view the falls face-on.

David Livingstone, the Scottish explorer, visited the falls in 1855 and renamed them after Queen Victoria, though they were known locally as Mosi-oa-Tunya, the "smoke that thunders". The falls are part of two national parks, Mosi-oa-Tunya National Park in Zambia and Victoria Falls National Park in Zimbabwe, and are one of Southern Africa's major tourist attractions. They are also a UNESCO World Heritage Site.
