Holiday Ayo - Victoria Falls (Lozi: Mosi-oa-Tunya, "The Smoke That Thunders"; Tonga: Shungu Namutitima, "Boiling Water") is a waterfall on the Zambezi River in southern Africa, which provides habitat for several unique species of plants and animals.

It is located on the border between Zambia and Zimbabwe and is considered to be one of the world's largest waterfalls due to its width of 1,708 m (5,604 ft).

David Livingstone, the Scottish missionary and explorer, is believed to have been the first European to view the 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 near the Zambian shore.

Livingstone named his sighting in honour of Queen Victoria, but the Sotho language name, Mosi-oa-Tunya—"The Smoke That Thunders"—continues in common usage. The World Heritage List officially recognises both names.

Livingstone also cited an older name, Seongo or Chongwe, which means "The Place of the Rainbow", as a result of the constant spray.

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.

While it is neither the highest nor the widest waterfall in the world, the Victoria Falls are classified as the largest, based on its combined width of 1,708 metres (5,604 ft) and height of 108 metres (354 ft), resulting in the world's largest sheet of falling water. The Victoria Falls are roughly twice the height of North America's Niagara Fallsand well over twice its width.

For a considerable distance upstream from the falls, the Zambezi flows over a level sheet of basalt, in a shallow valley, bounded by low and distant sandstone hills. The river's course is dotted with numerous tree-covered islands, which increase in number as the river approaches the falls. There are no mountains, escarpments, or deep valleys; only a flat plateu extending hundreds of kilometres in all directions.

The falls are formed as the full width of the river plummets in a single vertical drop into a transverse chasm 1,708 metres (5,604 ft) wide, carved by its waters along a fracture zone in the basalt plateau. The depth of the chasm, called the First Gorge, varies from 80 metres (260 ft) at its western end to 108 metres (354 ft) in the centre. The only outlet to the First Gorge is a 110-metre-wide (360 ft) gap about two-thirds of the way across the width of the falls from the western end. The whole volume of the river pours into the Victoria Falls gorges from this narrow cleft.
