Victoria Falls on the Zambezi River is located on the border of Zambia and Zimbabwe. At 1.7 km wide and 108 meters high, it is an extraordinary spectacle as water drops into a narrow, deep abyss. David Livingstone named the falls after Queen Victoria in 1855. Locally, they are still called "Mosi-oa-Tunya", meaning "the smoke that thunders." UNESCO declared the falls a Humanity Heritage Site in 1989, protecting an area of 8,780 hectares.
