Victoria Falls located on the border of Zambia and Zimbabwe is one of the greatest tourist attractions in Africa. It is 1.7 km wide and 108 metres high, with water dropping into a narrow deep chasm. David Livingstone discovered the falls in 1855 and named them after Queen Victoria. Locally they are still called “Mosi-oa-Tunya”, meaning the smoke that thunders. In 1989, UNESCO declared the falls a World Heritage Site protecting an area of 8,780 hectares.
