Overview
Tugela Falls is a complex of seasonal waterfalls located in the Drakensberg (Dragon's Mountains) of Royal Natal National Park in KwaZulu-Natal Province, Republic of South Africa. According to some measurements, it is the world's tallest waterfall. A revisited validation of waterfall measurements is not available, and there's still uncertainty whether Tugela or Venezuela's Angel Falls is the tallest (both measurements were taken at considerable distance from the two waterfalls).
The combined total drop of its five distinct free-leaping falls is officially . In 2016, however, a Czech scientific expedition took new measurements, making the falls tall. The data were sent to the World Waterfall Database for confirmation. The source of the Tugela River (Zulu for 'sudden') is the Mont-Aux-Sources plateau which extends several kilometres beyond the Amphitheatre escarpment from which the falls drop.
Height controversy
There is an argument that Tugela Falls is the tallest waterfall in the world, rather than the more commonly cited Angel Falls. This argument is based on two likely inaccuracies regarding the presumed heights of the respective falls.
