Tugela Falls
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. It is generally accepted as the world's second-tallest waterfall but there is an argument that it is actually the tallest waterfall in the world, rather than Venezuela's Angel Falls.
