The Umzimkulu River is a river in South Africa.[1] It rises in the Drakensberg mountains and flows southeast towards the Indian Ocean, which it enters in Port Shepstone. Towns on the Umzimkulu include Underberg and Umzimkulu. In the past, it formed part of the border between Eastern Cape and Kwazulu-Natal.
In late February of every year, the river is host to one of South Africa's most popular canoe races, the Drak Challenge.
