Vaalwater is a small town situate on the Mokolo River in the Limpopo province of South Africa. It lies at the southern edge of the rugged Waterberg Massif, which is a biosphere that contains considerable biodiversity, including numerous large mammals (e.g. Giraffe, White Rhino, Blue Wildebeest). Waterberg is the first region in the northern part of South Africa to be named as a Biosphere Reserve by UNESCO. The extensive rock formation was shaped by hundreds of millions of years of riverine erosion to yield diverse bluff and butte landform.
