Course

The river flows in a great arc, first zigzagging north and then north-east, then turning east and finally south-east. It serves as a border for about 640 kilometres (398 mi), separating South Africa to the southeast from Botswana to the northwest and Zimbabwe to the north. At the confluence of the Marico River and the Crocodile River, the name becomes the Limpopo River. There are several rapids as the river falls off Southern Africa 's inland escarpment.

The Notwane River is a major tributary of the Limpopo, rising on the edge of the Kalahari Desert in Botswana and flowing in a north-easterly direction. The main tributary of the Limpopo, the Olifants River (Elephant River), contributes around 1,233 million m of water per year. Other major tributaries include the Shashe River, Mzingwane River, Crocodile River, Mwenezi River and Luvuvhu River.

In the north-eastern corner of South Africa the river borders the Kruger National Park. The port town of Xai-Xai, Mozambique, is on the river near the mouth. Below the Olifants, the river is navigable to the sea, though a sandbar prevents access by large ships except at high tide.
