The river starts off as the Groot Marico River at the Eye of Marico, near Rustenburg and Swartruggens in the North West Province of South Africa. The source of the river is a large dolomite hole in the ground with clear water, which is also a spectacular scuba diving spot. It flows northwards as the Great Marico (Groot Marico) and further downstream the smaller Klein Marico River joins forces. For a stretch, it is named Madikwene River, but after the Sehubyane River (Sandsloot) joins its left bank, it reverts to the name Marico.
It continues flowing northwards, bending northeastwards and forming the border between South Africa and Botswana. Further downstream the Crocodile River joins the Marico River from the right and the name of the stream after the confluence becomes the Limpopo River.
Marico Eye’ is the largest of these pools and is a popular freshwater diving spot due to the unusual clarity of the water. The Eye is 17 m deep and 40 m wide. Water Lillies grow from the bottom.
