The Groot Marico River flows through the Marico District in North West Province, roughly three hours by car northwest of Johannesburg and Pretoria. It is a tributary of the Limpopo and is regarded as one of the cleanest rivers in South Africa, with water described as clear and palatable directly from the source.

Paddlers considering the Groot Marico River or the associated Marico Bosveld Dam should be aware of significant wildlife hazards. Crocodiles have been reported moving upriver from a crocodile farm near Madikwe, and hippopotamus have been spotted in the Marico Bosveld Dam's waters, having migrated upriver from Botswana. These are serious safety considerations that should factor heavily into any paddling plans.

The Marico Oog (Eye of Marico), located near Swartruggens in North West Province, is the origin of the Marico River. It is a spring-fed pool with a maximum depth of 12 metres and an average water temperature of 19°C. The water is crystal clear and supports aquatic life including the Marico Minnow, black bass, freshwater prawns, freshwater eels, and kurper. While the Oog is primarily used as a dive site, its exceptional water clarity is notable for anyone on the water.

The Marico Bosveld Dam has been used for small boat sailing, as evidenced by at least one account of a solar-powered sailing dinghy being launched there in the early morning hours. Facilities in the broader area are limited — the nearest shops from some access points can be up to 45 minutes away — so paddlers should plan to be self-sufficient with gear and supplies. The surrounding landscape is African bushveld, and the river valley is described as green and relatively lush compared to the surrounding terrain.
