GENERAL INFORMATION ON 2530 BD MBOMBELA The city of Mbombela is situated in the eastern part of South Africa and is the capital of Mpumalanga Province. The city is built on the fertile, flat valley floor of the Crocodile River where there is ample water supply from the river. The city serves as a gateway to some of the best eco and adventure activities in Southern Africa and with its moderate climate it becomes a preferred tourist destination all year round. The sub-tropical fruits like mangos, avocados, oranges, lemons, lychees and bananas are grown in the surrounding Lowveld region. For shopping enthusiasts the city offers world-class shopping malls, casinos and entertainment venues and a convenient stopover to the Kruger Park. The location of Mbombela creates excellent opportunities for prospective investors and businesses to establish themselves in the area along the N4 transport route servicing the Maputo Spacial Development Corridor.
