Durban is the chief seaport and largest city of KwaZulu/Natal province of South Africa. It is situated on Natal Bay on the shores of the Indian Ocean and has a population of around 750,000. Durban's harbour is one of the world's major commercial ports and it is a major container port and point of entry for bulk raw materials, capital goods, and industrial equipment. Minerals, coal, sugar, and grain are exported, and oil is refined and piped to Johannesburg.  The city is the headquarters of South Africa's sugar industry and a centre of highly diversified manufacturing activity. Tourism is important and is based on the city's proximity to KwaZulu/Natal's game and nature reserves and on the beaches and their facilities, such as an esplanade and an oceanarium.
