Lesotho enclaved within, a 3,000 km coastline and the Orange River: the physical frame of South Africa

Background

South Africa, whose Northern Cape mining expansion and provincial elections are in the news this week, covers a land area of 1,219,602 square kilometres.
The Government of South Africa lists its neighbours as Namibia, Botswana, Zimbabwe, Mozambique and Swaziland, the country now officially named Eswatini, with Lesotho lying entirely within South African territory in the south-east.
Its coastline runs more than 3,000 kilometres, from the Namibian border on the Atlantic, around the southern tip of Africa, to the Mozambican border on the Indian Ocean.
The highest point is in the KwaZulu-Natal Drakensberg, at 3,482 metres above sea level.
The Orange is the largest river; it rises in the Drakensberg, passes through the Lesotho Highlands and flows into the Atlantic, forming the border with Namibia.
The Limpopo is among the other major rivers.
