South Africa's economic heart — the Apartheid Museum, Soweto, Constitution Hill and the lively Maboneng quarter.
Johannesburg is the largest city in South Africa and the continent's main economic hub, grown up almost overnight after gold was found on the Witwatersrand ridge. Today it is a varied, energetic and contradictory metropolis, where the towers of the business district sit beside townships, and the memory of apartheid is interwoven with a young creative culture.
Around 5.8 million people live in Johannesburg and the surrounding Gauteng region, and considerably more counting the outer suburbs. The city's history began in 1886, when a prospector found gold-bearing rock; within a few years a tent camp had become an industrial centre. The traces of the gold rush are still visible: the giant mine dumps around the city are among the largest man-made hills on the planet.
Locals affectionately call it Jozi or Joburg. It stands at about 1,750 metres above sea level, so the climate is milder than you might expect in Africa: warm rainy summers with thunderstorms (November to February) and dry sunny winters with cool nights (June to August).
The cooking reflects the country's many faces. Try braai (the local barbecue), bobotie (spiced mince baked under an egg custard), dried biltong, the hearty pairing of pap and vleis (maize porridge with meat), and bunny chow — half a loaf filled with hot curry. Coffee culture is well developed, particularly in renewed districts such as Maboneng.
Johannesburg is the region's largest aviation hub: O. R. Tambo International Airport connects the city with Europe, Asia and the rest of Africa. Within the city, pre-booked taxis and ride-hailing apps are convenient, and the Gautrain express service runs between Johannesburg, the airport and Pretoria.
The tourist areas are safe with sensible care. Avoid displaying valuables, do not walk unfamiliar districts after dark, and visit townships with a guide. The national currency is the South African rand; cards are accepted everywhere, but a small reserve of cash is useful at the markets.
Around three days works well. Give the first to apartheid: the museum and Constitution Hill. Devote the second to Soweto with its historic streets and memorials. The third suits a trip out of town — the Cradle of Humankind or Pretoria — or an unhurried look at the Maboneng and Newtown art quarters.
