Johannesburg began as a gold mining camp in 1886. Today, it is South Africa's largest city and its economic engine, still known by the name locals gave it more than a century ago: the City of Gold. For UK travellers planning a trip to South Africa, Johannesburg often works as the gateway: the first stop before a safari or a deeper look at the country's history.
This guide covers where that gold rush history came from, the attractions that tell the story best, and the practical details you need: when to go, how to get there, where to stay, and how to stay safe. At TravelApp, we book low flights to Johannesburg and South Africa holidays every day, so we've built this guide around what UK travellers actually ask us.
In 1886, George Harrison discovered gold on a farm named Langlaagte. This farm is located on the Witwatersrand ridge in today's Gauteng province. Word spread fast. Within months, thousands of miners had set up camp, and by October that year, the settlement had a name: Johannesburg.
The city grew at a startling rate. In just ten years, its population grew past 100,000. This was much quicker than Cape Town's growth over two centuries. Today, the wider Johannesburg metro area is home to around 15 million people.
Historians estimate the Witwatersrand basin has produced roughly 30-40% of all the gold ever mined on Earth. That's why it’s called the City of Gold. Johannesburg now thrives on finance and services. It houses the Johannesburg Stock Exchange, the largest in Africa.
Gold Reef City sits on top of a former working gold mine. Alongside the rides, you can tour an actual mine shaft and see how 19th-century miners worked a good half-day stop, especially with kids.
A few kilometers away, the Apartheid Museum explores South Africa's tough recent history. It traces the system from its beginning to Nelson Mandela's release and the first democratic elections in 1994. It's open Tuesday to Sunday, 9am to 5pm, and most visitors need around two hours. It's not a light visit, but it's one of the country's most important museums.
Soweto is South Africa's biggest township. It was key in the fight against apartheid. Vilakazi Street is unique. It’s the only street in the world where two Nobel Peace Prize winners lived: Nelson Mandela and Desmond Tutu. Guided tours mix history with food, music, and conversations with local residents.
Johannesburg sits high on the Highveld plateau, so its climate differs from the coast. Winter (May to September) is dry and sunny, with warm days and cold nights. This is also the best season for safari trips nearby, since thinner bush makes animals easier to spot. Summer runs from November to March. It’s warm and wet, with brief afternoon thunderstorms almost every day. For most UK travellers, April, May, September, and October are ideal. These months have mild temperatures, less rain, and smaller crowds.
Direct flights from London to Johannesburg take around 11 hours and land at O.R. Tambo International Airport, South Africa's busiest. There's not much jet lag. Johannesburg is two hours ahead of the UK in Greenwich Mean Time. During British Summer Time, it's just one hour ahead.

Sandton is Johannesburg's upmarket business district and the most popular base for visitors, with smart hotels, shopping malls and Nelson Mandela Square. It's generally considered the safest area for tourists. Maboneng is a regenerated arts precinct with street murals, galleries and a busy Sunday market. Melville has a laid-back, bohemian feel, with independent cafes and bars along its main strip. Most first-time visitors base themselves in Sandton and take day trips out to Soweto and Maboneng.
Johannesburg is known for crime, which can deter some travelers. However, most visits go smoothly if you follow basic city safety tips. Keep valuables hidden. Use Uber or Bolt instead of street taxis. Also, avoid unfamiliar areas after dark. The city centre and Soweto are best explored on a guided tour rather than alone. Arrange your airport transfer and first night's accommodation before you land. With a bit of planning, you can navigate Johannesburg more safely.
Johannesburg makes a strong start or end point for a wider South African trip. Pair a few days in the city with Cape Town, or head out to a safari in Kruger or Pilanesberg. TravelApp searches South Africa holidays from airports across the UK, with ATOL-protected holiday packages if you'd rather book flights and hotels together.

Johannesburg got its nickname in 1886 when gold was found on the Witwatersrand ridge. The reef was the richest goldfield in the world. Gold transformed the city from a mining camp into South Africa's economic capital.
