As regular traveller to East Africa, Johannesburg, or Joburg as it is locally called, seemed like many other large African cities.
I was warned that you have to watch out in several areas and could be easily robbed. A perspective was built around a criminal intensive city. When I did the tour, this perspective was radically changed and I came to deeply appreciate Joburg. I had the most amazing time, excellent historical insights and delicious foods, giving a much deeper insight in Africa than on any other tour I have done in my many travels.
The team of tour guides are professional, learned, and funny. They make sure you feel safe and comfortable. It is definitely worth it's prize.
They showed the places you would otherwise ignore, and connect you to the beautiful history of unity through diversity. A melting pot of cultures, resulting into a city that can inspire the world. After this tour, I became convinced that with these sort of youthful visions combined with historical understanding, Africa will become a paradise.
Do not leave Joburg, or even South Africa for that matter, without experiencing this world-class city tour! It will likely become the highlight of your holiday.
