Hi! I am planning on travelling to Johannesburg this summer. I plan on volunteering at a well established school in a suburb out of the city for my time there. I also plan on visiting my friend who lives out there. However I am feeling uneasy about travelling alone as I understand the city is not the safest place. But I do plan on being busy in the school and spending time with native south Africans who live in the city. Do people think this is a wise idea? Does anyone have experiences of being in Johannesburg?
