Johannesburg

Johannesburg - A common arrival city, and jumping off point, Johannesburg (or Jozi to locals) has a newly remodeled and modern airport. Most families, unless visiting someone in Johannesburg, are likely to pass by the city core on their way to sights outside the city or other parts of South Africa.

Here's a several things worth seeing in the suburbs:

Apartheid Museum - An experience for older kids, this museum will provide a first hand experience of apartheid. Before you enter the museum visitors are arbitraritly classified as "white" or "non-white" and must enter through the appropriate entrance. Plus exhibits about the immigrant history of Johanneseburg, racial segregation, protests, and finally democratic elections. Closed on Mondays.
Gold Reef City - Near to the museum is a small amusement park with a gold theme. Take an underground gold mine tour, pan for gold, and learn about the history of gold in Johannesburg. The theme park also has roller coaster rides, animal farmyard, dance and music performances.
African Craft Market (Rosebank) - Located in the suburb of Rosebank, this is a great place for kids to buy arts and crafts from all over Africa - masks, clothing, beaded dolls, jewellry, wooden carvings. Open daily.
