Got the bus at Gold Reef City in Johannesburg and then you travel around and within the Johannesburg CBD to 12 different stops featuring places of interest. Places such as museums and historical sites in the city of Johannesburg. It is a tremendous amount of fun and everyone visiting the city or even if you live in Johannesburg should do this at least once.
Nelson Mandela Bridge
One of the stops is the James Hall Museum of Transport - a must for boys, young and old and the girls will love it too.
This museum is worth checking out simply for it's huge selection of trasport items from animal drawn carriages to fire engines of old and motor cycles and cars from years ago. Well worth the stop.
