The Big Hole in Kimberley is the largest hand-dug excavation in the world. In 1871, diamonds were discovered at the site and mined manually by prospectors. The Kimberley Tram Service dates from the beginning of the century and still transports passengers from the City Hall to the Mine Museum. Underground mine tours are a big attraction, as are the famous ghost tours, during which many historical buildings are seen from a different perspective. Hand and mechanical diamond-digging by private diggers can be viewed by appointment.
