The Nelson Mandela Gateway to Robben Island, the point of departure from Cape Town's Waterfront for the Robben Island ferry, was officially opened by Nelson Mandela on 1 December 2001.
It is worth booking tickets in advance, as this in one of Cape Town's most popular attractions. Note that when you do they will ask for a phone number – this is because they occasionally have to cancel tours due to bad weather and choppy seas.
