I visited this WHS in March 2018. It started with a very pleasant and beautiful 50 minuts boattrip from V&A Waterfront, then in a bus with a guide (who actually was living on the island with his family) around the island to the prison where Nelson Mandela had been kept for 18 years. Our guide here was also a former ANC prisoner - and it was very interesting but also very sad to hear him speak about his time in jail. At the end of the tour we saw Mandelas prison cell.
The whole island is a museum now - a very interesting WHS and it is very important that we don't forget the history.
