One of South Africa’s most famous sights is Robben Island, located seven kilometers (four miles) to the west of Cape Town. Its history as a prison is almost as old as the first Dutch settlement on the cape—dating back to the 17th century. Today it is a UNESCO World Heritage Site and museum. The tour guides are all former prisoners, and after touring the island’s graveyard and its maximum-security facility, your visit will conclude with a stop at the cell of the island’s most famous prisoner, Nelson Mandela. The half-hour ferry ride to and from the island includes breathtaking views of Cape Town and Table Mountain. Note that there are only three departures daily, from the V&A Waterfront, in low season—at 9 a.m., 11 a.m., and 1 p.m. (In the spring and summer, there is an additional departure at 3 p.m.) You should book your ferry tickets far in advance.
