"One of South Africa’s most famous sights, Robben Island is located 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 all the way back to the 17th century. Today, the island is a UNESCO World Heritage site and museum, offering guided tours by former prisoners. After visiting the graveyard and maximum-security facility, guests can finish with a stop at the cell of the island’s most famous prisoner, Nelson Mandela.The half-hour ferry ride to Robben Island includes breathtaking views of Cape Town and Table Mountain. Just note that the ferry only runs three times a day in the low season; in the spring and summer, there’s an additional departure in the late afternoon. Book your tickets far in advance."
