According to Breakingtravelnews.com, increasing numbers of travellers are developing an interest in "the murky underworld of crime and punishment" by combining a beach holiday with a visit to a prison museum.
Those planning a trip to South Africa could make a stop at the infamous Robben Island, where Nelson Mandela spent 27 years of his life.
Now listed as a World Heritage site, the island offers tours of the former maximum security prison along with the chance to speak to former inmates.
According to the museum's website, it provides a "poignant reminder to the newly democratic South Africa of the price paid for freedom".
Those interested in visiting Robben Island can take advantage of discounted tickets.
The museum is currently charging R100 (£7.88) for entrance, the same price as ten years earlier.
