Sandi Toksvig goes to Tanzania and sees two very different aspects of the country. In the heart of the southern highlands she goes to the market town of Iringa and hears about a farm that accommodates the overlanders passing through Africa, a cafe that caters for volunteer workers in the area and makes elephant dung paper and a prehistoric site that has stone tools up to 400,000 years old. On her way back to the coast she spots African wild life from the main highway. By contrast the tropical island of Zanzibar has dolphins in the Indian Ocean, monkeys in the mangrove forest and amongst popular attractions for tourists are the spice farms where Sandi's preconceptions are challenged.
