Tourism is becoming increasingly important to South Africa’s economy. While the majority of tourists come from African countries, an increasing number of arrivals are from Europe and the Americas. There are many tourist attractions, notably the national and transnational parks. Travel across South Africa’s borders into other African countries is being eased. Among the most popular tourist attractions are the wine regions in Western Cape province, Table Mountain, Robben Island (designated a UNESCO World Heritage site in 1999; the location of an infamous prison), and historic sites such as the former diamond mine in Kimberley, the Vredefort Dome (designated a UNESCO World Heritage site in 2005; the world’s oldest and largest meteorite impact site), and the Mapungubwe settlement area (designated a UNESCO World Heritage site in 2003; the ruins of an important kingdom of the Iron Age). Ecotourism is increasing in popularity, as is village tourism, in which visitors can learn about traditional rural culture.
