A visa is available free of charge to Dutch and Belgians at the border and is valid for stays shorter than 90 days (tourist visa). You will receive a stamp in your passport at customs at the airport, this is about half a page. Please note that you have enough space for this. The passport must have at least two blank pages and must be valid for at least 30 days after returning to your own country. You must also be in possession of a plane ticket with a confirmed return or transit flight.
From June 2015, children under the age of 18 must also be able to show a birth certificate upon entering South Africa. Additional documents are also required if the child does not travel together with the biological parents (or 1 of the biological parents).
The requirements for a visa are different for every country. Always check this carefully. The best thing to contact the South African Embassy in your home country for more information.
