Do I need a visa to enter South Africa?

No, you don’t need this. Only an international passport is required.

Parents travelling to South Africa with children under the age of 18 must carry a copy of the child’s birth certificate in English from 1 June 2015. Ask your local authority for a multilingual extract of the birth certificate, which is also in English. For children under the age of 12, the Kids-ID is accepted as a replacement document. This is also available from your local authority. However, some airlines do not accept the Kids-ID as a replacement document. It is therefore advisable to contact your airline in advance to ensure that you have all the necessary documents. If you are not travelling with both parents, a written authorisation from the parent who is not present is also required, also in English and available from your local authority. You can have the signature legalised at your municipality.
