South Africa to eSwatini visa requirements

No. South African ordinary passport holders do not need a visa for eSwatini and may stay up to 30 days for tourism. South Africa is on eSwatini's visa-exempt list, both as a SADC member state and a Commonwealth country, so holders of an ordinary South African passport can enter eSwatini for tourism or a short visit without any visa. The standard permitted stay is up to 30 days, granted as a free entry stamp on arrival at the border or airport. This can be extended for a further 30 days at the Ministry of Home Affairs in Mbabane; visits beyond 60 days require a Temporary Residence Permit (TRP). Travelers need a passport valid for at least three months beyond the intended departure date with at least two blank pages, plus proof of onward/return travel and sufficient funds. eSwatini does not currently operate an eVisa or formal visa-on-arrival scheme for the nationalities that require visas (those must apply at an eSwatini mission abroad), but this is irrelevant for South Africans, who are visa-exempt. South Africa and eSwatini share land borders and travel between the two is straightforward; note that eSwatini is a separate sovereign kingdom and not part of South Africa, so an entry/exit stamp is still issued. Carry your physical passport (not just a SADC ID) for international crossing, and keep return tickets and accommodation details accessible in case immigration asks.
