During 1923, the first large groups of tourists started visiting the Sabie Game Reserve, but only as part of the South African Railways' popular "Round in Nine" tours. The tourist trains used the Selati railway line between Komatipoort on the Mozambican border and Tzaneen in Limpopo Province. The tour included an overnight stop at Sabie Bridge (now Skukuza) and a short walk, escorted by armed rangers, into the bush. It soon became a highlight of the tour and it gave valuable support for the campaign to proclaim the Sabie Game Reserve as a national park.
