The Sani Pass is the only road crossing between South Africa and the mountain kingdom of Lesotho in the Drakensberg region. The South African side is paved; the Lesotho side is a dramatic, rocky 4WD track climbing 1,300m in 9km. The pass summit sits at 2,874m on the Lesotho plateau. Technically demanding but unmissable.
