Bainskloof Pass is a mountain pass on the regional road between Wellington and Ceres in the Western Cape province of South Africa. The 18 kilometres (11 mi) pass, opened in 1854, was constructed by road engineer Andrew Geddes Bain with the use of convict labour. Originally built for horse-drawn traffic, the pass was later tarred. The pass reaches 594 metres (1,949 ft) at its highest point. Here, the road joins the Witte River, which descends the northern side of the mountains through a precipitous cleft to a stretch of rapids, waterfalls and natural pools. Bainskloof Pass is now a national monument.
