Bainskloof Pass is situated in the Western Cape province of South Africa, on the Regional road R301 between Wellington and Ceres. This 30 kilometer pass was completed in 1853 and is one of the most picturesque passes in the Cape. The pass was built using convict labour, by Andrew Geddes Bain, the most famous of southern Africa’s road engineers. Bain achieved this remarkable feat without any formal training.
At the summit (595 metres (1,952 ft)) are a plantation and picnic ground. 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 was originally built for horse drawn traffic in 1853. Since then the western side has been somewhat altered but the eastern side is pretty much as it was other than it has been tarred. Wikipedia
