The Botterkloof pass is a fairly substantial altitude gaining pass in the Northern Cape between Clanwilliam and Nieuwoudtville. It is the third of a trio of passes on the R364 route for those travelling from West to East. In rainy weather or snow conditions, this pass can become very tricky even in a 4WD vehicle. The origins of the name are not known, but it is probably named after dairy (butter) products being produced on a nearby farm or possibly that the pass becomes as slippery as butter in bad weather; or a third option is that it could be named after the 'Botterboom'.
