Fort Klapperkop is one of four forts that were built near Pretoria at the end of the 19th century, just before the outbreak of the 2nd Anglo-Boer War. It is named after the hill upon which it is situated, which in turn derived its name from the Afrikaans word for Strychnos pungens, a tree which grows natively on the hills in the area. At just 2.2 km long and with a height gain of only 100 metres, this is a minor pass, but the spectacular views over the city of Pretoria and the beautifully preserved fort at the summit make the small effort to get there more than worthwhile.

The road is named the Jan Rissik Drive.
