Mac-Mac Falls, Dual-stream waterfall in Mpumalanga, South Africa

Mac-Mac Falls is a waterfall in Mpumalanga, South Africa, where water drops in two parallel streams into a forested gorge. The two cascades fall over steep rock faces surrounded by dense vegetation and deep canyon walls.

In the 19th century, gold prospectors used dynamite on the original single waterfall to gain easier access to the rock beneath. That blast permanently split the falls into the two separate streams visible today.

The falls were declared a Provincial Heritage Site on 18 February 1983, together with the indigenous forest in the kloof below them. Visitors can look for the protected forest that lines the gorge beneath the twin streams, the part of the site covered by the same heritage listing.

A paved path with steps leads from the parking area to a viewing platform that faces the falls directly. The walk is short and manageable for most visitors without any special preparation.

Although the dynamite blast by prospectors seems like an act of destruction, the two resulting streams have over time developed their own separate water channels and small habitats. This makes the site a rare example where a 19th-century human intervention permanently and visibly reshaped the natural landscape.
