Ngwenya is one of the world’s oldest known mines. The Visitors Centre has an interesting display of photographs and information, including the original excavation tools. To visit the mine, even if you are travelling by vehicle, you’ll need to be accompanied by a ranger, who will explain the mine's history (note: tips appreciated). The entrance is signposted off the MR3.
Although the mine is part of Malolotja Nature Reserve, you can’t continue on into the rest of Malolotja from here.
