A little known place of interest is the Phalaborwa Copper mine viewpoint about 7 km south of the town along Koper street to the mine entrance. The viewpoint is open to the public during the daytime and gives wonderful views over the "Big Hole ' and surrounding lowveld. A great spot for landscape, sunrise or sunset images.
If you are travelling between Swaziland and Komatipoort a must see, and underrated site is the Samora Machel Monument and Museum at Mbuzini. The site is about 30 km off the R571 along a tarred scenic road alongside the Mozambique border.
