Grindstone Cave
This series of caves are a 2 hour walk from the Injisuthi camp. There are 5 caves in a row below the the sandstone cliffs stretching for about 1 kilometre. Only 2 of the caves are painted but other than one excellent painting of an eland the paintings are very worn and indistinct. The first 2 caves are not painted and can be slept in. They also have water.
The second cave in the row has a grindstone, a relic of the past. It does not appear to be of Nguni origin as it is round with a square hole in the center so was probably made by early Voortrekkers.
