Follow signage to ZamHols (off the North Road out of Marandera). There is an awesome kopje just before the camp itself. You can do this climb with out climbing equipment, but you will need to be VERY careful skirting around the access rock at the top. DO NOT attempt this if it has been raining - the lichen on the rocks make it like ice!
You will see an abseiling bolt near the top of the kopje. (it's not there, but you are at the right level). It's hidden just in front of you after a short climb onto the abseil level.
