Hi @confusedbuffalo.

Sorry I see I said West twice. For clarity, everything to the west of the fence is restricted access, and everything to the East is publicly accessible.

For the "restricted access" part on the east, yes, you do need a paid "guide" to go in, and the gates are permanently locked, except when the guide lets people in. I see on their website http://www.mk.org.za/, they refer to this section as "Melville Koppies CENTRAL" which is the western part of Melville Koppies East that I am referring to.

The Eastern side is also fully surrounded by fencing, but there are multiple gates which are open 24/7.
