Ok ok ok.... so some say yes and some say no... What does the Cape Nature website say you must do? I am too moeg to look, so someone else can do the donkey work and post back here...

FACT:
We are struggling to keep our noses clean. So, Princess or Erica, whomever it may be, I will make arrangements for a cottage, or a campsite or whatever, just to remain friendly and approachable and all the good things that hopefully make me nicer to deal with than some twit who beats the place up on a one-wheeled 2 stroke.
BTW, how does one pay for an overnight or two, if you do not phone, or email, a booking?
ITS A NATURE RESERVE!!!!!!!!!! People go there to ESCAPE from all the city shhht... So, play the game better than anybody else, and you will reap the rewards.
Prior arrangement was NOT bullsht... it's the way it was. If it has changed, OK, well and good. But it WAS THE WAY... OK?
So, ease up on the sense of entitlement...

Arriving there in a klomp manne as daytrippers is going to annoy the people in charge. Never mind what you think is your right or not..... just keep it nice and clean and simple... play the game.... forget the macho..
It may be possible to arrive at the gate, seeking to patronise Annetjie Mosterts camp. After all, that is private enterprise. But you still have to access the Reserve in order to get there, and she probably is under obligation to ensure orderly conduct from her visitors, so whichever way you look at it, it makes sense to make a call, especially for an overnighter.
The whole issue is always about rowdy bikers, and in the last few years, about quads. The main road through Gamkaskloof is NOT SUPPOSED TO BE USED AS A DRAG STRIP... it is hallowed territory. So, when just one ass does the brrrppppppp thang, it's curtains for all concerned, and years of goodwill are blown away. (Not that there is much goodwill anymore.)
Regarding the BMW KTM thing.... I suppose it was tongue-in-cheek?

Guess so...

If you were a ranger in green, and you were to cast your eyes on a bright yellow DRZ400, or a silver 1200GSA, one parked at Meestershuis, and the other at Mosterts Cottage.... which would you immediately suspect of hooliganism? Never mind whether he would be right or wrong... The RANGER HAS THE POWER... you need him, he does not need you. Perception is everything, when you are faced with an uphill battle.
Don't piss them off!!
