Ray,
I think CC&C site is a really good spot, in the past we have stopped at 'Little Switzerland a couple of times which is more or less above the CC&C site on the other side of the railway line, I've had a look down there on one occasion and if two caravans don't come head too head I think it would be ok to drive down with a caravan, someone in front with a Red flag may be, 🙂
