I think I have found the foot path, but it seem rarely used these days as it is sort of overgrown. It is just about twenty to thirty steps up hill from the pavilion, right at the place where the main path widen into a concrete service road. If you look to your right you should be able to see it, it would be difficult to miss.
Once again, when I was there earlier today it was already 1700 hrs, with less than an hour to sunset. I am not equipped to scramble up anyway. You would probably need long trousers, long sleeve tops or even gloves. I do hope there would be no nasty things like snakes, bees/wasps and fire ants.
