So, here we go:

If you’re coming with Sunway Pyramid behind you, turn right into the housing estate from the Western Digital Traffic lights (for those coming from 1U, Western D will go be on your right).

Go up the road, keep right and take the first right turning you see. Turn left immediately into the housing estate. Now, take the first right turning and follow the road until you can’t (at this point, you should have gone down a hill and be forced to go left and am now confronted with a huge mound of earth).

Turn right here and make a big u-turn. You are now at the park. 😀 It is covered by many creepers.
