From the peak, find your way that leads to this waterfall. You can ask the local passerby for direction, of look for a sign that leads to it. Go towards exit on Trail A, but take a right turn before you reach there.
You will have to pass your way to the track similar to the one you use to come here, just that, to reach here, you will have to climb upwards, go downwards, till you reach a small river, continue this path, climb upwards ( again ), then go downwards until you reach this waterfall.
It would probably took you 30 minutes to reach here. Though sound like quite a while, but trust me, its worth it.
The surround is beautiful. The water is cold and clear, and the feeling of the a strong breeze coming from the falling water, really makes you feel like you want to stay there for quite a while.
Do come to this place if you have the chance. Where else can you find a nice jungle and a beautiful waterfall that still exist in this urban town of Kuala Lumpur ? This place is suitable for you to bring your family and friends, or even, make it a place for your weekly town escape.
