After leaving Bentong town for a kilometer on the way to Raub, take the left turn towards the direction of the Chinese cemetery. You will see this junction very soon. A 10-kilometer bitumen road, which meanders along the river within its basin, takes visitors to a forest reserve.
If you are longing for ferocious looking falls and dislike trekking or even walking, then Chamang is the right choice. The unyielding rocky hillside resisted the force of the river but finally give in to having a tall vertical drop.
You can make your way up the cascades by moving cautiously on the rock. Be warned - the type of rocks here is well smoothened by the abrasive forces. Fairly good grip when dry. Our advice is- find another waterfall area to do your river trekking.
Outside the car park area, there was an old logging trail, at the spot opposite the signboard for the waterfall. The track will move up the hill slope to an area when the river begins its descend.
The river at this point is approximately 25 meters wide with depth of 0.5 meter to one meter. As the river is in its rapid stage, the flow of water is extremely strong. Only at this tiny patch, visitors get sight of the river, beyond this the river dropped swiftly among the boulders again.
We share his observation. The broad water swept but dry cascade surface looks tempting and challenging for new comer to walk up its slope. Some where in the center of the cascade, are narrow channels for bather to lie in and get messaged. However within one of these, is an underground funnel where the river disappear. Broad enough for human body to be sucked in. The river then joins the large pool again through under ground waterways.
