Exit from Bentong and go towards Bentong town. After Bentong town, look for the signbaord that states Air Terjun Cha Mang. Turn left once you spotted the signboard. You need to drive abt 10KM to the inner road. On the way, you can see alot of durian trees.
Worth visiting if you are in Bentong. Don't bother visiting the hot spring at Bentong. The hot spring is poorly maintain and hardly anyone use it. You don't even dare to put your feet in to the water as you see strange stuff floating on top of the water.
You can also drop by for local ice cream, the row of shops after The Store known as Kedai Kopi Kow Po.This is a well known home made ice cream in Bentong and you can see alot of tourist drop by at this place. Try their cendol with durian ice cream is very nice.
You can stopby at the road side store for durian before you exit to Kuala Lumpur Highway.
