This waterfall is easy to get to by road from Kuala Lumpur. Take the Lebuhraya Rawang (route #1) which is basically a continuation of Jalan Ipoh. Heading towards Rawang you will see the park on your right a kilometre after Templer Country Club.
If going on a weekend, get there early as there are limited parking places.

Various travel agents in Kuala Lumpur can arrange tours to the park.
