Option 1: Take the highway to Rawang, get off and turn right after the toll. Go through Rawang town continue on all the way to Batang Kali town. Turn right at the traffic lights ( By the police station ). Keep going straight on. There will be a traffic light signposted left to Genting - do not turn but go straight through the lights at the cross roads and then open your eyes for hash signs on the left its about 1km after the Genting crossroads.
Option 2: Take Jalan Kuching exit to Batu Caves. At the big roundabout go through Batu Caves town and at the traffic lights (mosque on corner) sign posted Ulu Yam turn right and continue on roughly 6 kms.
