I'll put up the location map by next week. Forgot where I put the map..have to look for it first... sorry. But to tell you roughly where it is,
Bukit Enggang is somewhere near Bandar Sungai Long. If you are from KL using Cheras - Kajang highway, the exit is right after Grand Saga tol. You have to pass by Bandar Sungai Long gate, and then go straight up until you reach Bandar Sg Long School. Then go further up until you'll see a gate to Bukit Enggang. Just tell the guards (Indonesian guys -- not uniform-wearing security guards) that you want to look at the land. Insyallah they'll let you in.
