Samy Vellu way - Go North on PLUS, take the Tanjung Malim exit (or exit 121 whatever name its given). Look for signs to Kuala Kubu Baru(Its still quite a drive from the toll, around 12+km). ull be heading roughly south and pass thru Kerling along the way. Near the junction to KKB, there is a small petrol station with quite a large paved area. After this petrol station u should be turning left. Follow the road until u reach KKB town. Near the town proper, more exactly when u start seeing signs for municipal buildings, there's a cross junction with counter display traffic lights. Fraser's Hill is straight ahead.
If u came from Selayang-Rawang-Serendah (old state road), u would have come from the left; meaning that u have to turn right to Fraser's instead of going straight. This starts from Jln Kuching, all the way thru Selayang, straight thru Templer Park, Rawang. Dont turn to Bkt Beruntung near Sg Choh, just keep going straight, basically heading for Tanjung Malim. After Serendah ull have to start being aware of the sign pointing to KKB, bcoz if u miss it ull have to turn back the long way round from an alternate junction. The last time i went there the signboards were adequate so i wish u the same luck. Just follow the signboards and milestones; u should arrive at the KKB town cross junction traffic light like i mentioned earlier. This time, Fraser's Hill is a turn right.
Tight narrow road with a beautiful view of a dam lake early on, the climb is easy and never too steep. Tons of blind hairpins and very2 similar to Genting Sempah route. Massive fun. The climb normally takes 45min-1 hour at casual pace. The Gap lets vehicles climb n descend alternately every hour, altho there is rumor that a new back road has been constructed several km further up (towards Raub direction).
Have a nice time there!
