I just finished hiking Bukit tabur yesterday.. we go there unprepared and none of us have knowledge on the hill.. I'm not sure which 1 we go.. but we've gone through Check point 1-11, to the peak then does down using another route. The cliffs are VERY VERY dangerous. We ran out of water supply and almost called for rescue team because we don't know where is the end. for beginner.. please be very careful when u try to climb this.
