I disagree, i went there to stargaze a few weeks back and let me tell ya, its shitty as fark..
at least hundreds of jakuns at 2-3AM in the farking morning making noise, shouting , showing off the flashlights..i decided to never ever go back there ever again,
one of the best place was gunung bunga buah behind hotel sri malaysia genting, about 4 hours of exhausting climb, the view at night is breathtaking and not one soul was there except me and a few of my homies sitting and barbecuing..

I went during weekdays. Only got Nottingham students there.

YMMV

Sound like damn fun bro. Except for the 4 hours of exhausting climb part. Wouldn't want my girlfriend to suffer climbing up. hahaha.

Its amazing, safe to say one of the best experience ever, the climb is 4 hours but if you climb slowly, take breaks..it should take about 5-6 hours but its worth it
Temperature there is gets real cold, at the peak is a great view of both kl in the far and also genting highlands, its awesome to just chill there with a couple of friends at the peak, fire and bbq in the middle..damn syiok

this is a pic i snap about 6am before sunrise
