OMG I used to study in Curtin Miri!!! No wonder sounds so familiar when you said the hike consists of hiking down the hill and back up again hahaha.
My friends and I called it canada hill. lol.
I love hiking there, and enjoyed the sunset thereafter.

anyway, yes you should climb mount k! it's not so much about the physical but more on the mental i must say. haha I almost cried when I reach the peak too!! :P but too exhausted to shed a tear xD
