I might be going solo next week. I done it once via Climbathon challenge but din have the time to enjoy the view there..
I have done Chemerung - Berembun - Langsir 3d2n hiking trip there 3 weeks ago. It's a very nice camping place and the waterfall is jawsdropping. the trail is not too difficult. Definitely worthwhile for your first hiking trip

I have done batu Putih last week, it's not extremely difficult either. Except there's tons of leeches, I got at least 15 and lost count after that. The temperature at the natural rock formation cave is very very cold. make sure you have sufficient insulation else you are going to ended up being a frozen stick (my high body fat % doesn't help a lot here =(
The hike is not easy but not to say technical as well, but the view there is nothing to be shout off

After 3 days I went to Ipoh to hike to Bukit Kledang, easy and calm trails. good for training

then I did Mt Irau yesterday, definitely nice place to hike. due to cold weather, first time I hardly even sweat during hiking. Would revisit for sure one day. Very nice and dreamy scene there

hmm irau is very nice..

G.dato i did not reach the summit tht time, but only the stone where u need to start to climb up.
I was almost the last contestant to reach there.. took me 1:15.. =(

i will want to see if this time can do it less than 1hr after many training lately..

Is there any sungai or waterfall that can mandi air after the hike? that time there's some nice public toilet there but I still prefer to soak myself in the water
