Suddenly my mind is jam with f*cking workload and I couldn't think of any place to recommend but my piece of advice for all the location which you have listed below.

As I am not certain of the age of your kids, it could be one of the factor I would not advice you to go.

Location 1 - Ulu Pangsoon
I believe you are referring to the Lolo campsite. About 1 hour drive from Cheras Batu 9 towards Batu 18. During weekend this place could be pack with campers near to the waterfall. You might find it a little difficult to get a good camping place if you are to go in late. There are certain confusion on the route to Lolo campsite when it come to the number of fork roads if you have never been there before. No problem of doing your own BBQ but no fishes for you unfortunately. It is about 2 hours trek in from the main entrance and shower facility provided near the carpark.

Location 2 - Sg Congkak
On the same way to Pangsoon but end earlier. Very small carpark that could fit around 30-50 cars maximum. Gate will be open by the guards around 7.30-8 AM if I am not mistaken. Plenty of place you to pitch your tent and it should be safe with the number of people there. Trekking are not required most of the time as most will shower by the stream unless you want to hike up slightly higher for example Gunung Chenuang in the same area.

Location 3- Sg Chiling
Location located before the entry point to Frasers Hill. About 0.5 hour from KKB township. Camping and entrance fee will required to pay around RM3-5 per person if not mistaken. Very safe to camp here but I am not sure whether you are allow to do BBQ here since it is a sanctuary. To trek to the waterfall will take up to around 1-1.5 hour. The problem you might face during the hike is there are few river crossing and it might be difficult to do the last river crossing en route to the waterfall if you are beginner. As it is a fish sanctuary, fishing is obviously prohibited.

You could me ask me more details if you need answer.

Ulu Pangsoon no booking system. More like a first come first serve basis.

Near Batu 10 towards the Semenyih Dam (old trunk road to Jelebu if make a left turn), there is another easy trek called Tekala Falls.

I have never been there before but you could give it a try.

Thanks for sharing the picture and let me help you on the camping part.

We need to see the terrain first before setting up the tent to ensure the water does not flow into your tent base if it is raining. Unless you are in a limited constraint terrain, then you have no choice but Sg Congkak should not be an issue.

I am not sure whether you have a sleeping mat as your base to ensure your body stays warm during the night. Another method to ensure you sleep comfortable will be putting a ground sheet below of your tent which could provide you better area for you to put your unnecessary stuff outside of the camp when you are sleeping. Better investment will be an inflatable air mattress which could be 10 times more expensive compare to a mat. At least both methods will prevent you from catching wet during the night.

To choose a right tent, always remember to -1/-2. When it said as a 3 man tent, it is always comfortable with 1, ok for 2, cramp for 3. You could invest in a flysheet to secure your tent to ensure no water leakage comes from the top. Marketing is all about delusion. You could see why some choose to set up hammock instead of tents

Did you camp on Sunday?
Did you see 1 Chinese guy & 2 girls, walk passing by your camp?

Coincidentally, we were there too! Around 8am - 11am.

That's our gang!
We pick random spot for hiking & Congkak is the one we went yesterday (without realizing there is not much to hike).

If the ground got water underneath when I am setting up my tent, I will look for another option.

I did a bit of Google & found the way.
Yes on the leech, we experience it yesterday. Have to stop to check every 5 minutes. And I missed out one well hidden in my pant only discover it when I got home.
