Here's a update since I've already found my way there
myself.
For those who needs to go there for Medical Appointment.
Go to Boon Lay Bus Interchange
Take Bus 241
Alight at the bus stop that
stops directly at the opposite of Juying Primary
School, should be the 8th Stop.
Cross over the road, and walk forward, you should see the camp,
than walk inwards..
Clothes wise will be minimal polo t-shirt with jeans and
sports shoes.. (For NSMan)
There is some distance between the bus-stop to the camp
entrance, and from the entrance to the Medical Centre..
So wear something comfortable while you find your way there.
