Take MRT from Toa Payoh to Yishun then transfer to Service 169.
"Journey should take about 15-20 mins (non peak) and look out on
the right hand side. Along the way you will pass a few camp area.
On the left you will see Kabit camp, then further down you will see
Sembawang Air base on you right, about another 5 min you will see
HQ 22SIB on the right again (although you are most likely to miss
this as it is not that obvious) Then another 5-10mins, you will see
a 6DIV Engineering on the right, that is where you press to alight
and after the traffic junction, alight at the bus stop. Cross the
road and follow a small road (at the junction) uphill... and
you are at Nee Soon Camp.
