Just because a pad is an alternative name for a pen / sty / house...
This is just to the west of the M9 Spur, but you need to walk or cycle to it. Or hop. Or slither. Who am I to give instruction? As far as I can tell though, you need to follow a footpath to get to this one.
At no time should you need to climb any fences to enter fields. The cache is hidden within the borders of the path area. It looked to me that this was as far as the path went though, but it is a pleasant walk.
