The cache is not at the posted coordinates - follow the directions and you will find it.
A quick park and grab on one of the roads to Nieu Bethesda. We prefer this one as it is gravel all the way. No tar roads for us if possible.
The listed coordinated take you to a milestone (is it now a kilometerstone?).
Walk 11m directly across the road and you will be able to reach for the magnetic cache.
