From Stump, continue to the road. Turn right and along to
the old red sandstone of the ex-railway bridge, then the bridleway
on the left. Through the gate, under the transmission pylon
and along the lane to the next gate. Keep right along the
fence to the next gate, which you do want to go through despite an
absence of signs. Then it's straight ahead on the east side
of the hedge to join the path to Low Dykes. Keep straight on
to the small 'ford' and just before is the cache site.
Watch out for sharp bits on the floor if you kneel down.
