You are looking for a camo specimen tube here.
From here, continue onwards and towards your left slightly. There are 2 stiles on this fence, the one on the right seems to take you into some rather watery ground, whereas the one on the left, seems to be the one to use, and the one I used.
A distinct track here, and eaily crossed today, but take care with youngsters please.
Your next cache is Gargrave West~Wooden
Many congratulations to Belbincolne for his FTF!
