There are a few other caches that can be taken in whilst in the vicinity.
There are no refreshment opportunities on the walk but many close by.
There is parking for 1 or 2 near #26, again at #4 and at the Water Tower north of #20 and more parking for the considerate between #11 & #12 in Cockayne Hatley itself; so this walk can be split into bitesize chunks if necessary.
A Small camo tub with room for very small swaps and trackables. Trackable present at time of hiding.
Stick to the footpath, the coordinates might need updating but once near GZ you will see hint item. The coords on google maps look bad compared to what I got at GZ. I will update and consider suggestions from finders.
