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 #1, again between 3 & 4 and between 17 & 18 and more parking for the considerate between 10 & 11 in Cockayne Hatley itself so this walk can be split into bitesize chunks if necessary.
If the wind is in the right direction you'll be treated to the sweet smell of human sewage - nom nom!
