Please be sure to log the movement of trackables (TBs) or geocoins (GCs) via geocaching.com. It's also helpful, rather than just say 'TB in' or 'GC out' etc, to add its name (or short description - but not the unique tracking number) in your log.
Here is a suggested route, which shows other caches you can bag on the way round:
Then do Parnholt loop 1 to 4
Then backtrack for Parnholt 5 to 13
On the way to Parnholt 14 you can do Chilihouse's Battle of Britain (GC23Q3X)
Then it's Parnholt 14 to 17
Please replace all caches as found and log any interesting aspects/photos of your walk round.
