This cache is hidden near a small bridge on the way up to Bunkers Hill. It can be very muddy at the cache so be sure to bring walking boots or wellies. While you look for this cache, I highly recommend going all the way up to Bunkers Hill, which I have marked as an additional waypoint. The best way to get to this cache is to start the walk from an alleyway along Broadway, which I have marked as an additional waypoint.
The container is a small dark-coloured tupperware box, with enough space for a few bits and bobs.
