The path across the field is well defined once at the end there is a nice perch to stop for lunch/break.
The village of Hollingbourne has several spots for parking one being near the church. This is a circular walk, which will be up hill at the start but down at the end if starting at 1. None of the caches are hard to find but do take you to a beautiful area in kent. Along the way you could pick up the much harder/challenging caches GC1M17E PWU #5 and GC3CWZ0 twist and shout both rated 4 and 4.5 difficulty.
