There is also a Church Micro in Warnham (#20 so one of the originals!), a Cricket Pitch Micro (#23) near the given parking coordinates, and a few caches named after cartoon characters which you can collect in between these ones. Note: some paths can get very muddy at times so appropriate footwear recommended.
There is plenty of parking on street in Warnham or at the Village Hall (see Additional Waypoint at #1).
A nice view from here down over the countryside and Warnham beyond. The path forks downhill just before GZ, but it is sometimes easier underfoot to continue along the top of this and the next field, then dropping down the field side to re-join the main footpath.
