There are two 'groups' of caches in the series that can be done from the Parking Waypoint:
1. GC4F7Z0, GC4F831, GC4F7YE, GC4E3XA
NB: After doing GC4E3XA, return via GC4F7YE to the Parking Waypoint
2. GC4FMRD, GC4FMQN, GC4FMRC, GC4F7ZF, GC4EA0N
NB: It is best to do this group in the listed order and retrace your steps back to the Parking Waypoint ... you are NOT advised to take a direct route between GC4E3XA and the Parking Waypoint (CO has done this, but not in tick season).
There are also some other accessible caches in this area.
The Gnome Hunters
This series pays tribute to cachers who have completed the Serpentine Gnomes series and celebrates some of the great logs written by said Gnome Hunters.
GrumpyBump
GrumpyBump on all of the Serpentine Gnomes: " 
... on arrival at GZ I had the cache in hand in a matter of minutes ...".
Hmmm ... where I have read those words before?
The Cache
There are remnants of a track near here. Where the track began or ended, I have no idea. I came across the track on my way to this place from ... another cache ... and I followed it a little way. In days gone by, you might have been able to park within metres of the cache and have it in hand within seconds.
