This is a cachers paradise to hide a GC.
We use to walk our dog here and let him loose to go and explore the area, this are is muggle free or so I hope, but the only muggles that you might see are the muggles on the highway, but they will not be able to see what you are doing.
From here you have a nice view over the N12 North and South.
You can come sit here on one of the many rocks, and relax while you watch the hectic traffic.
Hope you enjoy this cache
