Part of an extended series of 20 caches on a walk of 4-5 miles around Grantchester.
Terrain is flat and mostly gravel tracks and bridleways: everything can be cycled comfortably except the first 50 yards or so from the road past cache 01, but be warned that parts are likely to be muddy, even in good weather.
For parking options, see cache 01.
This cache is a disguised nano, and is only (sensibly) accessible from the northern side of the fence. Note that the fence looks new but was actually installed in early 2017; the cache is accessible without crossing it.
