If you're following this series in order, from the last cache you'll continue Gull Lane. Take the left onto the next public footpath and over a sleeper bridge over a ditch (the right takes you to Framingham Pigot).
There is some tree cover here which may throw GPS tracking out a little, although we've tested the co-ordinaries a few times to ensure they get you close.
There are a number of goodies to swap if you find this cache.
