Once you have the co-ordinates, enjoy the 2 km walk along the
River Stour in the Dedham Vale to the cache, or you can drive to
the National Trust site at Flatford Mill (2 exits north on the A12,
sign-posted East Bergholt/Flatford) for a 700 meter walk. (Pay
parking available at Flatford) Watch out for the hordes of tourists
who come to enjoy Constable Country, and beware the nettles. You're
looking for a 1.9L 'Lock 'n Lock' container in a camouflage
cover.
