Take the A30 east out of Stockbridge until you come to the junction with the A272.
Take the turning north (on the left) and the Barrow should be in the field on your left right next to the road.
The only problem is I couldn’t see any trace of the Barrow.
Perhaps it has been ploughed out since E.H. last visited?
‘Long Barrow surviving as a low earthwork, situated just below the crest of a gentle SE facing slope. It survives to a length of 33m abd varies in width between 15m at the east end and 10m at the west end, standing to a maximum height of 1m. Flanking quarry ditches run parallel to the north and south sides of the mound, separated from it by narrow berms 1m wide’.
