Taking the minor road east out of Wotton-Under-Edge you soon come to this Long Barrow (near the point where the road forks) There is room to park on the verge at this point.
I walked along the rough track to the north of the Long Barrow and from here it was a case of carefully hopping over the electric fence and a short but muddy walk.
The Long Barrow is about 25 metres across and 2 metres high – covered with brambles which prevented further investigation. A fairly ruined dry stone wall surrounds the Long Barrow.
Not much else to add other than that there are pretty good views.
