Visited 4.4.10.
Just to add to Elderford’s directions:
As you drive up the lane towards the farm house (on your right), there is a gate about 50 metres before the gate which gives you access to the field via a public right of way. The barrow is only about 20 metres from this first gate – directly in front of you. If you don’t want to trespass / ask permission, the barrow is easily seen from this gate. As an aside I noticed lots of mistletoe growing from the hawthorn trees – must come back at Christmas!
