With so much to see in this area, I missed this the first time around. My second visit this year was with the owners of the land and with their guidance I was led to this site. As Lubin says it can be found by heading north from Harford gate (Not a place to leave valubles in your car) and following the highest edge of the field walls. A track runs to a gate in the field system and then on wards towards Piles Wood. The cist lies on the hillside above the track just before the gate.
No sign of the capstone unless it is the stone a little further up the hillside.
