Access Information

Car parking is available at SN 81996 27149. From here take the track leading south to SN 82216 26547. Cross the wall via a stile and head across open moorland to the row. It is worth having a look at the stone circles a short distance to the south east of the row. A stream needs to be forded and wellingtons may be the best footwear for this one.
