I have added Glenterrow Cairn, an almost destroyed cairn 50 metres SE of Glentirrow/Glenterrow Stone circle to TMA. All signs for the stone circle have been removed so after some trial and mostly error I would recommend the following route for visiting Glentirrow/Glenterrow Stone circle.
Directions: Take the New Luce turn off the A75 at the E end of Castle Kennedy village. After 3.5 miles there is a gateway on the L at NX 1478 6240. I would be cautious if there are beef cattle in the field as they can be dangerous. There is a farm track leading N at first then bearing NW into a gateway at a boggy corner. Go through the gate and head SW up the field parallel to the fence for 350 yards. Glenterrow Cairn is in the SW corner of the field. Glentirrow/Glenterrow Stone circle lies 50 metres NW in rough moorland and can be seen from the field corner.
