Parking at G 88002 36470 A I was confused to see such a sign as OS16 2nd Edition shows that this is part of O Donnell's Rock walk. Unfortunately this walk, although identified on the map, has little physical sign in reality. As luck would have it a local farmer explained that the sign was from a bygone landowner and the present landowners have no problem with walkers (no mention of horses)
Accessing the summit is by this track to top and through some turf cutting areas, although on a flattish area a higher mound is evident which I took as the summit. As this area is popular with paragliders who normally drive to the top from the South side, take a tar and gravel track past masts and park at a forest entrance ( G 87918 34895 B); from here it is a relatively short hop to the summit with little ascent.
