With E. Parked on forestry road at foot of hill opposite minor road junction. Walked up road (surprisingly busy) than onto grass and flat summit. Went to both SN6647009482 and SN6650109537 to ensure highest points covered. Also had a wander around the nearby ancient earthworks marked as Penlle'r Castell on OS map which are slightly higher but man made. Good views on a sunny afternoon. Area surrounded by wind turbines.Beeliner16/07/2019

I thought this was going to be exciting when I saw the signpost to Mynydd y Betws on the A474. Must be a top tourist attraction that it deserves a signpost? Sadly, not.Gill22/02/2018

With Chrismagirob13/10/2015
Unashamedly parked at the road highpoint and had a little wander around the grassy, tussocky top which must have looked odd to the passers by... Didn't bother with castle as was pressed for time. Not the best.bowlesy10/10/2015
Appears to be a tuft of grass very close to the road where we parked. With GB.bolton28/07/2015
