Couldn't believe that the summit is where it is. Hensbarrow Beacon syndrome. Did the vast spoil heap as it will be fair game for the Tamperers in the near future.Campbell Singer02/04/2018
walked from the south summit is in a wet field after recent rain near near the fence line. Had a good walk round as usual. The summit is dawarf by the waste.hodder26/01/2018
From the cattle grid. Had a look down the 'hole' to the N where the trig pillar once stood. Then popped up onto the spoil heap for a wander about the top. Sides are well grassed, but top is mainly not. Will it supercede Twn y Waun on HB at some point I wonder?jonglew25/11/2016
From east, parked in Layby. Across pasture. As other slag heaps are now included, this one should as well. Flat top.PeterD29/05/2016
Very artificial feel flat topAdrian06/03/2016
Climbed on a damp Sunday. A lovely view of the rubbish tip from the top but couldn't see much due to think fog. We parked on the main road. Not a bad footpath for most of the way.Jemma Singer31/01/2016
From Dowlais, right of way across A4060 (fortunately not too busy today!) and up to summit, then climbed spoil heap to be sure.Tony J10/05/2015
