This is a hump; the official summit coordinates (ST 17684 90939) have become irrelevant. | Matt | 02/05/2023 |
From road head along rocky track, some flytipping. Across mine spoil to a flat summit. Area slowly being colonised by trees. Great views. | cjo | 29/06/2022 |
Cracking run from Bedwas … ran around top for a bit to make sure … not the prettiest top and now demoted | milejunkie | 08/02/2022 |
On a sunny, solo walk from the Sirhowy valley below Wyllie, after visiting the many Bronze Age cairns at Mynydd Bach and Twyn Cae-Hugh. From the largest cairn, the landscape rises in a brown wilderness of shattered earth, up the unnatural slopes of the tip. Worth heading up to the highest part of the artificial area for the views, but not terrain to savour. From here I headed SE to the fine cairns at Twyn yr Oerfel, then on to Pen-rhiw Tip and Mynydd Machen. | thesweetcheat | 30/01/2022 |

Definitely a bing with a smoothed bulldozed mine -spoil surface with ditches, possibly being prepared for tree planting. Dark and rainy but nice lights in valley. After Dimlaith via Rhymney valley Ridgeway walk. | Denise | 28/11/2021 |
An interesting world of rolled grey mud criss-crossed with drainage ditches. In darkness and dreek all a little surreal. From Mynydd Dimlaith, returning via the Mountain road then looping lane with good views of the lights of Caerphilly. | RichardM | 28/11/2021 |
Owner of Pen-y-Waun OK with parking at end of lane at ST 16828 89994 - Up slabby track to junction at 171907 & then E. on good track to wide gateway at 174906 - Through gateway & up over 2 tracks of colliery spoil to the higher & much wider roadway - SE along roadway to 177905 & then up to the high point of the spoil heap (375m) which is being colonised by a mixture of grass, heather, gorse & spruce. Natural high point (355m) located somewhere to E, lies beneath metres of spoil. (S) | gerrybowes | 07/10/2021 |

Bedwas to Risca. Very minimal vegetation amid the bare soil of the moulded summit cone. | Smudge | 14/12/2019 |

07.30 the hump which is a moonscape mess & aspiring Marilyn since there is maturing pune forest up to above 370metres and there are full contour lines on the 1:25k map on this former coal slag heap. | vegibagger | 22/07/2019 |

1/2 Parked just after cattle grid on road to west, pretty direct walk up through mud, fly tipping, and bikers. Not the most pleasant | penbet | 25/06/2019 |

Quiet midweek morning. Relatively easy to find the way to the top. Pleasant views, but perhaps won't live too long in the memory :) | kasharic | 20/07/2018 |
From Bedwas, up Church Street then Mountain Road, then across sheep field to the fenceline, onto the spoil tip, up via the track on the western face, and on to the highest point, at the eastern end. | Mariana Trench | 23/05/2018 |

TGIF because I guess at weekends the rubbish dumpers and the trailbikers are out in force. Drove to near masts to N, unmade road beyond too rough for my 2WD so ran from there. Enjoyed my 35 minson this hill, in the sunshine, but that was well enough. Fridge still there. | pwheeler | 20/04/2018 |

Up from Bedwas. Grim - weather & hill. | ngthack | 01/10/2017 |
Must've missed Nigel by just a few hours, though I was there at 3:30AM and it was probably even grimmer then. Quite an alien experience in the dark and mist actually. | Alex C | 01/10/2017 |

Parked just beyond cattle grid. Horrible area, full of fly-tipped rubbish. | liljonb | 22/01/2017 |
