With: solo; Nuttalls walk 7.5. Good dry day with light wind and high cloud | Ian Baines | 09/10/2022 |
Updated Nuttall 7.5 from Bwlch yr Hwch: Foel Goch, Trum y Gwragedd (Trum y Gwrgedd), Foel y Geifr, Pen y Cerrig Duon, Pen y Boncyn Trefeilw, Stac Rhos, Cefn Gwyntog North Top, Cefn Gwyntog, Cefn Gwyntog Far North Top, Foel Cedig and Y Groes Fagl. Haxy, dull day, so there weren't even good views to distract from the relentless trudge through heather. | Lazylizzie | 03/09/2022 |

4th Mountain today. 
Not the best walk down from Foel Y Geifr, struggled to find a path through the deep heather, headed for the Hirnant col where you can see a track going up the hill. From here follow the road all the way to the next top. | Buckleymon | 15/08/2022 |
Risked taking my car up the open track. A bit rough in places but driveable with care... From the track | vegibagger | 07/06/2022 |

From road/track junction at pass. West to Foel y Geifr then north over 612m top and on to Foel Goch and return to pass. Then east along good track to Peny Boncyn Treifeilw use fence to locate) and on to Foel Cedig which took a little bit of searching to find the small cairn. | dickscroop | 03/11/2021 |
