2/7 (Mynydd St John/Bryn Glas/Carreg Y Big/Mynydd Coch East Top/Moel Llygoed(Mynydd Coch West Top)/Drum Ddu/Foel Lluestbadlon)Fergalh23/02/2018
Bryn Glas, Carreg y Big, Moel Llygoed and Mynydd Coch East Top from cattle grid at SH91690 22879 following fences. The fence to Mynydd Coch East Top is as the OS map and is not the one just before (north) Carreg y Big. Fairly slow going and pathless in parts. 3h45, 6.89m.clivevilla06/09/2017
Parked at the cattle grid at SH91690 22879 and then followed the fence,crossing it to reach Bryn Glas and then more following the fence to reach a cross fence on the left after the obvious cairn on the sharp pointed top. Turned left and followed fence to trig on Mynydd Coch ET. Return back to main fence and then Moel Llygoed. Return was back to Bryn Glas missing out Mynydd Coch. Didn't cross the fence to the top. Back to car. Followed fence all the way so it would be easy in bad weather. Ground wet and very wet in places. Traversed on the fence at one point to avoid the bog.MikeM17/06/2017
Up grass path by Pen-y-gelli to elbow then followed fence line to elbow then broad ridge to Moel Llygoed. Followed ridge then took fence line out and back to Mynydd Coch East Top (real baggers hill) before going on to Bryn Glas, Returned by fence again then out to Foel y Bryn and an excellent track down to the road.SS22/04/2017
Parked by cattle grid at 917229 Followed faint (sometimes non-existent) path/ATV track along fence line to Moel Llygoed, bagging Bryn Glas & Carreg y Big along the way On way back followed fence line out to Mynydd Coch East Top; occasional ATV track, but generally pathless. (S)gerrybowes07/02/2017
From cattle grid to the North. As bad as the col looks its only really bad for a 6ft section. Climb is easy enough to the 535m spot. From there it does get a fair bit squelchier, a couple of sections with deep groughs. Summit area quite interesting- what looked to my eye the highest spot wasnt that marked by the 558m. Theres another rockier spot too which looked higher.this too not the 558m grid ref. Theres a small quartz rock at the actual top..I'm not convinced its the highest spot though.. see what you think.stig_nest12/09/2016
Parked cattle grid to north. Bryn Mawr, Mynydd Goch (direct route bit of a slog but still think probably beats long ridge route) Moel Llygoed, Carreg y Big, Bryn Glas.ijpowell14/07/2015
3416 7548 3411 Parked at cattle grid 9169 2287. Followed fence pretty much all the way to 7548 - like in pre GPS days! Small path by the side of the fence most of the time - some bog and bits of heather but not too bad. From 7548 aimed for a 3411 and found a fence - would be tricky to find in poor visibility. Then same again - path by side of fence. Returning from 3411 was tempted for a shorter line back as the ground didn't look too bad. Mistake. Recommend retracing your steps.destaylor16/05/2014
Parked at 974214 before completing a circular walk of Bryn Mawr, Bryn Glas, Carreg y Big, Moel Llygoed, Mynydd Coch East Top and Mynydd St John. The ground was a little damp in places but access was straightforward. Descending due north from the last summit I came across a gate into the forest that wasn't marked on the map.JohnStoneham10/11/2013
Start ~ 913233. Done on a traverse between Bwlch y groes and the A458 at Nant-y-dugoed.steve hudson14/04/2010
