2/4 (Mynydd Maes-Glas(Mynydd Clywedog/Tir Rhiwiog/Cefn Brith Uchaf/Ffrid Ddu)Fergalh21/01/2018
Parked on tiniest bit of verge on minor road near Nant-yr-onog. Up track then north to Y Gribin. Good route. Long route NE then SE on mainly pathless rough moor to Foel Lluestbadion & Drum Ddu then SW to pick up track to Tir Rhiwiog. Cefn Brith Uchaf then more rough moor to Mynydd Maes-glas before returning north to West bound track back to start. Tough walking when not on tracks.ijpowell12/05/2017
Tir Rhiwiog, Drum Ddu, Foel Lluestbadlon, Cefn Brith Uchaf and Mynydd Maes-Glas from layby at 936139. Frisky cows with young calves on the first part of the track up and mostly pathless after Tir Rhiwiog but a glorious sunny day.clivevilla10/05/2017
Parked in layby on A458 at 936139 Down road to Dol-y-maen & then up forest road to summit knoll Continued to Mynydd Maes-glas. (S)gerrybowes11/02/2017
Parked in layby up from Dol-y-maen farm and walked down road to take track all the way to the summit of Tir Rhiwiog. From there track down through forest then over tough terrain to a rather lonely gate into the felled forestry area. Fairly straightforward hopping past small pond to summit of Mynydd Maes-glas after passing track. Then headed straight east to regain the track - detour to head of boggy area then clamber through heather and tussocks for easy descent on track.SS16/04/2016
Mynydd Maes-glas and Tir Rhiwiog from A458 layby, in fresh snow.rhalstead21/11/2015
Parked as others - excellent track all the way.destaylor05/03/2015
Parked in the layby on A458. Took track up from main road at approx 943136 making a circular trip of Tir Rhiwiog, Drum Ddu, Foel Lluestbadlon, Cefn Brith Uchaf and Mynydd Maes-glas. Only attempted because the poor conditions prevented me from heading up Aran Fawddwy.JohnStoneham11/11/2013
from Llanymawddwy via Cefn Brith Uchaf. then on to Drum Ddu. if you ever need proof that doing lists where height is the criteria is daft then this is a prime example. you see nowt - but other two mentioned tops are well worthy for the view.stig_nest10/08/2013
Started from SH92619 13651 followed stream to forest edge and them track goes very near summit. Then off to be the first here to get Drum Ddu which turned out to be more interesting than this one.Martin R02/01/2013
With MP and AJ. Parked in lay-by nr Dol-y-Maen Farm on A458 and took good forest track all the way to summit.Man of Kernow112/05/2012
Start ~ 913233. Done on a traverse between Bwlch y groes and the A458 at Nant-y-dugoed. Conifer forest, at last relief from heather and bog!steve hudson14/04/2010
