Solo. From lay-by on A470 near Dinas Mawddy ( approx GR 857149). Steeply up through forest then long contour to Bwlch Siglan. Up path running parallel to edge of forest then around escarpment to Maen Du. On to flat summit of Maesglas. Descended following fence SE then rejoined outward route. Great weather. Poor paths and slow walking . Took longer than expected.mike.hoult22/10/2018

The farmer at Ty'n y braich kindly let me park at the farm so it was an easy walk up the pleasant valley to bwlch siglen. Going round to the summit the ground was quite boggy and the path surprisingly close to the edge of the cliffDavid Bell01/05/2017

Heavy morning rain slow to clear replaced by gradually clearing skies with good visibility. Strong wind became stronger almost blowing me off my feet on many occasions. Parked in car park near 363m spot height on A470. Cribin Fawr->Waun-oer->Craig Portas->Craig Portas East Top->Maesglase->Maesglase (old GR) - Maen Du. Only 7.83 miles but comparatively a lot of ascent at 964m. No wonder felt tired on final walk back to van along A470 from Penantigi Isaf. Better to park near milepost to reduce final walk back to van.SteveSmith09/03/2016
With Jenx from A470. Straight yp from farm to North. Steep but direct.nordicstar30/12/2015
Steep ascent but very direct. Very quick down.jenx30/12/2015
Continuation of walk from Foel Dinas. Followed overgrown path through bracken down to Bwlch Siglen, then steeply up onto plateau. Then traversed above the cliffs and broad south-east ridge to the summit. To descend, continued to old summit, then very steeply down to Moel Cwm yr Eglwys 509m, then steeply down through bracken to A470, following this on grass verge back to Dinas Mawddwy. Solo walk.marktrengove29/09/2015
With Penda, from car park on A470. CF to W to M and back. Long flog over boggy ground on way to M. 1230-1715. Trip enlivened by lots of Red Kites. Only saw one other person in distance.beorwulf19/09/2015
Nice walk up to Bwlch Siglen in torrential rain, with a bit of dodging around unmarked footpaths. Fabulous views of the valley while walking round Craig Maesglase, until close to the top. Along the ridge to Cribin Fawr, and warm sunshine by Craig Portas. Nice peat hags and mossy tussocks on C. Fawr. Down the track towards Penantig Uchaf, which soon gets lost in bracken. Back via Pont Buarth-glas (unmarked footpaths theme continues) and the track on the N side of the A470.Gill22/08/2015
