Third top of three following Nuttalls twelve mile route from Aberllefenni. Route took in Waun-oer, Cribin Fawr and Maesglase.WAYNE ROWLETT29/02/2020

From the east, parking on minor road NE of Tyn y Celyn, then marked path directly to summit. Local symbols show this as an access path but it passes directly between TC and its garden. A barking dog alerted a local resident who was pleasant enough and said it was up to me, but advised me to go another way as the way forward was very steep and not advised by national park. Any other route would have been much longer so I pointed out the access sign and continued. A grassy track led up to 400m but then became little more than an animal track, but the only seriously steep ground, near the top, was bypassed.Topographer5727/08/2019

From Craig Portas, fine grassy hill, rain had stopped. A long day of following fence lines! Decided to descend via the waterfall.DanMaisieBex03/08/2019

This was our second attempt at this summit. Last year we followed the Nuttalls Walk, nice and easy up and through a shady forest. Then we emerged into the hot sun. Water supplies got low by the second summit and I became light headed ... dehydration, so we headed downhill. So this time where to park for a shorter walk. Decided on a lay-by on the A470, Not show on OS maps, but 2km NW from Dinas Mawddwy . Lay by seemed part of old road, under trees and very little used. OS 849 164. Track directly from lay by. But little used with fallen trees and the map was cluttered and hard to follow. Didnt seem to be a good starting point. Eventually we were heading SW up the valley and followed the path. In hind shift it might have been better to continue west to the fence and walk along that. Eventually we got to the summit - Craig Rhiw - Erch. Then back to Maen Du, over the stile and follow a twisty path steeply down. (OS maps phone app very useful confirming we were going in the rMalcvolm01/06/2019

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

P on handy grass verge at approx 830152. Good track to start - main height gain on very overgrown path - then ok incipient path in moorland. Visited Maesglase first, then Maen Du - good views down to A470.ger26/09/2018
Parked at Bwlch Oerddrws - Cloddfa Gwanas - Waen-oer then followed the grassy ridge fences to Maesglase (a grassy giant). Impressive and quiet. Returned retracing our steps. Coffee and bara-brith at Cross Foxes as a treat at the end.briandavies25/09/2018

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
