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

Clearly lower than main Nuttal summit. 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

Walked here rom true summit of Maesglase.peter4lc03/07/2006
Visited the cairn. From here dropped off to the north. Took the ridge down to Penantigi Uchaf a farm now owned by an American. Unfortunately the right of way ends at his farm and he was not aware of this. Still he let us through to make the A470.garyhoney21/07/2002
Diary says 'Permission granted to start from Penantigi Uchaf'. Could have been ironic.Eddie12/11/2001

No record of first date; been here several times as it's on the (original) Meirionydd Round route although no-one's yet managed to include it. Lovely summit, wonderful steep climb from N.RHW01/01/1990
All summits visited today were well worthwhile, making a grand traverse: Bwlch Llyn Bach- Mynydd Ceiswyn- Waun-oer- Cribib Fawr- Craig Portas- Craig Rhiw-erch- Maesglase- Bwlch Siglen- Dinas Mawddwy. Being on this summit, I took the natural line down to Bwlch Siglen, along the top of the cliffs and above the waterfall, where there was no problem with the terrain; very impressive way down amongst attractive looking alternatives.
