From mapped roadside parking area to NNE (SH 8021 1702). Good track leads up to Cribin Fawr first, then a divert across to Waun-oer before getting back on track to Craig Portas, its E Top, Maesglase and then across to here. Took a steep descent NW down to Penantigi Uchaf to ascend Camlan as a final hill of the day. | jonglew | 16/10/2022 |

Brief visit to E summit after west HP for Barry's final Welsh Marilyn. Levelish grass before descent down NW ridge to road- nice grassy descent, with stream crossing over fallen tree. Repeat. | Denise | 16/10/2022 |
As Jonglew for Barry last welsh Marilyn. Party of 12. Started at carpark at head of pass finished by decending to east were a car was used to transport back to start. The descent down steep ridge has been used as an extreme downhill mountainbike route with big dropoffs jumps and high death factor at start. | cjo | 16/10/2022 |

Maesglase & Maen Du - Dyfi Hills. Parked on A470 large lay-by at SH 82643 16350 at Pont Buarth-Glas. SE over rickety fence onto hillside and followed the W side of the stream cutting through the LHS of Craig Buarth-Glas, extremely steep requiring lots of pulling on vegetation, collapsing ledges and loose rock, exciting. Up to fence and Moel cwm yr Eglwys then ridge and path to Maen Du and fence to Maesglase summit. Descended NW spur of Maen Du to around 450m then steeply down bracken and grass to cross Nant y Cae at 270m and easy pastures to gate onto A470 just W of lay-by. A really impressive mountain, tough from the north with sustained slopes of 45 degrees. | jacobrichmond | 22/11/2020 |

Nuttall Walk WN 10.3 West of Dinas Mawddwy from Aberllefenni. Mynydd Ceiswyn, Waun-oer, Cribin Fawr, Craig Portas and Maesglase. 20.4km with 1170m ascent in 7h15m. (S) | silveracorn_alan | 29/03/2016 |
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. | mntainman | 09/03/2016 |

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.
