From Rhyd Ddu CP (£6.00) - visited Y Aran first, then back to CP & on to Mynydd Mawr (via track through forest). Y Aran is an excellent hill with a really good mountain path from the bwlch.ger28/03/2019

From Rhudd Ddu. Mynydd Mawr, Moel Tryfan and Clogwyngareg. wet and very windy!!Alunrees3327/09/2017
Usual route from Rhyd-ddu but made the mistake of following the Nuttall route down. This was exceedingly rough going and we wasted ages trying to circumvent the crags at the bottom, eventually stumbling through the plantation to gain the lakeside track - horrible. Nice mountain otherwise with great views.milimana16/09/2017

Overcast, 9 degrees, cloud dropping to 2250'. Climbed NW from chapel to south. Steep, lots of gorse and electric fences but nice bit of ridge at top with close-up views of impressive south face. Trum y Ddysgl looks higher than it is and mighty impressive. Return same route. 2 hours.Wycombe Wanderer05/04/2017
