What Travellers Say
Reviews Summary
Visitors praise the spectacular vistas and peaceful atmosphere of Craig Cerrig-Gleisiad and Fan Frynych, with many enjoying the circular walk and the chance to see unique flora and fauna. Some note the steepness of certain sections, advising preparedness for varied weather conditions.
"The circular route from the YHA hostel is fairly easy but (in the right weather!) offers spectacular vistas, over Brecon, across to Pen-y-Fan and southwest to the Black Mountain area. Going clockwise on the route means the steepest portions are tackled first (and going uphill) which helps if you are carrying a heavy 2-year old.... The T4 bus from Cardiff or Brecon (and points onward) makes this an easy day trip from either place - the stops are just 50m north of the car park."
Ian Richardson
"Lovely circular walk, parked in the lay-by, quite steep at first, we walked clockwise direction. Stunning views, peaceful, minimal people. Seen the gorgeous ponies, passed the trig, first time here, will definitely do it again.."
Clare Sheppard Gale
"There are several points along the Beacons where you can get really excellent views of the ridge line. Fan Frynych within Graig Cerrig Gleisiad is just one such viewpoint.
Walk in from the main road to the east, up a lovely silver birch wood, with the glorious cwm in front of you. I like to swing right, heading north around Twyn Dyllaun-ddu before dropping down onto the old Roman Road. Fine views all the way west to the Carmarthen Fan.
A couple of kilometres west on the flat, before you pull steeply up to a whaleback ridge, and an open flattish walk to the dragon trig point.
It’s here, and on the descent options that the views really become rewarding, with the twin summit plateaux of Corn Du and Pen y Fan directly in front of you.
Skirting the cwm to the south is spectacular, but the drop back to wood is very steep, and you may want to trade off by dropping over the cliff edge on the more direct path."
