Walked over from Storey Arms to visit Nuttalls at E end of main Beacons then dropped from Allt Lwyd, contouring round to Allt Forgan, flat topped no distinct summit. Dropped SSW to road at river crossing--probably would be overgrown later in yearrichardrosser06/05/2019
From the top car park and up the path to Craig y Fan Ddu. Plenty of people on the lower slopes but above 600 metres they melted away. There were a few snow patches above 600 metres. I carried on to the summit of Waun Rydd which carried a dusting of snow and some impressive icicles coming off the peat hags. Visited all 3 high points before heading down to Bryn. This was a great viewpoint but as the weather was closing in I back tracked to the summit of Waun Rydd. I headed south through a blizzard to Cwar y Gigfran. The wind was ferocious and I was pleased to get off the plateau on the path to Allt Forgan. The summit was unmarked but the high point was fairly obvious as at this height I was below the cloud base and there was even some watery sunshine. It was then a bit of a slog getting back to the car as I couldn’t cross the river until I reached the wooden footbridge which then meant a reascent through the woods. Time taken 4 hours for 10.5 miles.isabelle17/03/2019

After walking round hills near Aberdare rain set in so headed up here to try and find dryer conditions. It was even wetter!Dusty22/04/2018
Parked in wide entrance at start of forest track at 066170 - Up track to junction at 0735 1785 - Turned left & up track to gate at top of forest - Continued WNW along track to an overgrown low wall & then a short ascent to the unmarked featureless summit. Returned same way, a round trip of about 3½ miles. (S)gerrybowes20/02/2018
Car at the foot of the BW near Abercynafon. Via BW, forestry tracks to the edge of the forest and then an easy plod over moor to the top.Moorponder09/10/2017
Parked at bottom of forest access road (SO065170) and followed this until farm access track (SO073178) which lead to summit.Ramblingpaul26/09/2017

Ticked off coming down off Waun Rydd. The way off the SW is not particularly pleasant. Nor is the walk back up to the car park!huwthomas22/01/2017
On the return from Fan Y Big, bagged after the Cwar y Gigfran cliffs & the Memorial to the Wellington crew.DanMaisieBex28/10/2016
From the lower car park, straight up steeply wooded slope, track eventually found, easy from there, but still steep. Made a circular walk of it, penetrating forest to E at SO 07115 17693 and folowed forestry vehicle tracks back to the road at SO 06657 17005.jonglew03/10/2016
Started in top car park above the Talybont reservoir. Walked out on main path taking a left turn after a few hundred metres. Continued on path to edge of forest and turned right and downhill to stream. Forded stream and then up the other side to where the incline is less steep. Turned E of S to continued to top of Allt Forgan. Crossed two fences on way. Dropped down to lower car park and then on to Beacons Way. Note Were stream cross Beacons Way at edge of forest and felled area there appears to have been a collapse of the track. Turned right and climbed up to Taff Trail through the felled area. Turned left on Taff Trail and followed to where path up from Abercynafon Farm comes in on left. Turned right and followed path to where several paths join near Pen Rhiw-calch. Nice seat for lunch there. Turned right and followed right hand path to Pen Bwlch Glasgwm. Continued on track to where another track on right leaves main track at right angle. Followed this and over moor to top of BryniauMikeM12/05/2016

6/8 Long but enjoyable day in the Brecons Bwlch y Ddwyallt (Gwaun Cerrig Llwydian)/Gwaun Cerrig LLwydian (Craig Cwareli)/Bryn/Waun Rydd/Alt Lwyd/Allt Forgon/Pan Y Creigiau/Bryniau GleisionFergalh27/06/2015
Pant y Creigiau and Bryniau Gleision from the upper car park then back to car park and Allt Forgan. The track from the car park towards Allt Forgan ends abruptly with only a faint path to continue on. This gets very boggy before disappearing altogether. On the way back there is an obvious track/path through the forest but it is difficult to find on the way out (a small path leading off the track to the left).clivevilla25/06/2015
From Blaen-y-glyn Lower Car Park near Talybont Reservoir (SO 06251 17046) - Allt Forgan. Followed forest track at SO 06662 17001 then joined minor track at SO 07352 17843 to gate at top of track, from here a short distance to the summit. Descended via the same route.david23020125/05/2015
Took note from hodder and tried ‘path’ beyond road end at top car park. Managed to battle though to fence line. Then on to natural stepping stones about 400m upstream. Easy angles from there. On return avoided ‘path’ and instead found stile just to west leading to real path back to forestry road (it is obvious on your left after about 200m from car park taking firebreak).SS17/03/2015
Start ~ 062170, Carpark. Followed the track up to the waterfalls before crossing on a footbridge. Carried on up the valley for a while before turning directly for the summit. With Wombournesteve hudson30/10/2013
Start GR 062170 forestry car park. Followed track through forest until bridge allowed us to cross river. Continued up on path until below summit then headed steeply up grass/heather slope to top. Descended down E ridge then into forest. With SH.wombourne30/10/2013

Easy parking to SSW. Not much by way of paths but OK.destaylor11/04/2013
Up the stream and water falls before turning off and following the fence to the summit. Lots of areas could be the highest point.rhalstead06/04/2013
From CP at bottom of Blaen Y Glyn waterfalls, over newish wooden FB, then NE and E. No real paths up the west slope and rough scrub and residual snow made it difficult. Barbed fence at top and no stile? Returned by going north on clearer path, then west and down to the path running south alongside river and waterfalls.dicky16/01/2013
climbed this on return from walking horseshoe around craig fan ddu easy climb but had to negotiate 2 fencesrussf6913/05/2012
walked on the the main pathway through talybont forest from the direction of blaen-y-glyn. Their is a smaller path here straight out to allt forgan (not marked on the 1:50,000 map)hodder23/01/2009
Open summit without obvious high point easy access from Waun Rhydd but tougher going on lower slopes heading back to carRhayader_wander29/06/2007
Solo from car park- Forest hell, then set off climbing the wrong hill until I realised nothing fitted. Down to the Brecons for a few days to help supervise a Gold D of E group with Jenny L and Peter from Seaford.Chris Pearson19/04/2006
