2/3 - started 916957 - fine weather - seemed to take a long time to reach - as the made track heads L downhill, follow the earth track steeply uphill - branch right and eventually leads over highest pointwychwood19/04/2019
Came across from Mynydd Blaengwynfi. At N51 40.335 W3 36.081 I forked right up steep track, then right at N51 40.120 W3 36.543 up to high point. To get down I returned to N51 40.335 W3 36.081 then west along main track and lesser track to the mast at N51 39.702   W3 36.746 but heeded earlier advice and took track west here rather than east past mast. The west track weaved its way down the hillside before ending up in the west end of the village.Father Ted10/04/2019
From Mynydd Blaengwynfi. Along good forest tracks past wind turbines, up lesser tracks to HP. Wish I had read other logs on here more thoroughly as the path down from the mast petered out very quickly and left me thrashing around in high bracken and brambles.PeterD09/09/2018
Roadside parking near top of Upton Street in Blaengwynfi at 892965 - Up Mynydd Blaengwynfi & then continued NNE on old forest track which joins up with an excellent track that can be followed around the head of Cwm Gwynfi to fork at 894984 - Branched right & along overgrown track to fork at 888978 - Again, branched right & up past metal water tank to the summit which lies alongside the high point of the track. Descended back to main track at 894984 & followed this back to village. (S)gerrybowes02/02/2018
Mynydd Ynyscorrwg and Mynydd Blaengwynfi more or less as marktrengrove. 6.72 miles. Blaengwynfi is a depressing little town.clivevilla25/08/2017
Parked at the end of the lane at SS 88554 96875 in Blaengwynfi. Took the zig-zag track up round the west side of Cwm Gwynfi. Then a steep thrash up the side of the forest to a higher overgrown track, following it west, then on a lesser path north-west past a metal reservoir up to the summit area. Left the path for a painful thrash in the thick forest west of the path to be sure. Don't bother, as path seemed as high! Onwards to Mynydd Blaengwynfi. Solo.Man of Kernow117/06/2017
From Caroline Terrace, Abergwynfi, on 6 mile circular walk to take in Mynydd Blaengwynfi first. HP on a track in conifer plantation - went into forest but ground seemed lower on both sides. Long section of wind farm access roads between the 2 hills. Bit of a mare coming off the hill from SS89019707, missed the track if it exists; not to be repeated!jonglew01/02/2017
Start ~ 888967, Blaengwynfi village. Up Upton St. to forest tracks and on to Mynydd Blaengwynfi summit. Continued North then west on new tracks to Mynydd Ynyscorrwg. The old tracks here are getting very over grown. Descended to phone mast then the long way to village. With wombourne.steve hudson07/09/2015
From GR 888967. Walked over Mynydd Blaengwynfi then continued to Mynydd Ynyscorrwg. With SH.wombourne07/09/2015
An out and back from Blaengwynfi. Forest tracks all the way. OK for half a day.MikeM13/08/2015
Parked at forestry gate (SS917956)and followed rolling forestry tracks all the way. Past early construction stage for new wind turbines. At 502m spot height there is no view. The walk was quiet, not the shortest route but I was in no rush.Dusty07/05/2015
From Blaengwynfi up path to forest track (note the upper one isnít obvious from top of path). Then on over tracks and paths to trig point (keep your eyes peeled Ė screened by trees). Round forestry tracks past a wind turbine base and on up past old water tank to summit. Made mistake of trying to drop from mast to village on old track (donít). Came down to west on tracks in the end.SS15/03/2015
2/5 Long tough hike up from Glencorrwg...track not clear but when in forest easy to foolow tracks to top which is beside metal water tank in the treesFergalh08/02/2015
Along with Werfa and Myn' Blaengwynfi.dicky06/08/2013
