Parking at pt486, SJ017305. Blind FP to info sign, then partial boardwalk ESE to cairn at circa SJ029302. About 300m past this, at a cleft with a white rock, an erratic faint ATV tk goes off SE to two fenced squares. NB tricky to find start of ATV tk for the returnIsbjorn24/06/2024

Combined Nuttall walks 7.3 and 7.4: Parked at Milltir Garreg walked down the road 200 yards and picked up footpath most of the way, then final trudge through heather to summit. Retraced footsteps, the up the road to bag Post Gwyn. Followed boardwalks and hard to find quad bike track to Bryn Gwyn then heather slog to summit of Post Gym. Unseasonably warm November day. Finished just before dark.Lazylizzie13/11/2022

From pull in on B4391 Montgomeryshire, Denbigh border (SJ017305) on way to Post Gwyn. A board walk path heading for the main Berwyn ridge can be used at first before having to cut right over tussock and heather. A nothing of a top but Post Gwyn summit good.Neil Midgley15/09/2019

Parked high on road then track of sorts to duck-boarding which you should leave near obvious cairn to tackle the horrid heather to Bryn Gwyn a P12.7 before the two top of Post Gwyn.Dugswell223/11/2018
3 degrees at spot 464, calm, thick mist, some snow on ground, with Dugswell2. Cursed through the heather, spurred on only by the prize of collecting a deleted Nuttall. On to Post Gwyn.Wycombe Wanderer23/11/2018
Followed the Nuttall's route to Post Gwyn but turned up the hill too soon, seduced by a path which looked pretty good. Needless to say it disappeared eventually and it was all through heather and bilberry from then on. Fortunately not the worst by any means. Then did an out and back to Bryn Gwyn before taking a direct route to Glan-hafon which I thought a nicer hill. Returned to pick up the standard Nuttall's decent to the falls.Herbert Anchovy24/06/2018
From point 486m on road to WNW. Duck-boarding made life easier on first section, but the ATV track SE didn't look as though it had seen any ATV activity for years. Was also very wet and soggy, think yesterday's deluge that had flooded Birmingham must have tracked NW. Continued to Post Gwyn.Aye Jimmy28/05/2018

CHAOS Club walk, Tony, Steve and Brian, from the waterfall, on to Post Gwyn. Lovely sunny day.Lou20/06/2014
Start at quarry in mist. 017305. Path follows boardwalk making progress much easier up to the pond at 034302. Then kept to buggy tracks through deep heather, bog and tussock grass. Passed over Bryn Gwyn on way to and from the top of Post Gwyn. View from top clear and we could see Tryfan to the north. Returned by same route as rain set in for the afternoon.axe.stephen25/05/2014
