From Llangynog after Glan-hafron, following same route as. Moorponder. Surprisingly good path down through bracken to Nant Sebon.PeterD20/05/2024
From Llangynog (free parking) E along minor road then RoW to 072278. Ascent on easy grass to 608m top. Back to col then beside the fence NW over the shoulder of Y Clogydd. Over easy grass along the line of the RoW SW to Bedd Crynddyn. Followed fence around danger area and up easy grass to Craig Rhiwarth. Returned NE at first then followed good path down Nant Sebon to reach the starting tracks.Moorponder21/06/2023
Parked in Llangynog for a 4 Dewey walk. Roughly followed Wayne's good route on RoW up alongside Nant Sebon to the sheepfolds, then using the small tracks on west slope of Moel Crynddyn and onto Craig Rhiwarth. Then along the Y Clogydd ridge to Glan-hafon, high point + trig. Returned down the bridleway to Llangynog for lunch. In the afternoon headed up the RoW alongside the now closed Revolution Bike Park, then followed the forest road to the top of Carnedd Das Eithin. Not wanting to go all the way back to the cross roads, I risked the narrow strip of dense woodland. So went to the corner at SJ 0474 3204, where there is even a gateway into the what is marked as a ride. In reality it is an avenue of young deciduous trees, with sufficient space to squeeze through. My gamble paid off, and I was on my way up to Ffordd Gefn without too much difficulty. Access via ride at bend in fence. A windy day with heavy showers but beautiful rainbows as well. 22km with 1600m ascent taking me silveracorn_alan10/04/2023

From Llangynog. Craig Rhiwarth and Glan-hafon.Gwastadros19/11/2021
Parked in Llangynog for a Seven mile walk to Craig Rhiwarth and onto Glan - Hafon, via Nant Sebon and following a track to the end on the north side of Moel Crynddyn, then walking on the west side of this hill to reach the first top. After retracing my steps back to the 505 meter top I used the track around the head of the valley and struck across Y Clogydd to reach the col with a cross works of paths and finally up to the second top. Retraced my steps back to the col to follow the bridle way back to the minor road leading to Llangynog. Five hours.WAYNE ROWLETT15/08/2021

Parked in layby at SJ 04517/27476. Walked down road to start walk up forest track. No go large ornate gate and fence across. Walked down to white cottage and took track opposite.Next followed 1000 feet of quite steep asent. Good path following a fence for much of the way through ferns then bilberry and some gorse. No heather. Top part: the bilberry has been burnt providing good walking. Top not marked but 25m south of cairn. Top covered in stone circles and a defence wall. Returned the same way.MikeM07/06/2021

Parked in a small layby on west side of road just north of the small river at Pencraig. Vast amounts of money have been spent on gated property which was the access to the forest. A path opposite the White cottage south of the river gives a decent track/path to directly north of the summit and then a short climb to the cairn. With Degsy. 80 minute return in good conditions.bolton29/04/2021
An imaginative ascent from the car park in the village. This aspect of the hill looks very intimidating and imposing but it is possible to find a route through the slate rubble and crags. Look for the ramp from below and once you reach its zenith its possible to negotiate a route through the spoil heaps and a short scramble through the crags ensures a safe passage. Luckily for me, the weather was good the lack of recent rain meant the rock was dry and good visibility allowed me to plan ahead. I wouldn't want to do this route in poor weather though! Great summit and evidence of old fortifications.thenomad27/04/2021
Up from layby in Pencraig: track past old buildings into field and up.PGCE03/02/2021
From Llangynog for a round of Ffordd Gefn, Carnedd Das Eithin, Craig Rhiwarth and Glan-hafon.rhalstead12/09/2020
Large non slate (?porphery) cairn on grassy sheep pasture with extensive views. Excellent direct ascent from village carpark via slate mines. Blustery cool day. Repeat ascent.Denise 05/08/2020
A great route from Llangynog up through the old slate workings. Small cairn at high point.RichardM05/08/2020
With Judy: Went up ridge and descended down river vally and track. Plenty of minor sheep tracks but with crutches found the patches of heather, gorse, moss covered stone, and deep soft tussocks quite hard.GordonAdshead21/03/2020
From Pistyll Rhaedr, over Y Clogydd to Craig Rhiwarth (tip: on reaching track dont use it but keep to left of fence through fields to avoid gates, fences and rough grass to criss) to Glan-Hafon and return.ijpowell12/07/2019

Parked as destaylor at SJ 0457.2741. F/p starts just down road, up this short way towards house then broad shoulder on R direct to top. Hard work in the heat.Aye Jimmy28/05/2018
Quick bag up and down from Pencraig layby, had to bag this one because it looks so good from the road. Steep pull from road on barely existent trails to summit cairn in overcast conditions. Earlier that day did a 9 mile walk taking in Pen Coed-Y-Bedo, Bryn Bras, Pen Y Cerrig-Serth, Orddu, Foel Goch, Garnedd Fawr, Pen Y Bwlch Gwyn and Moel Emoel.DanTrig19/08/2017

From Llangynog (with Glan-hafon). Climbed the very steep slopes to E, threading way through crags. Visited both potential tops.RobertP15/05/2016
Direct ascent to look at the mine relics. Didnt find a great deal. Certainly left some sweat behind though. Boy is it steep. Mix of slate and scree and heather further up. A fine spot though. Descent to east. Cairn at top and a very remote feel too.stig_nest13/05/2016
As Des Taylor although I took the path into the forest by mistake. The correct path leaves the road just south of the forest up a drive towards some houses then veers off half right before reaching those houses.clivevilla23/12/2015
From Llangynog up road to Pencraig then through open field to col north of Craig Rhiwarth. Up and down then followed track onto ridge and along to Post Gwyn. Returned and ascended Glan Hafon before taking row back via Cwn Glan-Hafon.SS11/04/2015
From Llangynog after a visit to Pistyll Rhaeadr.mad max13/06/2014
Parked easily 04572741. Took track not shown on 1:50. Then path then wheel ruts all pretty much in a straight line to the summit. Easy to get to Fort from summit.destaylor15/05/2014
Climbed from Llangynog on a beautiful June evening. took lane below hill east, then track into cwm between Craig Rhiwarth and Y Garn (incorrectly called Glan-hafon = "Riverside") on OS maps. Followed sheep-trods up by stream west between NE spur and Moel Crynddyn, and then from bwlch to summit. Descended west into Cwm Orog to B4391, and thence back to Llangynog. A fine and interesting hill, made, unusually for the area, of volcanic rock.Man of Kernow110/06/2013
