Alongside Sarn Helen, fir clad. Sarn Helen marked at intervals with low concrete pillars with very attractive bronzy plaques. Sadly, only one found with plaque intact, all others nickedrichardrosser05/02/2019
Christmas Eve mast run. Found trig point within treesphilwhit24/12/2018
From NE starting at Banwen. A labyrinth of biker trails eventually led to the summit path.Topographer5730/09/2018
From Banwen, up Row and forest tracks, then Sarn Helen. Trig hidden in trees. Also visited the Bing to the South which looked as if it may be higher, but wasn’t.PeterD10/06/2018
From Banwen to the north. Trig not that easy to spot to south of wall when it's very misty.Minto11/04/2018
Easy walk from Banwen, first on logging and windfarm roads and then on Sarn Helen, a right mess due to trail bikes. Trig is easy to find at the high point of the road; look for a small path where the wall has collapsed.Gill22/02/2018
From Banwen - surprisingly nice views N given the uninspiring start on forestry tracks!twg2730/11/2017
8/8M last for today good tracks from banwen.robertphillips10/11/2017
As with most other people, from Banwen. The mix of forestry tracks, windmill roads and unmarked RoWs was a little confusing at times, but you can't go much wrong if you just keep going up. With Keith and wee Ross.islamidget08/10/2017
With: hb; Parked in Banwen and followed byway on to Sarn Helen, then followed this all the way past new wind turbines to the Trigpoint. Lunch was disturbed by trail bikers. Returned by the same route.Ian Baines19/08/2017
Parked 856095. Followed the Roman Road and forestry tracks to summit paste wind turbines.Hippy7712/02/2017
As Ted, drove down from Shropshire full of a cold. Of course this meant the walk felt far tougher than it oughta. A couple of things struck me on this hill. One, Theres a far better view than expected. Two, Whoever owns the place is very liberal with their health and safety notices.. dont do this - watch out for that! Trig pillar has a lovely mossy wintercoat.stig_nest14/12/2016
As other have done I parked in Banwen and up the tracks from there. Was blessed with fine autumnal sunshine, light winds and no trucks, bikes or off roaders. In fact I didn't see anyone all afternoon. Cane down different route grabbing some geocaches on the way.Father Ted01/11/2016
From Banwen. Wonderful views north as you ascend. Waste tip to East of summit is higher, and has a bit more vista.huwthomas17/09/2016
#601 - From Banew along Sarn Helen with the Creaking Hiker. Nothing nice about it, blowing a gale, wet, no views and having to avoid the off-roaders wrecking the roman road!tim74709/07/2016

Followed Roman road from Banwen (birthplace of Saint Patrick). The atmosphere of the ancient road is rather spoiled by the recent windfarm access tracks, but nice view from the top.Cas-gwent15/03/2016
Followed the Roman Road out of Dyffen Cellwen to the top. The first half of this is currently a wind farm construction road and they were even busy on a Sunday morning. The trig pillar is getting engulfed by a tree.mindlessflogger13/03/2016
With Jenx from end of public road, start of forest access area at Banwen. Gloomy hill subject to much abuse of forest, opencasting, power lines, off roading and now wind turbines. Multitude of tracks not shown on OS, best take a GPS to be sure. Top is near trig, bulldozed spoil heaps are not marilyns and not worth the visit. Seems the wid turbiners have stopped the 4x4 antics, although not trail bikes.nordicstar20/02/2016
Pylons,forestry,motor racing, opencast mining, bulldozed tracks, mud, wind turbines, mist, gale force wind. Lovely.jenx20/02/2016
From the road end in Banwen. Followed forestry tracks then roman road to trig point. Also visited bulldozed ground which seemed higher. Returned via same route. Took around 1hr 30.bowlesy10/10/2015

With Trefor. Warm suny day. Forest tracks a bit confusing. Highest point is a spoil tip about 100m from TP.mike.hoult24/06/2014

From Seven Sisters to meet Roman Rd, Visited Trig and higher moon scape which is clealy higher. Returned via Roman Rd and St, Illtyd path to ResolvenButeobuteo01/03/2014
Parked in Banwen at end of residential cul-de-sac. Walked SW on forest tracks, mainly Sarn Helen Roman road to summit. Large quarry (or mine) to south, spoil heap close to summit is now higher.jonglew12/10/2013
Cycled across gated level crossing at Nant-y-cafn, legged across cutting the corner of the quarry. Drivers nodded as I stood aside. Made way to trig but higher ground E on bulldozed platform.Eddie09/07/2013
From Banwen to the N. Paths easy to follow until you merge onto the main trucking drag. I just kept heading up but it took me about 30mins to find the trig. I climbed the spoil heap (from the back to save the potential embarrassment of being told to get down!). Loads of trucks passed me on the way down.clivevilla03/04/2013

From the north.Dugswell230/06/2011
Paths from Banwen are officially closed for construction. Nothing happening on a Sunday so I parked in main street and went up regardless. Print of Google Maps sattelite image was very useful.chriswatson07/11/2010
No access from N due to building (mining, wind fm?). Fr car at LC 815075 up track & path to 827077 then steeply up crossing access rds & quarry to Roman rd on ridge & along to trig pt. Construction mounds nearby are higher. Back same route; end 18:05. Drydbb15/03/2010
walked from seven sisters up heol y felin,this provided a forestry commission road up to the sarn helen footpath which has been badly damaged by off road vechicles.Their is extensive landscape work going on this evloving hill.Its a short walk to the trighodder30/07/2009
Drove up track from Seven Sisters to below vast quarry. Steep scramble up scree slopes to top of quarry then thirty metres of trees to track along top and trig. The highest point is now 'work in progress' about 200m further to the E or SE.Aye Jimmy04/05/2009
Trig point, Route: Farmers Arms Resolfen - Sarn Helen - Hirfynydd - Banwen - Coed Y Rhaiadr - Pontneddfechan. Opencast workings are now higher than trig point approx 10m. Very boggy in Coed Y Rhaiadr, paths non existant at Disgwylfa. Not good for dogs.Chris Williams17/01/2009
From NE across rounded off and levelled almost deserted quarry. Different - pleasant enough in its own way.destaylor21/10/2008
Trig revisit. Track from Seven Sisters driveable to quarry gate; simplest ascent probably forks L although I went R up steep zigzags and descended in same direction via wide forest road. I also visited the potential Marilyn twin summit just to SE but it's in process of being quarried.RHW07/06/2008
From Seven Sisters and up through old quarry workings. Returned same way.Dusty03/04/2008
make sure you stick to the roman road and not the quarry.DARRENG25/01/2008
Was told to park inside quarry to ensure vehicle safety. Headed off up left side of cliff face past quite attractive ponds. Arrived at white trig (S2037) at 7.30 am and checked out other possible high point to SEsignyred19/07/2006
We started at Dyffryn Cellwen and headed for the hills to the south. We reached the top after a lovely walk along a woodland. The Main road showed a Restaurant symbol in Dyffryn Cellwen - but turned out to be a microwave in the village shop !!!ChinnockC14/01/2006
