with Alastair and Sarah. Asked permission at Cloesffynnon farm and parked at the end of the tarmac just to the side of the road. Easy ascent of the wind farm access track to trig point for SOTA activation in the fog.M0YDH17/12/2016
6/11 Sixth of eleven on sunny but cold day (Llechwedd Llwyd/Bryn Du/Bryn Mawr/Old Chappel Hill/Pant-Poeth Hill/Peginn Mawr/Graig Iar/Molefre/Pen-y-Ffynnon/Coed y Gaer/Bryn Gwyn)Fergalh05/11/2016
Parked at the windfarm HQ to the NE. Extremely still day, with low cloud. Atmospheric!huwthomas25/08/2016
#593 - 4th of the day. Parked at 00914 80906 and took track up to another windfarm.tim74709/06/2016
With Trefor. 4th Marilyn today. Caught in another heavy snow/hail shower, the story of today. Parked at fork in road above Felin Gythos. Followed wind farm access road to near summit. Great viewpoint and interesting to see the wind farm.mike.hoult29/04/2016
Easy ascent up wind farm track.Lionel Bidwell03/04/2016
Parked on side of road SO0032580387 followed farm tracks on right of ways until near summit which is large cairn with gnarled tree truck sticking out & a nearby trig point. Back at car had a chat with nice farmer who having seen maps was concerned more wind turbines were being planned. Spoils the scenery - he spoke with much wisdom.CodyleCoyote22/03/2016
Parked at 006805 and followed the track to the wind farm and trig point. Continued on and descended the bridleway back to road head, although this hasn't seen any use for a while. A pleasant evening stroll (assuming you don't get worked up about the wind farm) but recommended on a windless day, as the turbines are noisy.mindlessflogger19/06/2015

Final Marilyn of the tour w Jenx. Up the track from farm as described by others to the turbine cluster. Trig has a ghostly feel and is in the process of dis-assembling itself in the grim location, not helped by swirling mist and the turbine din. Bearings sound on the way out. Cairn still has the stump, like the hill in general.nordicstar14/12/2014
A steady climb from the west, making good use of the access track to the wind farm. (PM,CM)gerrybowes27/10/2014
Parked the car and headed east and up the track at dusk. With GB and CM.bolton27/10/2014
With PM & GBCJM27/10/2014
Parked at SO006805 as recommended by others below. Ascended NE by bridleway to ridge, then south over Pegwn Mawr on wind-farm tracks. Visited Crugyn Llwyd before descending.davidpettit8406/09/2014

From forest road near Bwlch-y-Sarnau Hill following track round on ROW (with a short gap) to CROW land for Crugyn Llwyd then over to Pegwn Mawr (gates to wind farm area) before returning on broadly same line. SS26/05/2014

from Bryn Dadlau on gravel tracks all the way - a mountain bike would have made quick work of this visit. lovely day but for the considerable breeze - the whirlygigs turning at quite a lick. the views up here are huge.. yes the turbines do get in the way but also give some grand scale to the place.. Trig has seen better days and the cairn still has the dead pine tree sticking out. A good hill to visit whilst listening to music!!stig_nest13/04/2014
From West.geralddavison22/02/2014
Iain drove all the way up near the top. Hill is covered with windmills.tallblond18/11/2012

4th motorway Marilyn from SW after parking at road junction a little before farm. Warm hazy sunshine with wind turbines turning well in low wind conditions.Dugswell224/04/2010
Left car just below farm at 007805 (10:10) and walked up track to wind farm at summit (anti-clockwise turbines not moving on a still day!). Ancient cairn at summit near trig pt. Back to car 11:30 dbb14/06/2009
From end of road to WSW. Track followed up the hill to forest of turbines. Also a trig in tatty condition, and slightly higher a cairn with dead tree sticking out of it.Aye Jimmy19/03/2009
Parked at 060787 and climbed NW via Banc Du to Hirddywel and then Pegwn Mawr, very hard going and wet in places! Then set off S to Crugwyn-Llwyd avoiding the worst of the bog by going slightly W, keeping to the high ground. Finally we returned to Banc Du,steve hudson18/08/2008
Eerie. Cairn higher than the trig.destaylor15/08/2008
I must have walked close by this summit at least 7 times on the various Across Wales Walks I've completed but never visited it before! This time walked up from farm at SO 008 805 and found what must be the largest windfarm in the UK on the top. I countedsignyred13/11/2007
Up and down from Felin-gytrhos wher dogs alarmed.Eddie02/01/2007
Quick bag after work. Parked on verge at road junction SO006805 and ran up on farm tracks and windfarm roads. Very windy - could hardly hold camera still to take photos. Large windfarm on top.robphys12/11/2004

Parked at SO007805 to the west and again briefly used Glyndŵr?s Way to reach an access track to the wind farm.Then just a matter of using this to walk amongst the turbines and reach the top.garyhoney17/02/2002
8 marilyns solo in mid-Wales, drive and running by 8.20am. Day after Yossi Brain -mountain guide memorial in Walsall & night in bunkhouse at PYB. calm, damp with damp cloud higher up.Chris Pearson14/11/1999
750' climb on access roads from farm to hillside and wind farm. 100 turbines counted from the top - steady whine of blades.arranc19/03/1999

Rhayader Dewey bagging, walk 3/8; Pegwn Mawr and Crugyn Llwyd from road @ 006805, old sign suggesting maybe restricted access, track almost to summit. Smallish tumulus ~1m higher than trig, fine views, big wind farm RHW28/02/1998
